How to use an AHA without irritation

Lactic acid is one of the gentlest AHAs, but even gentle acids need a little respect.

Start slow

Use the AHA Peeling Concentrate once a week for the first two weeks, then move to twice a week if your skin is happy.

Give it its own night

Do not layer it with other strong actives. On AHA evenings, apply to clean skin and leave it on overnight.

Sunscreen, always

Exfoliated skin is more sensitive to the sun. Wear sunscreen the next morning, every time.

Listen to your skin

Tingling that fades is normal. Stinging, redness or flaking means pause and go back to basics for a few days.
