What is Zinc Oxide?

A mineral UV filter that covers both UVA and UVB, and doubles as a mild anti-inflammatory (it's the active in diaper rash creams). It's the default filter in sunscreens marketed for sensitive and acne-prone skin. The white cast and thick feel come from the mineral, not from anything pore-clogging.

What to do if you're acne-prone

This ingredient is safe for acne-prone skin from a pore-clogging standpoint. One safe ingredient doesn't clear a whole formula, though: check the rest of the label, because cloggers usually hide mid-list among ingredients like this one.

Where this rating comes from

Our ratings consolidate two lineages: the original rabbit-ear comedogenicity assays published by James Fulton and colleagues (Fulton, Pay & Fulton, Journal of the American Academy of Dermatology, 1984; Fulton, Journal of the Society of Cosmetic Chemists, 1989), and the pore-clogger lists maintained by acne-specialist estheticians in the Face Reality lineage. This ingredient rates 0–1 across those sources (or doesn't appear on the flagged lists at all), which is why our checker doesn't flag it.

Comedogenicity ratings come from published ingredient studies and esthetician-compiled lists. They are imperfect and formulation-dependent, and this page isn't medical advice. Reactions vary by skin, concentration, and the rest of the formula.
