Ingredient comparisons

Two that do the same job. Which is yours?

When two ingredients chase the same goal, the label rarely tells you which to pick. Each page below puts a pair side by side, honestly, and helps you choose by your skin. Want to use two together instead? See if they mix.

Actives 258

Retinoids, vitamin C forms and the other workhorses. Same job, different trade-offs.

Hydrators 78

Humectants that pull water into the skin. Closer than the marketing suggests.
