What a —/5 rating means
Because no dependable rating exists, judge Magnesium Myristate by how your own skin responds rather than by a number. The absence of a score is not the same as a zero — it simply means the ingredient has not been reliably tested on the classic comedogenic scale.
About Magnesium Myristate
It is a mineral-based ingredient, common in pigments and sun protection. A metallic soap of myristic acid used as a binder and slip agent in pressed powders, blushes and eyeshadows. It is named on the CLEARSTEM and AcneClinicNYC pore-clogging ingredient lists, but neither publishes a 0-5 comedogenic score for it and no Fulton-derived table we cite carries one. We therefore leave it unrated rather than invent a number — treat the listing itself as the signal.
Magnesium Myristate in makeup and skincare
It is central to mineral makeup, pressed powders, and mineral sunscreens.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Magnesium Myristate is among the fatty-acid or ester-type ingredients that community sources commonly avoid — a separate concern from its comedogenic score, and one with weaker evidence behind it.
