Antioxidants neutralise free radicals generated by UV radiation, pollution, and metabolic processes, preventing oxidative damage to skin cells and the product formula itself. Common cosmetic antioxidants include tocopherol (vitamin E), ascorbic acid (vitamin C), BHT, and plant-derived polyphenols.
Relevance for Rosemary Extract: Most antioxidants are well-tolerated, but some — particularly propyl gallate, BHA (butylhydroxyanisole), and certain plant-derived polyphenols — are recognised contact allergens. Vitamin E (tocopherol) allergy, while uncommon, is occasionally identified in patch testing.
