What this is good for
Ingredient stack
Each ingredient is listed in descending concentration. Above the 1% line the order is regulated — below it, brands can list in any order.
Ingredients above the dashed gold line are dosed above 1% (the regulatory threshold) — these are what the formulation is really built on. Percentages are positional estimates from INCI order unless a brand discloses them.

Put this in context
Skin Stacker is independent and receives no payment from any brand. Ingredient analysis is based on publicly disclosed INCI lists and the peer-reviewed literature. Percentages are positional estimates from INCI order unless a brand discloses them. Formulations change — always re-check the label on your specific batch before using.
