Glycolic Cleanser

After 40, skin cell turnover slows. This speeds the exit.

Dull skin usually isn't dry — it's covered in dead cells that used to shed on their own and now don't.

Glycolic acid is the smallest alpha-hydroxy acid, which is why it works: it loosens the bonds holding dull surface cells in place so they rinse away instead of sitting there. With glycerin and vitamin E so it exfoliates without stripping. No soap, no dyes, no alcohol.

How to use: morning and night. New to acids? Start once daily and build. Follow with sunscreen in the morning. Best for: dullness, rough texture, and anyone whose skin stopped looking bright.
