Lactic Acid
Depends on dose
AHA · Lactic
A larger AHA than glycolic, so it works more slowly and gently, and it's also a humectant.

- Our take
- The AHA we'd point a teenager at first if they want one. It exfoliates and hydrates at the same time, which makes it much harder to overdo than glycolic. Same sun-sensitivity rule applies.

- 5-12%
- Suitable from
- Young adult, 20+ · Middle aged, 40+
- Best for
- Dark marks & dullness · Dryness & hydration · Aging & firmness
