The invention provides a beverage composition comprising hydrolyzed collagen and vitamin C, or a derivative thereof, which is particularly suitable for improving skin hydration and skin condition. Additional active ingredients may include methyl sulphonyl methane, a vitamin selected from the vitamin B complex, L-lysine, omega-3 and omega-6 fatty acids. The beverage composition is such that it promotes higher absorption and bioavailability of skin-nourishing ingredients. The beverage composition can improve the moisture content of the skin and can prevent fine lines and wrinkles.
