Also known as vitamin B3 and nicotinic acid, niacinamide is a potent cell-communicating ingredient that offers multiple benefits for aging skin. Assuming skin is being protected from sun exposure, niacinamide can improve skin’s elasticity, dramatically enhance its barrier function, help erase discolorations, and revive skin’s healthy tone and texture. [1,2,3,4,5,6]
Topically applied niacinamide has been shown to increase ceramide and free fatty acid levels in skin, prevent skin from losing water content, and stimulate microcirculation in the dermis. It also has a growing reputation for being able to treat an uneven skin tone and to mitigate acne and the red marks it leaves behind (known as post-inflammatory hyperpigmentation). Niacinamide, an excellent ingredient for those struggling with wrinkles and breakouts, is stable in the presence of heat and light. [1,2,3,4,5,6]
