COSRX
The Alpha-Arbutin Discoloration Care Hydrogel Mask
€5.06
The rare pigmentation mask whose list actually backs the claim: niacinamide fourth, alpha-arbutin twelfth and acetyl glucosamine nineteenth - three actives that work on different steps of the same pathway - with ferulic acid and glutathione behind them. Five ceramides, cholesterol and phytosphingosine close it out, and there is no fragrance.
What stands out in the list
Worked out from the ingredients, not the packaging claims.
1 concentration-capped ingredient
EU law sets a maximum for Alpha-Arbutin. Products on sale in the EU must comply.
2 ingredients flagged for pregnancy
Alpha-Arbutin, Glutathione are usually avoided or used with caution during pregnancy. This is what the ingredient entries say, not medical advice, so ask your midwife or doctor.
No fragrance or declared allergens
Nothing in the list is Parfum/Fragrance or an EU-declared fragrance allergen.
No drying alcohol
No ethanol, alcohol denat. or isopropyl alcohol in the list. Fatty alcohols such as cetearyl alcohol are not drying and do not count.
Barrier-supporting actives
Contains Niacinamide, Panthenol, Allantoin, ingredients with reasonable evidence for calming and supporting the skin barrier.
