Compositions containing nicotinamide riboside (NR) are provided. NR containing compositions are used in the care or treatment of skin and skin conditions. In some embodiments, the invention relates to pharmaceutical compositions and cosmetic compositions containing nicotinamide riboside. In further embodiments, the invention relates to methods of using nicotinamide riboside to promote the increase of intracellular levels of nicotinamide adenine dinucleotide (NAD+) in cells and tissues for improving cell and tissue survival. A method of treating signs or symptoms of aging or skin wrinkles in an individual is provided, comprising topically administering to the individual in need of such treatment an effective amount of the compound nicotinamide riboside, or salts thereof.
1. A method for repairing a wound in the skin of an individual, comprising topically administering to the individual in need of such treatment over at least about 24 hours, or more, a therapeutically effective amount of the compound nicotinamide riboside, or a salt thereof, wherein skin cells in the skin have increased motility effecting wound repair.
2. The method of claim 1 , wherein the individual is a human.
3. The method of claim 2 , wherein the nicotinamide riboside compound, or a salt thereof, is provided in a composition comprising a pharmaceutically acceptable carrier.
4. The method of claim 3 , wherein the nicotinamide riboside compound is a salt selected from the group consisting of fluoride, chloride, bromide, iodide, formate, acetate, ascorbate, benzoate, carbonate, citrate, carbamate, formate, gluconate, lactate, methyl bromide, methyl sulfate, nitrate, phosphate, diphosphate, succinate, sulfate, and trifluoroacetate.
5. The method of claim 4 , wherein the nicotinamide riboside compound is a chloride salt.
6. The method of claim 3 , wherein the therapeutically effective amount of nicotinamide riboside compound, or a salt thereof, for a total dose is in a range of about 0.01% by weight to about 50% by weight based on the total weight of the composition; and wherein the wound repair is substantially effected.
