Glycolic Acid for Acne (Acne Vulgaris)

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 Acne (Acne Vulgaris)

Exfoliates the surface and loosens the dead skin that blocks pore openings. It is an AHA (alpha-hydroxy acid) and the smallest one, so it sinks in easily. Trials of 10-15% peels show real improvement in clogged pores and mild pimples over a 12-week course, and at-home strengths (5-10%) keep up the progress. It is especially handy for blackheads, whiteheads, and the dark marks left behind. Do not use it the same night as a retinoid (together they can over-irritate).

How Glycolic Acid works

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