What is Magnesium Myristate?
The magnesium salt of myristic acid, used in powder makeup to improve adhesion, slip, and pressability. Common in pressed powders, blushes, and eyeshadows.
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.
