Exfoliant

Glycolic Acid

Also known as AHA, alpha hydroxy acid

The smallest alpha hydroxy acid, so it works quickly to loosen dull surface cells for smoother, brighter-looking skin.

What is glycolic acid?

Glycolic acid is an alpha hydroxy acid (AHA) that comes from sugar cane. Its small molecule size lets it work quickly on the skin's surface, dissolving the bonds that hold dull, dead cells in place.

What it does for your skin

  • Smooths rough texture
  • Brightens the look of dull skin
  • Helps keep pores clear when paired with acne treatments

How to use it

In our Acne Spot Treatment, glycolic acid supports benzoyl peroxide by helping keep the surface of the skin clear. Use it as directed and follow with a moisturizer if your skin feels dry.

Who it's for

Normal, oily and breakout-prone skin. Dry or sensitive skin may prefer lactic acid, which is gentler.

Common questions

What is the difference between glycolic acid and salicylic acid?
Glycolic acid works on the skin surface. Salicylic acid is oil-soluble and works inside the pore.
Do I need sunscreen with glycolic acid?
Yes. AHAs can make skin more sensitive to the sun.
