Vitamin C, also known as L-ascorbic acid is a nutrient and antioxidant with many benefits for skin, hair and body functions including the synthesis of collagen. Vitamin C can be synthetically derived or naturally occurring in citrus fruits and is scientifically proven to repair and build skin tissue. In particular this antioxidant is known for its ability to target and improve the visible signs of ageing, including wrinkles, laxity and discolouration. This water soluble molecule can neutralise free radicals, helping prevent against the damage free radicals cause, and also fight against oxidative stress. Unlike other vitamins, Vitamin C is not naturally occurring in the human body, meaning it must be acquired through external sources, including food, supplements, and topical applications, such as a vitamin c serum.
