Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum
Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum
Product Description
Product overview
By Erborian — A revolutionary bi-phase night oil-serum powered by 10% PHA and 17 Korean botanical extracts. The aqueous layer delivers active ingredients deep into skin while the oil layer locks them in for overnight transformation — visibly smoother, plumper, and more luminous skin from the very first use.
Innovative Bi-Phase Technology
Two distinct layers — an aqueous serum phase and an oil phase — must be shaken before each use. Once blended, they create a synergistic formula where the water layer delivers active ingredients and the oil layer enhances their absorption and locks them in overnight.

17 Korean Botanical Extracts
Bamboo, Ginseng (white and red), Centella Asiatica, Yuzu, Wild Yam, Kigelia, Giant Horsetail, Licorice, Skullcap, Chamomile, Green Tea, Rosemary, and more — each chosen for targeted skin benefits rooted in Korean herbal tradition.
10% PHA for Gentle Overnight Exfoliation
Gluconolactone (a polyhydroxy acid) gently dissolves dead cell bonds without irritation, stimulates natural hyaluronic acid production, and is gentler than traditional AHAs — making it suitable even for sensitive skin types.
7-in-1 Multi-Perfecting Action
Targets fine lines and wrinkles, skin texture, complexion evenness, luminosity, plumpness, nourishment, and suppleness — all in a single overnight step. Works from the first night with amplified results building over 28 days of consistent use.
Overnight Skin Repair
Designed specifically for nighttime use when the skin's natural regeneration cycle peaks. The formula works in harmony with your skin's repair mechanisms to deliver visible results by morning — waking up to softer, smoother, and more radiant skin.
2024 Beauty Award Winner
Recognized by New Beauty 2024 Beauty Awards as a standout face oil. Praised by editors across skin types — including those who typically avoid face oils — for its lightweight, non-greasy texture and impressive multi-correcting results.
Safety & compatibility
SAFEContains Lactobacillus Ferment and fragrance components (Parfum, Hexyl Cinnamal, Linalool, Citronellol). No retinoids or high-dose salicylic acid, but consult your OB/GYN before use. The PHA (gluconolactone) is generally considered safe, but we recommend checking with your doctor.
Contains Lactobacillus Ferment, Glycine Soja (Soybean) Oil, and Avena Sativa Kernel Oil — all of which may feed Malassezia. If you are actively treating fungal acne, use with caution or choose a formula without fermented ingredients and certain fatty-acid-rich oils.
Rated 1/5 on the comedogenic scale. The primary oils (Squalane, Caprylic/Capric Triglyceride, Sunflower Seed Oil) are lightweight and non-pore-clogging. Clinically confirmed non-comedogenic by Erborian — suitable for combination and oily skin types.
PHA (gluconolactone) is among the gentlest chemical exfoliants available — gentler than AHAs and BHAs. Contains Bisabolol (soothing), Centella Asiatica (calming), and Chamomile Extract. Dermatologically tested and suitable for reactive skin.
Parfum (fragrance), Hexyl Cinnamal, Alpha-Isomethyl Ionone, Linalool, and Citronellol are present in the formula. Those with fragrance sensitivities or allergies should patch test before full-face application.
Erborian advises against combining with retinol or other exfoliants (AHA/BHA) nightly due to overlap in exfoliating function. If you use retinol, alternate nights rather than using both simultaneously. Discontinue if tingling or redness persists.
Free from parabens, sulfates, formaldehyde-releasing agents, phthalates, oxybenzone, and coal tar. Cruelty-free brand — never tested on animals. Products are tested on real volunteers for real results.
The formula is 90% natural origin. No animal-derived ingredients have been identified in the INCI list beyond Lactobacillus Ferment (fermentation-derived). Suitable for vegan skincare routines.
Ingredient breakdown
INGREDIENTSGluconolactone (PHA) ~10%Proven
The star active ingredient — a polyhydroxy acid (PHA) that provides gentle chemical exfoliation by loosening the bonds between dead skin cells. Unlike AHAs, its larger molecular size means slower, more surface-level penetration, making it far less irritating and ideal for sensitive skin. Also acts as a humectant, drawing moisture into the skin, and can stimulate the skin's own hyaluronic acid production over time.
- Function: Exfoliation, anti-aging, humectant, antioxidant protection
- Mechanism: Loosens corneocyte adhesion; promotes cell turnover; stimulates collagen indirectly
- Evidence: Studies show PHA effective in smoothing skin texture after 12 weeks; comparable to AHA with significantly lower irritation potential
- Estimated concentration in this product: ~3.1–3.7% per whatsinmyjar.com analysis (label claims 10% PHA)
Glycerin HighProven
The second ingredient on the INCI list, indicating a significant concentration. Glycerin is one of the most well-researched humectants in skincare — it draws water from the environment and deeper skin layers into the stratum corneum, maintaining plumpness and hydration. It also supports skin barrier function and has demonstrated wound-healing properties.
- Function: Humectant, skin-identical, barrier support
- Evidence: Decades of clinical research confirming efficacy and excellent safety profile across all skin types
- Comedogenic Rating: 0/5 — non-pore-clogging
Squalane MidProven
A stable, plant-derived emollient that mimics the skin's own sebum. Squalane is lightweight, non-greasy, and rapidly absorbed, providing softness and suppleness without clogging pores. It also has antioxidant properties and helps form a protective barrier to reduce transepidermal water loss (TEWL).
- Function: Emollient, barrier protection, antioxidant
- Source: Sugarcane or olive-derived in modern formulations (not shark-derived)
- Comedogenic Rating: 0/5 — excellent for oily and acne-prone skin
Phyllostachys Bambusoides Extract + Juice MidProven
Bamboo appears twice in this formula — as an extract and as bamboo water/juice — underlining its importance. Rich in silica, antioxidants, and natural moisturizing factors, bamboo extract supports skin hydration, barrier function, and skin firmness. Bamboo juice delivers a high concentration of trace minerals and is a hallmark K-beauty ingredient known for its skin-soothing and plumping properties.
- Function: Antioxidant, hydration, skin barrier support, anti-inflammatory
- Key nutrients: Silica (firms), chlorophyll (antioxidant), amino acids
- K-beauty hallmark: Traditional Korean botanical used for skin vitality and regeneration
Panax Ginseng Root Extract ActiveProven
One of the most studied anti-aging botanical ingredients in K-beauty. Panax Ginseng (red and white varieties) contains ginsenosides — bioactive saponins that stimulate collagen synthesis, inhibit matrix metalloproteinases (enzymes that degrade collagen), and protect against UV-induced skin damage. Erborian cites a 2% ginseng complex as comparable in efficacy to 1% retinol in ex vivo skin testing.
- Function: Anti-aging, collagen stimulation, antioxidant, brightening
- Active compounds: Ginsenosides Rg1, Rb1, Rc — proven collagen-stimulating activity
- Clinical claim: Erborian: "2% Ginseng complex as effective as 1% Retinol" (ex vivo test on skin explants, 72 hours)
Citrus Junos Fruit Extract (Yuzu) ActiveProven
Korean Yuzu is a citrus fruit rich in Vitamin C, flavonoids, and hesperidin. It brightens skin tone, inhibits melanin formation, and helps even out post-inflammatory hyperpigmentation. Yuzu extract is specifically highlighted by Erborian as the key ingredient targeting complexion evenness in this formula.
- Function: Brightening, antioxidant, complexion evening, Vitamin C-like activity
- Key compounds: Hesperidin, narirutin, limonene, Vitamin C precursors
- K-beauty significance: Traditional citrus used in Korean skincare for generations; featured K-beauty staple
Sodium Hyaluronate ActiveProven
The sodium salt form of hyaluronic acid — more stable and better able to penetrate into the upper skin layers than high molecular weight HA. Sodium hyaluronate can hold up to 1,000 times its weight in water, plumping skin cells, reducing the appearance of fine lines, and improving overall skin suppleness. It also reinforces the skin's moisture barrier over time.
- Function: Humectant, plumping, anti-wrinkle, barrier support
- Evidence: Extensive clinical evidence for hydration, wrinkle reduction, and skin elasticity improvement
- Comedogenic Rating: 0/5
Zinc PCA ActiveProven
A highly bioavailable form of zinc combined with pyrrolidone carboxylic acid (PCA) — a natural moisturizing factor. Zinc PCA regulates sebum production, has antibacterial properties, and helps improve overall skin quality and texture. It's particularly beneficial for oily, combination, and acne-prone skin types, helping to minimize pore appearance and control shine.
- Function: Sebum regulation, antibacterial, texture improvement, skin quality
- Evidence: Clinically shown to reduce sebum secretion; anti-inflammatory properties confirmed in vitro
- Double benefit: PCA component also acts as a humectant, hydrating while zinc controls oil
Centella Asiatica Extract ~0.3–0.55%Proven
A K-beauty superstar ingredient with centuries of use in traditional medicine. Centella Asiatica (CICA) contains triterpenoids (asiatic acid, madecassic acid, asiaticoside) that promote collagen synthesis, strengthen the skin barrier, reduce inflammation, and accelerate wound healing. It's the soothing backbone of the formula, counterbalancing the mild exfoliating action of PHA.
- Function: Barrier repair, soothing, collagen stimulation, wound healing, anti-inflammatory
- Key compounds: Asiaticoside, asiatic acid, madecassic acid
- Evidence: Multiple peer-reviewed studies confirming wound healing, anti-inflammatory, and collagen-stimulating effects
Bisabolol Low-MidProven
A natural compound derived from chamomile (or synthesized) with powerful soothing and anti-inflammatory properties. Bisabolol calms redness, reduces irritation, and enhances the penetration of other active ingredients. It also has mild skin-brightening effects and has been shown to accelerate skin recovery after exfoliation — an ideal companion to the PHA in this formula.
- Function: Anti-inflammatory, soothing, penetration enhancer, brightening
- Synergy: Works with PHA to soothe any potential irritation from exfoliation; enhances active ingredient absorption
Capsicum Annuum Fruit Extract (Red Pepper) ActivePromising
Red Pepper extract is specifically highlighted by Erborian as the luminosity-boosting ingredient in this formula. Rich in capsaicin, carotenoids, and Vitamin C, it stimulates micro-circulation, promotes a warm glow from within, and helps combat dullness. The mild warming sensation some users report after application is attributed to this ingredient activating skin circulation.
- Function: Luminosity, micro-circulation, antioxidant (Vitamin C, carotenoids)
- Active compounds: Capsaicin (circulation), carotenoids (antioxidant/glow), Vitamin C
- Note: May cause mild tingling upon application — this is normal and not a sign of irritation for most users
Glycyrrhiza Glabra Root Extract (Licorice) ActiveProven
Licorice root is one of the most evidence-backed botanical brightening agents in skincare. Glabridin, its primary active compound, inhibits tyrosinase (the enzyme responsible for melanin production) and reduces UV-induced skin darkening. It also has strong anti-inflammatory properties, helping to calm post-acne marks and redness over time.
- Function: Brightening, tyrosinase inhibition, anti-inflammatory, antioxidant
- Key compound: Glabridin — proven tyrosinase inhibitor; 16x more potent than hydroquinone in some studies (without the risks)
Polygonum Cuspidatum Root Extract (Japanese Knotweed) ActivePromising
A potent source of resveratrol — one of the most studied polyphenol antioxidants in skincare. Resveratrol from Japanese Knotweed neutralizes free radicals, inhibits inflammation, and supports skin barrier integrity. It has also shown preliminary evidence for inhibiting melanin synthesis, contributing to the formula's complexion-evening action.
- Function: Antioxidant (resveratrol), anti-inflammatory, potential brightening
- Key compound: Trans-resveratrol — neutralizes oxidative stress; reduces TEWL in compromised skin

Where it fits in your routine
ROUTINEApply to clean, dry skin each evening. Shake bottle well before use. Warm 3–4 drops in your palms, then press gently onto face and neck. Can be used alone or before your night cream. Do not follow with another exfoliant on the same night.
How to use
HOW TO USEDouble Cleanse
Begin with an oil-based cleanser to remove makeup and SPF, followed by a gentle water-based cleanser to remove any remaining impurities. Start with clean, completely dry skin for maximum product absorption.
Shake the Bottle
This is essential — the bi-phase formula separates into two layers between uses. Shake vigorously for 5–10 seconds to fully blend the aqueous and oil phases before each application. You'll see the layers merge into a unified milky-oil texture.
Dispense 3–4 Drops
Empty the dropper pipette first, then refill to draw up a measured amount. Use 3–4 drops per application — a little goes a long way. This product is concentrated; using more will not amplify results and may increase the risk of sensitivity.
Warm Between Palms
Press a few drops between both palms and gently rub together to warm the product. This step activates the formula, helps the two phases fully emulsify, and ensures more even and efficient application across the skin.
Press and Pat Onto Skin
Using your fingertips, press and pat the warmed product across the entire face and neck using upward motions. Avoid rubbing, which can cause pilling. Pay extra attention to fine lines around the eyes, mouth, and forehead.
Optional: Follow with Night Cream
Skin Therapy can be used alone as your complete night step or layered under a richer night cream for extra nourishment. Wait 30–60 seconds for the oil-serum to absorb before applying any additional layers to avoid pilling.
Who is it for?
WHOPerfect for you if:
- You want an all-in-one overnight treatment for multiple concerns
- Your skin looks dull, tired, or uneven in tone
- You're addressing early-to-moderate fine lines and loss of radiance
- You prefer a minimalist nighttime routine (one product after cleansing)
- You have combination, oily, or normal skin looking for lightweight nourishment
- You love K-beauty and botanical-forward formulations
- You want visible overnight results plus long-term anti-aging benefits
- You're new to face oils and want a non-greasy introduction
Consider alternatives if:
- You are pregnant or breastfeeding (consult your doctor first)
- You have active fungal acne (Malassezia folliculitis)
- You are highly fragrance-sensitive or allergic to citrus compounds
- You want a very rich, deeply occlusive overnight mask-style treatment for very dry skin
- You are already using a potent retinol every night and want to avoid over-exfoliation
- You have active rosacea with extreme vasoreactivity (Red Pepper Extract may trigger flushing)
Skin type compatibility
SKIN TYPESExceptionally well-suited. The bi-phase formula absorbs quickly without adding greasiness. Zinc PCA regulates sebum, PHA refines pores and texture, and squalane provides non-comedogenic hydration. Leaves a dewy (not oily) finish.
Good for dry skin seeking radiance and anti-aging benefits. Glycerin, hyaluronic acid, squalane, and betaine provide meaningful hydration. However, very dry skin may want to layer a richer night cream on top for added occlusion and barrier repair.
Ideal. The lightweight oil-serum texture balances across the T-zone and drier cheek areas simultaneously. Zinc PCA controls oil where needed while the hydrating actives nourish drier zones — no need to zone-apply.
The PHA is among the gentlest exfoliants available, and soothing ingredients like Bisabolol, Centella Asiatica, and Chamomile are included. However, fragrance components and Red Pepper Extract may cause reactions in the most reactive users. Patch test recommended.
Non-comedogenic formula with Zinc PCA (antibacterial, sebum-regulating) and PHA (anti-comedogenic, pore-clearing). Centella Asiatica helps calm post-acne inflammation. However, if fungal acne is a concern, the Lactobacillus Ferment and certain oils may be problematic.
The primary demographic this formula targets. Ginseng (retinol-comparable anti-aging activity), PHA (cell renewal), Hyaluronic Acid (plumping), and Licorice (brightening age spots) work in concert to address the full spectrum of skin aging concerns overnight.
Results timeline
6+ WEEKSInstant Softness, Smoother Texture & Glow
The PHA immediately begins its gentle exfoliation, loosening dead cell bonds on the skin surface. Combined with the hydrating action of glycerin, hyaluronic acid, and squalane, the skin wakes up noticeably softer, more supple, and with a healthy radiance. Signs of skin fatigue appear reduced.
95% noticed softer, smoother skin from night 1*Visible Fine Line Smoothing & Even Tone
With consistent nightly use, the compounding effect of PHA exfoliation, Yuzu brightening, and Ginseng anti-aging activity begins to show. Fine lines and dehydration lines appear reduced, skin tone looks more even, and the complexion develops a more uniform clarity.
90% saw fine lines visibly smoothed or reduced after 14 days*Plumper, Firmer, More Confident Skin
By this stage, Ginseng extract (with its collagen-stimulating ginsenosides), combined with sustained hydration from hyaluronic acid and Polygonatum (Solomon's Seal), produces a measurable improvement in skin firmness and elasticity. Pores appear minimized, texture is refined, and skin looks healthier at baseline.
95% felt happier looking at their bare skin after 28 days*Long-Term Anti-Aging & Skin Transformation
Extended use allows the deeper-acting botanical anti-aging ingredients (Wild Yam, Kigelia, Giant Horsetail, Licorice) to accumulate visible results. Skin appears more resilient, wrinkles less pronounced, complexion more luminous, and overall skin quality meaningfully improved compared to baseline.
93% felt more confident in their bare skin after 28 days**Consumer test results provided by Erborian on 41 volunteers (Night 1, 14 days). Individual results may vary.

Budget-friendly alternatives (dupes)
DUPES
Fermentation-forward K-beauty serum with antioxidant-rich plant ferments, similar brightening and anti-aging positioning. Lacks the bi-phase innovation and PHA exfoliation of Skin Therapy but delivers comparable glow and ferment-derived skin renewal. Fragrance-free version available.
Delivers the same core PHA (gluconolactone) exfoliation mechanism at a much higher 12% concentration, plus mandelic acid for brightening. Significantly cheaper but lacks the botanical complexity, ginseng anti-aging actives, and nourishing oil phase. Not a true oil-serum hybrid.
Premium K-beauty overnight treatment also centered on Korean botanicals including ginseng, and similarly targets multiple aging concerns. Richer, more occlusive texture — better for dry skin seeking deep overnight nourishment. Does not contain PHA exfoliation. Premium brand with a similarly luxurious finish.

Storage & shelf life
12 MONTHS12 months after opening. Look for the open jar symbol on packaging indicating "12M." The bi-phase formula's natural ingredients are best used within this period to ensure maximum potency of the PHA, botanical extracts, and antioxidants.
Store in a cool, dry place away from direct sunlight and heat. Avoid leaving near a bathroom window where steam and humidity can degrade the formula. Refrigeration is optional but can enhance the soothing sensation on application.
Glass dropper bottle with pipette applicator. The dropper design minimizes product waste and contamination compared to a pump or open cap. The glass construction preserves ingredient integrity and prevents the oils from degrading plastic containers.
Yes — the 30ml bottle is within the 100ml TSA carry-on liquid limit. A 10ml travel-size version is also available separately. Ensure the dropper cap is tightly secured before travel to prevent leakage.
Frequently asked questions
FAQThe formula does not contain retinoids, high-dose salicylic acid, or hydroquinone — the primary ingredients that are clearly contraindicated in pregnancy. The PHA (gluconolactone) is generally considered safe. However, the product does contain Parfum (fragrance), Lactobacillus Ferment, and botanical extracts including Capsicum (Red Pepper) — all of which are typically avoided during pregnancy out of an abundance of caution. We always recommend consulting your OB/GYN or midwife before starting any new skincare product during pregnancy or breastfeeding. Do not self-assess based on online information alone.
This product is NOT considered fungal acne safe. It contains Lactobacillus Ferment (a fermented ingredient that can feed Malassezia), Glycine Soja (Soybean) Oil, and Avena Sativa (Oat) Kernel Oil — both of which are fatty acid-rich oils that may trigger Malassezia folliculitis in susceptible individuals. If you have confirmed fungal acne (Malassezia folliculitis), we recommend looking for products specifically formulated without these ingredients. If you're unsure whether your breakouts are fungal or bacterial, a dermatologist consultation is the best course of action.
Erborian specifically advises against combining this product nightly with retinol or other exfoliants (AHA/BHA) due to overlap in exfoliating function and the risk of over-exfoliation and irritation. If you use retinol, alternate nights: use Skin Therapy on some evenings and retinol on others — 2–3 times per week each is a commonly recommended approach. Vitamin C (used in a morning routine) is compatible, as this is a nighttime product. If you experience any tingling, redness, or discomfort from layering, discontinue the combination and consult a dermatologist.
This product is formulated for all skin types and is specifically highlighted by Erborian as suitable for combination and oily skin — an uncommon claim for an oil-based product. Its lightweight bi-phase texture absorbs without greasiness, and Zinc PCA helps regulate sebum. It is excellent for combination, oily, normal, and mature skin types. Dry skin can benefit but may need an additional night cream. Sensitive skin can use it with caution — patch test recommended due to fragrance and Red Pepper Extract. It is not recommended for fungal acne-prone skin.
According to Erborian's consumer testing (41 volunteers): 95% noticed softer, smoother, and more radiant skin from the very first night. After 14 days, 90% reported fine lines and wrinkles were visibly smoothed or reduced. After 28 days, 95% felt happier looking at their bare skin. For deeper anti-aging benefits (wrinkle depth reduction, elasticity improvement, collagen-level changes from Ginseng), allow at least 6–8 weeks of consistent nightly use. As with all active skincare, consistency is the key — missing nights will slow progress.
Apply as the last step of your evening skincare routine — after cleansing, toning, and any lighter water-based serums. Because it contains an oil phase, it should go on after water-based products to seal in moisture and active ingredients. Skin Therapy can be used before or instead of your night cream — it is concentrated enough to serve as a complete last step on its own. In the Erborian system, they recommend pairing with the Skin Therapy Eye Cream (applied first) and the Skin Therapy Milky Serum (applied before the oil). Do not apply sunscreen on top — this is a PM-only product.
No — the formula is non-comedogenic, with a comedogenic rating of 1/5. The primary emollient oils used (Squalane rated 0/5, Caprylic/Capric Triglyceride rated 0–1/5, Sunflower Seed Oil rated 0–2/5) are all low on the comedogenic scale. Zinc PCA actively helps regulate sebum production, and the PHA gently keeps pores clear of dead cell buildup. Erborian confirms this formula is suitable for combination and oily skin without clogging pores. However, as with any product, individual reactions can vary — if you have very congestion-prone skin, patch test on your cheek or jawline for 1–2 weeks before applying all over.
The Period After Opening (PAO) is 12 months, indicated by the "12M" open jar symbol on the packaging. At the recommended usage of 3–4 drops per night, a 30ml bottle typically provides approximately 2–3 months of nightly use, well within the PAO window. Store in a cool, dry location away from sunlight and heat to maintain ingredient stability. The glass dropper bottle helps protect the formula from degradation. Do not use if the product has changed color, consistency, or smell significantly from when first opened.
Verdict: The Erborian Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum is a genuinely innovative K-beauty night treatment that delivers on its ambitious multi-targeting claims. Its unique bi-phase technology — combining a PHA-powered aqueous serum with a nourishing botanical oil phase — produces a texture that feels unlike any conventional face oil: lightweight, fast-absorbing, and non-greasy, yet intensely nourishing. The 17-botanical Korean herbal complex, anchored by Ginseng (with retinol-comparable anti-aging evidence), Centella Asiatica, Yuzu, and Bamboo, delivers genuine overnight radiance and measurable long-term anti-aging benefits. The 10% PHA provides gentle but effective exfoliation even sensitive skin can tolerate. Deductions for the presence of fragrance (limiting fragrance-sensitive users), Lactobacillus Ferment (not fungal acne safe), and a price point that feels high for 30ml. That said, this is a New Beauty 2024 Award winner that impressed self-described face-oil skeptics — rare praise that speaks to its broad appeal and efficacy. If you're looking for one powerful, multi-correcting overnight oil-serum rooted in Korean skincare science, this is among the best in its category.

Understanding Simple Alcohols
Alcohol ingredients are widely used in cosmetics and come in different types. For the most part alcohols are not problematic at all. However one type of alcohols, simple alcohols can be quite drying to the skin because it evaporates very quickly. This can cause irritation which can also lead to other skin complications. These alcohols should never be used alone on your skin, but combined with other cosmetic ingredients, they are normally without issue. However, for some people with sensitive and easily irritable skin, avoiding products with these simple alcohols may be beneficial. If you find your skin doesn't like these simple alcohols, then free feel to avoid them by looking out for the Alcohol-Free icon.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.

Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.

Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
What are Notable Effects & Ingredients?
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

What are Ingredients Related to Skin Type?
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
Pro Tip Alert!
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

What is the Ingredient Safety Breakdown?
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
Pro Tip Alert!
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
