Raspberry ketone is a natural compound found in raspberries that is used in cosmetics primarily as a fragrance ingredient. In skincare products, it is marketed for potential skin-firming and antioxidant benefits, though evidence specifically supporting topical skincare use is limited.
Benefits
May provide antioxidant effects when applied topically
Used to add pleasant fragrance to products
Generally well-tolerated in cosmetic formulations at low concentrations
Potential concerns
Safety data for topical use in humans is sparse; most research focuses on oral consumption
High oral doses in animal studies caused serious toxic effects including organ damage and mortality — though topical cosmetic use involves much lower exposure
May cause irritation or sensitivity in some individuals
Science: Published research on raspberry ketone focuses primarily on oral toxicity and weight-loss claims in animal models, showing dose-dependent harmful effects at high doses. Direct evidence for safety and efficacy of topical application in skincare is limited, making assessment of topical cosmetic use challenging.
