Glycolic Acid for Sun Damage (Photoaging)

Exfoliates the surface of your skin to smooth rough texture and fade dullness. The strongest of the AHAs, so start slow.

Why it works for Sun Damage (Photoaging)

An exfoliating acid (an AHA). At low strengths (5 to 10 percent) it loosens the bonds between dead surface cells so the sun-damaged, pigment-heavy ones shed faster. At the higher strengths used in professional peels (20 to 70 percent) it spurs new collagen and helps reverse the leathery look of sun-damaged skin. Trials show smoother texture and fewer fine lines with regular use. It makes skin more sensitive to the sun, so sunscreen is a must. Use at night.

How Glycolic Acid works

Smallest alpha hydroxy acid; loosens corneocyte bonds in the stratum corneum to accelerate desquamation.
