What's actually doing the work

Lactic Acid
AHA / Alpha Hydroxy Acid (milk-derived)
Acid
The gentlest commonly used AHA — larger molecular weight than glycolic means shallower penetration and less irritation. Uniquely dual-function: exfoliates dead skin AND acts as a humectant, hydrating while it treats. Ideal first AHA for sensitive skin. At higher concentrations treats hyperpigmentation and used in professional peels.
