  • Method of improving penetration of a vitamin B3 compound into skin
    Patent number: 11583488
    Abstract: Disclosed is a method of improving the penetration of a vitamin B3 compound into skin. The method involves a skin care regimen in which at least two skin care compositions are used in sequence to treat a target portion of skin where a skin health or appearance benefit is desired. The first composition applied to the skin is a low-pH skin care composition that contains a first concentration of a vitamin B3 compound. The second skin care composition applied to the skin is a conventional skin care composition that contains a higher concentration of the vitamin B3 compound than the first composition. When applied in the proper sequence, the regimen results in an unexpectedly high vitamin B3 flux into the skin.
