What is Myristic Acid?

A saturated fatty acid found naturally in coconut and palm kernel oil. In cleansers it's combined with alkalis to create rich lather, and in creams it acts as an emulsifier and thickener — so it appears in face washes, shaving foams, and lotions.

What to do if you're acne-prone

Position matters: high on the ingredient list means more of it in the formula. If you're very breakout-prone, choose an alternative; otherwise watch how your skin responds.

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 that refine those assays with decades of client observation. This ingredient appears across both lineages with ratings that vary by about one point; we show the consensus value.

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.
