Glycolic Acid
An alpha hydroxy acid from sugarcane, water-soluble and small in molecular size, with pH-dependent activity. It's used in leave-on or rinse-off exfoliants to loosen surface buildup, refine texture, and support a more even-looking tone.

Our take
Is Glycolic Acid a Good Ingredient?
It's Good because it's a well-studied AHA that genuinely smooths texture and brightens when used at effective, low-pH levels. Its small molecular size, though, increases sting potential and sun reactivity compared with some other acids, which is the tradeoff that keeps it from Great.
What it does
Skin Benefits
Promotes a smoother, brighter-looking complexion and softens the look of fine lines and rough patches. Helps unclog surface debris so pores appear more refined.
Where you'll find it
Uses in Skincare & Cosmetics
Frequently found in toners, serums, and at-home peels for nighttime resurfacing. Also used in exfoliating cleansers and body lotions for rough areas like elbows or KP-prone skin.
Before you use it
Safety
May cause tingling, redness, or dryness, especially at higher strengths or low pH. It can increase photosensitivity; use with daily sunscreen and consider nighttime application. Patch test and reduce frequency if irritation occurs.
