Ingredient breakdown
INGREDIENTSAscorbic Acid (Vitamin C) 15%Proven
Pure L-Ascorbic Acid is the gold standard form of Vitamin C in skincare. At 15%, it sits in the clinically effective range (10–20%) for stimulating collagen, brightening hyperpigmentation, and providing potent antioxidant protection against UV and pollution damage.
- Clinical data: Concentrations of 10–20% are proven to stimulate collagen synthesis and reduce melanin production.
- Photoprotection: L-Ascorbic Acid enhances UV protection when used under sunscreen, reducing erythema and photodamage.
- Stability note: Requires low pH (~2.5–3.5) for optimal skin penetration. This formula is pH-adjusted with Sodium Hydroxide.
Alcohol Denat. ~10–15%Functional
Denatured alcohol acts as a solvent and penetration enhancer, helping Vitamin C absorb into the skin quickly. It also contributes to the lightweight, non-sticky texture of the serum.
- Function: Improves absorption of active ingredients and creates a fast-drying, non-greasy finish.
- Trade-off: May be drying for sensitive or compromised skin barriers with prolonged use.
Glycerin ~2–3%Proven
A classic humectant and skin-identical ingredient that attracts water to the upper skin layers, providing hydration and helping to maintain a healthy skin barrier. Comedogenic rating of 0.
- Efficacy: Effective at concentrations as low as 3%, with greater benefits for dry skin at higher concentrations.
- Barrier support: Keeps skin lipids in a healthy liquid crystal state, protecting against irritation and restoring barrier function.
Hydrolyzed Hyaluronic Acid ~0.1–0.35%Proven
A low-molecular-weight form of hyaluronic acid that penetrates deeper into the skin compared to standard HA. Attracts and holds up to 1,000 times its weight in water, plumping and hydrating from within.
- Penetration: Hydrolyzed (smaller) molecules can reach deeper skin layers for more effective hydration.
- Synergy: Counteracts any potential drying effects from the Vitamin C and alcohol in the formula.
Tocopherol (Vitamin E) TraceProven
Pure Vitamin E is a powerful lipid-soluble antioxidant that works synergistically with Vitamin C to enhance its photoprotective effects and extend its stability in the formula.
- Synergy: The combination of Vitamins C and E provides significantly greater antioxidant protection than either ingredient alone.
- Stabilizer: Helps prevent oxidation of Ascorbic Acid, extending the shelf life and efficacy of the serum.
Neohesperidin Dihydrochalcone TracePromising
A flavonoid derived from citrus with potent anti-glycation properties. Glycation occurs when sugar molecules damage skin proteins like collagen and elastin, accelerating visible aging.
- Anti-glycation: In vitro studies show it helps protect skin proteins from sugar-induced damage, preserving firmness and elasticity.
- Antioxidant: Provides additional free radical scavenging alongside Vitamins C and E.
Pinus Pinaster Bark/Bud Extract (Pycnogenol) TracePromising
A botanical extract from French maritime pine bark, rich in proanthocyanidins. Known for its strong antioxidant capacity and ability to support collagen and elastin synthesis.
- Antioxidant power: Proanthocyanidins are among the most potent natural antioxidants, complementing the Vitamin C and E in this formula.
- Collagen support: Research suggests it may help bind to collagen and elastin, supporting skin structure and firmness.
Dipropylene Glycol SolventFunctional
A lightweight solvent and humectant that helps dissolve ingredients and improve the texture of the formula while providing mild moisturizing benefits.
- Function: Enhances the solubility of active ingredients and contributes to the serum's lightweight, watery consistency.

Where it fits in your routine
ROUTINEUse every morning as the first serum step after cleansing. Always follow with SPF 30+ during the day. Can be layered under other serums and moisturizer.
How to use
HOW TO USECleanse & Dry
Start with freshly cleansed, completely dry skin. Vitamin C absorbs best on dry skin at low pH, so avoid applying to damp skin.
Dispense 4–5 Drops
Turn the precision dose applicator upside down and gently squeeze at the base to release the formula. Place 4–5 drops onto your fingertips.
Apply to Face & Neck
Gently press and pat the serum across your entire face and neck, avoiding the eyelid area. Do not rub vigorously.
Follow with Moisturizer & SPF
Allow 30–60 seconds for the serum to absorb, then layer your moisturizer and a broad-spectrum SPF 30+ sunscreen. Sunscreen is essential when using Vitamin C.

Storage & shelf life
6 MONTHS6 months after opening. However, for best potency, use within 2–3 months. Discard immediately if the serum turns dark orange or brown — this indicates the Vitamin C has oxidized.
Store in a cool, dark place away from direct sunlight and heat. Refrigeration is recommended to extend potency and slow oxidation. Keep the cap tightly closed after each use.
UV-tinted glass bottle with precision dose squeeze applicator. The tinted glass helps protect the Vitamin C from light degradation, and the squeeze applicator minimizes air exposure.
Yes — 20ml is well under the 100ml TSA/airport liquid limit. Compact glass bottle fits easily in any travel bag or carry-on toiletry pouch.
Frequently asked questions
FAQYes. This serum contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens — all of which are commonly flagged during pregnancy. The active ingredients (Vitamin C, Vitamin E, Hyaluronic Acid, Glycerin) are considered safe for use during pregnancy and breastfeeding. However, always consult your healthcare provider before introducing new skincare products during pregnancy.
Yes. This serum is free from fermented ingredients, fatty acids, esters, polysorbates, and oils that are known to feed malassezia yeast. SkinCarisma confirms the formula contains no flagged fungal acne triggers. The minimalist 11-ingredient formula makes it one of the safest Vitamin C serums for fungal acne sufferers.
It is best to use Vitamin C and retinol at different times of day — Vitamin C in the morning for antioxidant protection and retinol at night for cell turnover. Using them together can cause irritation, especially at this concentration (15%). For AHA/BHA, alternate days or apply them at least 30 minutes apart to avoid lowering pH too aggressively. Always introduce one active at a time to assess tolerance.
This serum works best for oily, combination, normal, and acne-prone skin types thanks to its oil-free, lightweight, fast-absorbing formula. It is also suitable for sensitive skin (fragrance-free, allergy tested) though a patch test is recommended. Those with very dry skin may find it insufficiently hydrating on its own and should pair it with a rich moisturizer.
Most users notice an immediate glow and improved hydration within 72 hours. Visible brightening and smoother skin texture typically appear within 10–14 days of consistent daily use. Significant improvement in dark spots, fine lines, and overall radiance is usually seen at 4–8 weeks. In clinical consumer tests, 100% of participants reported brighter skin and reduced wrinkles after 3 months.
Apply as the very first treatment step in your morning routine, directly after cleansing and toning on dry skin. Vitamin C is most effective when applied before other serums because it works best at low pH on bare skin. Follow with your moisturizer and always finish with a broad-spectrum SPF 30+ sunscreen during the day.
No. This serum has a very low comedogenic rating of 1/5. It is oil-free, non-comedogenic, and contains no heavy occlusives or pore-clogging ingredients. Glycerin (comedogenic rating 0) and Hydrolyzed Hyaluronic Acid are both lightweight humectants that hydrate without blocking pores. It is also fungal acne safe.
The official PAO (Period After Opening) is 6 months. However, because pure L-Ascorbic Acid is highly unstable and degrades quickly when exposed to air and light, it is strongly recommended to use the product within 2–3 months of opening for maximum potency. Store in a cool, dark place (or refrigerator) and discard if the color changes to dark orange or brown.
Verdict: Vichy LiftActiv Vitamin C Serum is a solid mid-range brightening serum backed by L'Oréal's clinical research and over 80 years of French pharmacy expertise. Its minimalist 11-ingredient formula with 15% pure Ascorbic Acid delivers clinically proven brightening results within 10 days, while being safe for pregnancy, fungal acne, and acne-prone skin. The main trade-offs are its small 20ml bottle size, the presence of drying alcohol, and the lack of ferulic acid for enhanced stability. For those who prioritize a clean, potent, and no-fuss Vitamin C serum at an accessible price, this is an excellent choice — especially for oily and combination skin types looking to tackle dullness, uneven tone, and early signs of aging.

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.

EU Allergen-Free
EU Allergen-Free
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.
Also note, the EU Allergen Free label is not personalized for your own allergies you may have and it does not constitute as medical advice.

Fungal Acne (Molassezia) Safe
Fungal Acne (Molassezia) Safe
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.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
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
Notable Effects & Ingredients
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.
