Shop by active form and stated percentage

Know the active you want? Choose its exact form first, then its stated percentage. A bigger number is not a better-product score.

What these numbers mean

17 of 478 product records have a usable named concentration claim here. Products without one are not treated as 0%. This is not a complete catalog of every active present. Sunscreen actives have a separate filter browser.

Percentages are recorded manufacturer claims, not our measurements. Weight/weight, blend composition, delivery, pH and stability are not independently established. Do not compare different derivatives or complex percentages as equivalent potency. Follow the product directions; this is not pregnancy or medical suitability screening.
