L-ascorbic acid helps the skin in three different ways and they all have to do with the metabolism of the skin cells. The skin metabolizes by exfoliating and repairing itself as well as by rejuvenating collagen fibers, which helps create tighter skin.
L-ascorbic acid helps slow the production of melanin, which prevents dark spots on face which can be caused by pregnancy, hormonal changes from taking birth control pills, and through the natural process of aging. L-ascorbic acid may also slow the development of skin cancer because it works as an anti-oxidant and can reduce skin damage on a cellular level. Another benefit of this ingredient is that it encourages collagen development so that skin can look and feel firm, and may even get rid of wrinkles in some cases.
