Texture & feel
SENSORYTargeted Spot Treatment
Thick, velvety texture adheres to specific areas for maximum effectiveness on dark spots and post-acne marks.
Dual-Action Formula
Mandelic Acid inhibits melanin production while Retinol accelerates cell turnover for comprehensive brightening.
Hydrating Exfoliation
Glycerin draws moisture in while you exfoliate, preventing the dryness commonly associated with acid treatments.
Gentle AHA
Mandelic acid has a larger molecular size than glycolic, penetrating slowly for reduced irritation — ideal for sensitive skin.
Safety & compatibility
SAFENot recommended. Contains 0.1% Retinol which should be avoided during pregnancy and breastfeeding. Consult your doctor.
Not safe. Contains Polysorbate 20, Coco-Caprylate/Caprate, and Sunflower Seed Oil which can feed malassezia yeast.
AHAs increase photosensitivity. Always use SPF 30+ the morning after application and limit sun exposure.
Mandelic acid's larger molecular weight allows slower, more even penetration — gentler than glycolic or lactic acid.
Already contains 0.1% retinol. If using additional retinol products, alternate days or reduce frequency to avoid irritation.
Can be used with other AHAs like Glycolic or Lactic Acid, but start slowly and monitor for irritation.
Ingredient breakdown
INGREDIENTSMandelic Acid 10%Proven
An alpha-hydroxy acid (AHA) derived from bitter almonds with a larger molecular weight (152.1 daltons) than glycolic acid (76.0 daltons). This allows for slower, more even skin penetration with less irritation.
- Mechanism: Dissolves the bonds between dead skin cells, promoting exfoliation and cell turnover
- Melanin Inhibition: Helps reduce melanin production to fade hyperpigmentation and dark spots
- Antibacterial: Has natural antibacterial properties that help with acne-prone skin
- Clinical Evidence: Studies show mandelic acid effectively treats hyperpigmentation with fewer side effects than stronger AHAs
Encapsulated Retinol 0.1%Proven
A vitamin A derivative that accelerates cell turnover and promotes collagen production. The encapsulated form provides time-released delivery for reduced irritation.
- Cell Turnover: Speeds up the natural skin renewal process to fade dark spots faster
- Anti-Aging: Proven to reduce fine lines and improve overall skin texture over time
- Synergy: Works synergistically with mandelic acid to enhance brightening effects
Glycerin 2%Proven
A powerful humectant that draws moisture into the skin and helps maintain the skin barrier during exfoliation.
- Hydration: Attracts water molecules to the skin surface for lasting moisture
- Barrier Support: Helps prevent the dryness and irritation that can accompany acid treatments
- Compatibility: Works well at concentrations up to 20-40% for enhanced benefits
Ethyl Ferulate TracePromising
A potent antioxidant derived from ferulic acid that helps protect skin from environmental stressors and enhances the stability of other active ingredients.
- Antioxidant: Neutralizes free radicals that contribute to premature aging and hyperpigmentation
- UV Protection: Provides additional defense against UV-induced skin damage
Humulus Lupulus (Hops) Extract TracePromising
A botanical extract with soothing and antioxidant properties that helps calm the skin during the exfoliation process.
- Soothing: Helps reduce potential irritation from active ingredients
- Antioxidant: Provides additional protection against oxidative stress

Follow with Moisturizer
Seal in the treatment with your preferred moisturizer. In the morning, always finish with SPF 30+.
Who is it for?
WHOPerfect for you if:
- You have post-acne dark spots or hyperpigmentation
- You want a gentle introduction to chemical exfoliation
- You have sensitive skin that can't tolerate glycolic acid
- You're dealing with uneven skin tone and texture
- You want both exfoliation and retinol benefits in one product
- You prefer targeted spot treatments over all-over applications
- You have hormonal breakouts that leave marks
Consider alternatives if:
- You are pregnant or breastfeeding (contains retinol)
- You have fungal acne/malassezia folliculitis
- You need to treat large areas (small tube may not last)
- You have very stubborn, old hyperpigmentation (may need stronger treatment)
- You're already using strong retinoids or multiple acids
- You cannot commit to daily SPF use
Skin type compatibility
SKIN TYPESEffective for oily skin, though the gel-cream texture may feel slightly rich. Best used as a targeted spot treatment rather than all-over application.
Excellent choice for dry skin. The creamy texture and 2% glycerin provide hydration while you exfoliate, preventing the dryness common with acid treatments.
Works beautifully on combination skin. Use on targeted areas without disrupting the balance of different facial zones.
One of the best choices for sensitive skin. Mandelic acid's large molecular size penetrates slowly, causing less irritation than glycolic or lactic acid.
Good for acne-prone skin due to mandelic acid's antibacterial properties. However, not suitable for fungal acne. Comedogenic rating 2/5.
Excellent for darker skin tones. Mandelic acid is not melanotoxic and is less likely to cause post-inflammatory hyperpigmentation than stronger acids.

Frequently asked questions
FAQNo, this product is not safe during pregnancy or breastfeeding. It contains 0.1% Retinol, a vitamin A derivative that should be avoided during pregnancy as it may cause fetal harm. The brand explicitly recommends avoiding use during pregnancy and breastfeeding. Consult your doctor before use, and consider retinol-free alternatives like The Ordinary Mandelic Acid 10% + HA or Good Molecules Mandelic Acid Serum.
No, this product is not fungal acne safe. It contains several ingredients that can feed malassezia yeast, including: Polysorbate 20, Coco-Caprylate/Caprate, Candelilla/Jojoba/Rice Bran Polyglyceryl-3 Esters, Copernicia Cerifera Cera (Carnauba Wax), and Helianthus Annuus Seed Oil (Sunflower Oil). If you have fungal acne, consider Good Molecules Mandelic Acid Serum or Almond Clear serums which are formulated to be malassezia-safe.
This product already contains 0.1% retinol, so be cautious when combining with additional retinoids to avoid over-exfoliation. It can be used with other AHAs (glycolic, lactic acid), but introduce slowly and monitor for irritation. For vitamin C, use in the morning and mandelic acid at night to avoid potential instability. For BHA (salicylic acid), you can use them on alternating days or layer BHA first, then mandelic. Always listen to your skin and reduce frequency if you experience redness, peeling, or sensitivity.
This treatment works for all skin types but is particularly excellent for: Sensitive skin (mandelic acid is the gentlest AHA), dry skin (contains hydrating glycerin), melanin-rich skin (non-melanotoxic, less likely to cause PIH), and combination skin (works well as targeted spot treatment). It's also good for those new to chemical exfoliants. Less ideal for very oily skin seeking a lightweight texture, or those with fungal acne.
According to clinical studies and user reviews: Week 1-2: Skin feels softer and smoother. Week 2-4: Visible brightening and fresh marks begin fading. Week 4-6: Significant reduction in dark spots (94% of clinical trial participants agreed). Week 8+: Maximum results for stubborn hyperpigmentation. Patience and consistency are key — using more product won't speed up results and may cause irritation.
Use in your PM routine only: 1) Cleanser, 2) Hydrating serum (optional), 3) Mandelic Acid Treatment (this product), 4) Eye cream, 5) Moisturizer. In the morning, always apply SPF 30+ as this product increases sun sensitivity. The brand recommends applying after cleansing and hydrating, patting a thin layer onto affected areas, then following with moisturizer.
This product has a comedogenic rating of 2/5, meaning it has a low-to-moderate chance of clogging pores. The main ingredient of concern is Cetearyl Alcohol (rating 2). For most people, this won't cause breakouts, but those with highly acne-prone skin should patch test first. The mandelic acid itself actually helps unclog pores through exfoliation. Note that this is NOT fungal acne safe due to the esters and oils in the formula.
The product has a 12-month Period After Opening (PAO). Store in a cool, dry place away from direct sunlight, as both mandelic acid and retinol can degrade with light exposure. The tube is made from 65% post-consumer recycled plastic and is fully recyclable. The 15ml tube typically lasts 2-3 months with regular targeted use; the 30ml version is better value for frequent users.
Verdict: The Inkey List Mandelic Acid Treatment is an excellent choice for those seeking a gentle yet effective solution for post-acne marks and hyperpigmentation. The unique combination of 10% mandelic acid and 0.1% retinol delivers clinically-proven results, with 94% of users seeing reduced dark spots. Its larger molecular size makes it ideal for sensitive and melanin-rich skin. The main limitations are its unsuitability for pregnancy/breastfeeding and fungal acne-prone skin, plus the small tube size. For the price point, it offers impressive results — just be patient and consistent, and always wear SPF.

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.

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.

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

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.
