How to read a skincare ingredient list
What INCI means
INCI (International Nomenclature of Cosmetic Ingredients) gives every ingredient one international name. The same humectant on a Korean, French or American label is always called Glycerin. That is why the most reliable way to check skincare ingredients is the INCI list that follows the word “Ingredients” on the package.
Why the order matters
Ingredients are listed from the highest concentration to the lowest: water, oils and humectants usually come first. After the first five to seven positions come ingredients used in small amounts — actives, preservatives, fragrance. So “niacinamide at the end of the list” and “niacinamide in third place” are two different products, and Skin Profile takes every ingredient's position into account.
Safety is more than a list of “bad” ingredients
The same ingredient can be neutral for one skin and irritating for another. Alcohol near the top dries sensitive skin, essential oils and fragrance are common allergens, and acids and retinoids call for care. The Skin Profile safety score is built on ingredient data and separately flags what matters for your skin type and your allergens.
Effectiveness depends on the product's job
A cream, a serum and a cleanser have different jobs, so they are scored differently. For leave-on care, actives and their position matter; for cleansers, how gentle the surfactants are. Other rinse-off products are not scored for effectiveness yet — no score is more honest than an inaccurate one.
Your bag: how products work together
Even good products can clash: acids and retinoids on the same night, several exfoliants at once, the same active twice. Add your products to your bag — AI conclusions will account for what you already use, and the bag review will suggest the morning and evening order and what is missing, such as sunscreen.
Limits
- The score is built from the ingredient list: brands rarely disclose concentrations.
- Ingredients are recognised from our dictionary; unknown names are shown separately.
- The result is for information only and does not replace a dermatologist.
