B3 skin refers to the benefits derived from the topical or supplemental use of niacinamide, a form of vitamin B3. It's not a specific skin type, but rather describes skin that's been treated or improved with this vitamin. Niacinamide offers a multitude of advantages for skin health.
Benefits of B3 for Skin
Numerous studies and expert opinions highlight the positive impact of vitamin B3 on skin:
