Commonly known as Vitamin B3, Niacinamide at 2% has been shown to reduce water loss in the skin and retain fatty acid levels (younger, plumper, firmer skin).
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.
