What should you know about Peter Thomas Roth glycolic?

Glycolic acid is an alpha hydroxy acid, or AHA. It works at the skin surface and can make roughness, dullness, and some uneven pigment appear less prominent over time. It does not treat every cause of discoloration or replace assessment of a suspicious spot.

Because exfoliation can temporarily weaken the skin barrier, dryness, tingling, redness, or peeling may occur. Stronger formulas and professional treatments have different risks and should not be treated as interchangeable with home care. Learn more about [Glycolic Acid](/materials/glycolic-acid/).

Follow the package directions and begin with a limited application rather than layering several exfoliants. Keep it away from eyes, lips, cuts, and eczema flares. Moisturise after use and protect exposed skin from sunlight. Do not apply immediately after shaving or over skin that is already burning.

A clinician can help decide whether a professional [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) is appropriate, especially if home products have caused repeated irritation.

Stop the product and seek advice for intense burning, swelling, blisters, hives, or redness that keeps spreading. A new, changing, bleeding, or crusted pigmented lesion needs examination rather than repeated exfoliation.

Ask which strength and schedule suit your barrier, whether glycolic acid conflicts with another product you use, and how to distinguish expected mild peeling from a chemical burn.
