About

Elemental magnesium metal — flammable as a fine powder and not directly used on skin. Cosmetic ingredients are usually magnesium salts; exact INCI raises a flag for context.

Skin benefits

  • Source of magnesium ion in some salts
  • Used as a reducing/processing material
  • Trace mineral in skincare blends

Known concerns

  • Elemental magnesium metal is reactive — flammable in fine powder
  • GHS flammable solid hazard
  • Cosmetic relevance is the salt forms, not the metal
  • Inhalation/dust hazards in handling
