What is Colloidal Oatmeal?
Finely milled whole oats, an FDA-recognized skin protectant for itch and irritation. Its starches and beta-glucans soothe and lightly moisturize in eczema creams, oat cleansers, and sensitive-skin lotions.
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.
