Cosmetic compositions

A method of preparing cosmetic compositions, comprising the steps of:

• a.) providing a polar solvent;
• b.) dissolving a vitamin B3 compound in the polar solvent at an amount greater than the saturation solubility at ambient temperature of the vitamin B3 compound in the polar solvent such that undissolved vitamin B3 compound is present;
• and
• c.) combining the admixture of step b.) with a dermatologically acceptable cosmetic carrier.

A method of improving the skin penetration of vitamin B3 compounds by applying to the skin a safe and effective amount of a cosmetic composition, said composition comprising:

• a) from about 0.01% to about 50%, by weight, of a vitamin B3 compound;
• b) from about 0% to about 90%, by weight, of an emollient component comprising from 0% to about 100%, by weight, of an oil liquid at ambient temperature;
• c) from about 0.01% to about 80%, by weight, of a polar solvent;
• d) from about 0% to about 30%, by weight, of a surfactant;
• e) from about 0% to about 90%, by weight, of a solidifying agent;
• and
• f) from about 0% to about 90%, on an anhydrous basis, of a color wherein the vitamin B3 compound is added to the composition such that the concentration of the vitamin B3 compound will be at least about 50% greater than the saturation solubility of the vitamin B3 compound in the composition at ambient temperature.
