nary breadth and history of cutaneous ben-
efits. It is thought that its fundamental role as
a precursor of reduced nicotinamide coen-
zymes such as NADH and NADPH is pivotal
to its observed effects. It displays distinct
advantages over other ingredients with sim-
ilar benefits, such as retinol, in that it is well
tolerated, and is not subject to oxidation or
photolysis. In short, the multiplicity of effects
and formulation benefits seen with niacin-
amide make it an ideal choice for a variety of
cosmetic products targeting young and old
skin alike.
