What it is
Platinum in cosmetics generally refers to the noble metal in colloidal or finely divided form dispersed in a product. It is used at very low levels and is featured mainly as a premium marketing ingredient associated with a conditioning claim. It does not contribute UV protection and is a minor formulation component.
Safety & warnings
Platinum in colloidal cosmetic use is present at trace levels and is generally inert. Some individuals can be sensitized to certain platinum compounds, so users with known metal sensitivities may wish to take care, though reactions to colloidal platinum in finished cosmetics are uncommon.
Origin & sourcing
Platinum is a naturally occurring noble metal; the cosmetic ingredient is the refined elemental metal, typically dispersed as colloidal particles.
