What it does

Mandelic acid is a large-molecule alpha hydroxy acid that exfoliates the skin by breaking down the bonds between dead skin cells. Its slower penetration rate and larger molecular size make it gentler than glycolic acid while still promoting cell turnover. It's particularly valued for sensitive and reactive skin types.

How to use

Be careful pairing with

Other strong exfoliants (glycolic, salicylic) on same day, Vitamin C (may reduce efficacy)

Safety & cautions

Start at low concentrations (5–10%) and use 2–3 times weekly to assess tolerance. Discontinue if persistent irritation occurs and always use SPF 30+ during the day, as exfoliants increase sun sensitivity.
