Science: Magnesium stearate is widely used in pharmaceutical tablets and cosmetic powders as a processing aid. The provided research confirms its use in tablet formulation at optimal concentrations without safety concerns in that context. Limited peer-reviewed dermatological data exists for topical skincare applications, but it is generally recognized as safe by cosmetic regulatory bodies at typical use levels.
