An AHA exfoliant is a leave-on or rinse-off product formulated with alpha hydroxy acids like glycolic or lactic acid, designed to dissolve the bonds between dead skin cells and reveal smoother, brighter skin.

AHA exfoliants dissolve cell bonds chemically for even, controlled resurfacing, while physical scrubs manually buff the surface and can be harsher or more uneven on sensitive skin.

Start with a mild, lower-percentage formula and limited frequency, building up strength and use only as your skin shows it tolerates the current step well.

Not on the same night for most people; alternating nights lets each active work without compounding irritation.

Persistent redness, stinging, burning or peeling beyond mild, brief flaking are signs to scale back frequency or move to a milder formula.

By speeding surface cell turnover, regular AHA exfoliant use can help fade the look of post-acne marks and uneven texture over time.

Yes, when introduced gradually and used at the frequency recommended for your skin's tolerance; start less often and increase slowly.

Yes, always. AHA-exfoliated skin is significantly more sensitive to UV, making daily broad-spectrum SPF 30+ essential.

Some cleanse-and-treat gels are gentle enough for daily use, but it depends on the formula's strength; start a few times a week and adjust based on how skin responds.

Avoid layering with retinol, vitamin C, or other strong acids on the same night, and skip physical scrubs on the same day to limit over-exfoliation.

Some improvement in texture and radiance can appear within a couple of weeks, though full results for tone and fine lines typically take 6 to 12 weeks of consistent use.

It guarantees fresh, authentic, properly stored acid concentrations, so the formula performs and feels exactly as the brand intended.
