Disclosed herein are cosmetic compositions to support skin metabolism and ameliorate the appearance of aging. Cosmetics such as masks, sunscreens, and lotions are particularly preferred. The compositions contain 0.01-30 % of an antioxidant (preferably R-a-lipoic acid), 0.01-30 % of a carnitine (preferably ALC), and optionally 0.01-15 % of a coenzyme Q (preferably Q10), and/or 0.01-30 % of a creatine. Also disclosed are methods of treatment of aged, photoaged, dry, lined or wrinkled skin. A method of protecting skin from the deleterious effects of sun exposure includes applying a sunscreen composition containing 0.001-10 % antioxidant, 0.001-10 % carnitine, and optionally 0.001-10 % coenzyme Q and/or 0.1-40 % creatine. The antioxidant, a carnitine, and optionally coenzyme Q and/or creatine fight age-related declines in skin mitochondrial function, which result in the appearance of aging.
