Platinum

Platinum is a rare, precious metal that appears in cosmetic formulations as a conditioning and protective ingredient. In skincare, it is typically used in very small concentrations and is valued for its stability and inert nature, meaning it is unlikely to react with other ingredients or degrade easily.The ingredient is proposed to work as an antioxidant and antimicrobial agent, though its use in topical skincare remains relatively niche compared to other established actives.

Platinum is believed to function as an antioxidant by donating electrons to unstable free radicals, potentially reducing oxidative stress on skin cells. Its antimicrobial action is thought to stem from its chemical properties, though the exact mechanism in topical skincare formulations requires further investigation.As a skin conditioner, platinum may help smooth and refine the skin's surface texture, though this is largely a cosmetic rather than therapeutic effect.

Platinum is typically incorporated into serums, creams, and masks by manufacturers. If you use a product containing this ingredient, apply it as directed by the product instructions, usually as part of your routine after cleansing and before moisturiser. Because evidence is limited, it is best viewed as a supplementary ingredient rather than a primary active in your skincare strategy.

Platinum is generally considered well-tolerated in topical skincare at the concentrations used in cosmetics. As with any ingredient, those with known sensitivity to metals or a history of contact sensitivity should perform a patch test before wider use.
