Is Glycolic Acid Safe for Dark Skin?

How to get the exfoliation benefits without risking hyperpigmentation.

Glycolic acid can be excellent for dark skin — it treats hyperpigmentation, evens skin tone, and improves texture. But melanin-rich skin is more prone to post-inflammatory hyperpigmentation (PIH), so irritation from over-exfoliation can create the exact problem you're trying to solve. The key is using the right concentration, frequency, and always pairing with sunscreen.

Using Glycolic Acid Safely on Dark Skin

Start Low and Slow

Begin with 5-8% glycolic acid, applied 2-3 times per week. Melanin-rich skin reacts more visibly to irritation, so gradual introduction is essential. You can increase to 10% after 4-6 weeks if no irritation occurs.

Sunscreen Is Non-Negotiable

Glycolic acid increases photosensitivity. On dark skin, UV exposure after exfoliation can trigger new hyperpigmentation. Use SPF 30+ daily — even on cloudy days, even when you stay indoors (window UV counts).

Consider Mandelic Acid First

Mandelic acid is an AHA with a larger molecular size — it penetrates slower and more evenly, reducing the risk of irritation-triggered PIH. It is often recommended as the first-choice AHA for darker skin tones.
