Diamond Powder Poco recomendable Exfoliante No known benefits Diamond Powder at a glance Abrasive mineral (technically a crystallized modification of carbon) Used in skin care products such as exfoliating cleansers where it provides buffing/scrubbing action May cause micro tears in skin due to the irregular shape of the particles Research supporting diamond powder’s use in cosmetics is lacking Diamond Powder description Diamond powder is an abrasive mineral (technically a crystallized modification of carbon) used in skin care products such as exfoliating cleansers where it provides a buffing/scrubbing action. While some suppliers of this ingredient claim it improves skin’s complexion and circulation, in reality harsh abrasives have a detrimental effect on skin’s barrier due to the micro tears caused by the irregular, often jagged shape of particles. That said, it’s possible that diamond powder could be incorporated into emulsions in such a way that the abrasiveness is minimized. If you test the formula containing diamond powder against skin and don’t feel any scratchiness as it is gently rubbed in, then there isn’t cause for concern. Regardless, research supporting diamond powder’s use in cosmetics is lacking. There’s nothing “premium” about seeing this powder in skin care or makeup, although it’s often marketed as such.
