How Vitamin B3 Acts On Your Skin?

There are 2 important enzymes (NADH and NADPH) that contribute to the production of cellular energy and lipids (responsible for cell growth). With a sufficient supply of both enzymes, your skin creates an effective barrier to external factors that influence the aging process. However, the levels of both NADH and NADPH decline as we grow older.

 When applied topically, vitamin B3 seems to reduce their rate of decline.
Because topical application of niacinamide can help preserve levels of NADH and NADPH, it contributes to the support of the skin’s barrier against pollutants and other irritants.

 Therefore, many skin conditions, such as acne, the redness associated with rosacea, and other inflammatory signs can be actively managed. Also, vitamin B3 has shown to be useful for encouraging the production of natural emollients that can help the skin remain hydrated. It also helps in lightening the complexion of your skin.

Foods rich in vitamin B3-

Fortified bread and cereals
Red fish 
Yeast extract spread.
Roasted turkey breast.

Vitamin b3 is now being used as a potent ingredient in a variety of cosmetic products. Hence, while buying any skin care product look out for the ingredient list and select a product which contains vitamin B3 for a perfect healthy complexion :) :)
