As we age, the skin undergoes many changes, including fine lines and wrinkles, pigmentation, laxity and texture. Both intrinsic and extrinsic factors play a vital role in the ageing process where external ageing is mostly attributed to ultraviolet (UV) radiation through the action of free radicals.1 Vitamin C is a powerful ingredient in mitigating these changes.2-4
Vitamin C plays a vital role in the delay of premature skin ageing, decreasing UV-induced sun damage and age spots, promoting collagen synthesis and improving the appearance of fine lines and wrinkles, as well as acne.5 Vitamin C functions as a co-factor for the enzymes prolysyl and lysyl hydroxylase – the enzymes that are responsible for stabilising and cross-linking the collagen molecules. In addition, it stimulates lipid peroxidation, leading to the formation of malondialdehyde, which in turn stimulates collagen gene…
