B Vitamins

Panthenol (provitamin B5) is the stable analog of pantothenic acid that has been used in skin care, nail products, and most especially in hair products through its enhanced moisturization benefits. Pantothenic acid enhances wound healing through cell proliferation and protein synthesis and quickly penetrates the skin. Known for its moisturizing and soothing effects, it can play a role in anti-aging skin care through its enhanced cell proliferation and healing abilities [52, 53].

Nicotinamide (niacinamide) is another B vitamin that has entered the skin care arena.Most studies of this vitamin have focused on the anti-inflammatory effects of nicotinamide and its benefit in acne treatment. The role of nicotinamide as a potential anti-aging ingredient has yet to be explored; however, one possible role is in the biosynthesis of ceramides and other stratum corneum lipids [54].
