This form of vitamin B3 can reduce inflammation, fortify the skin barrier, improve skin texture, and improve discoloration. It works by strengthening the top layer of skin, improving the quality and thickness of skin, and protecting against transepidermal water loss (TEWL). It has also been shown to fade existing discoloration and can also reduce future discoloration by inhibiting the movement of melanin to the surface of the skin.
