Sunscreen for Skin on Strong Actives (AHAs, BHAs, Retinoids)
Protecting a routine built on exfoliation.
AHAs can increase the skin's sensitivity to UV; the FDA advises using sun protection and limiting sun exposure while using AHA products and for a week afterward.
Dermatologists frame it simply: exfoliating acids and retinoids speed cell turnover and thin the outer dead-cell layer, so consistent daily sunscreen is non-negotiable while you use them.
Questions we get a lot
Do AHAs, BHAs and retinoids make my skin more sensitive to the sun?
Exfoliating acids and retinoids accelerate cell turnover and thin the outer dead-cell layer, which can leave skin more vulnerable to UV. The FDA specifically advises sun protection while using AHA products and for a week afterward. Use a broad-spectrum SPF 30+ every morning, and apply your actives at night.
Why does my sunscreen sting more when I'm using actives?
Actives can temporarily compromise the barrier, so fragrance or some chemical filters that you tolerated before may suddenly sting. Switch to a fragrance-free mineral formula, patch-test on the inner arm for a few days, and simplify your routine while skin recovers. Persistent reactions warrant a dermatologist.
What sunscreen is best for skin on retinoids or exfoliating acids?
Prioritize a gentle, fragrance-free broad-spectrum SPF 30+; many people on actives find barrier-supporting mineral (zinc oxide/titanium dioxide) formulas easiest to tolerate. The best one is whichever you'll apply generously every single day. Patch-test new products before adding them to an already-active routine.
