Effectiveness of Vitamin C
Vitamin C prevents the aging of the skin from the stress by
effectively reducing the free oxygen radicals. It protects and recovers the
damaged skin cell due to UV rays by antioxidant function.
One of the main functions of Vitamin C is whitening. Vitamin C inhibits
the melanin formation and recovers the oxidized melanin to brighten the
skin and prevents dehydration. It also helps in soothing the sensitive
skin and stabilizes and promotes the formation of collagen which is the
main component for hydration and elasticity. At the end, Vitamin C can
help maintaining the elastic and healthy looking skin without wrinkles.
