FUNCTIONS OF VITAMIN C
Promotes collagen synthesis(1)
Collagen production starts to decrease by 1% per year(2), especially from
mid-20s.(4) Vitamin C, as one of the vital components required in the human body, helps promote collagen synthesis to further fight off signs of aging whilst also stimulating collagen production for firmer-looking skin from the inside out.
