NIACINAMIDE: Niacinamide (NNA) is the active form of Vitamin B3. A safe vitamin found in foods and cosmetics. Research shows niacinamide can offer a number of benefits in improving the appearance of aged and photodamaged skin and improve skin moisturization.
It has been shown to stimulate collagen synthesis and production of ceramide, a lipid compound that contributes to the functional and structural integrity of the skin barrier. Theoretically, by improving barrier integrity, niacinamide may help the skin become more resistant to external irritants.
Topical use of niacinamide has been shown in clinical studies to effectively reduce the rate of sebum excretion and its casual serum levels.
