  • Method of Improving Penetration of a Vitamin B3 Compound into Skin
    Publication number: 20210369588
    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.

  • Low pH Skin Care Composition and Methods of Using the Same
    Publication number: 20210369589
    Abstract: Disclosed is an efficacious, low-pH skin care composition that provides good sensory properties and has a low skin irritation potential. The low-pH composition includes an effective amount of a vitamin B3 compound and, optionally, one or more additional skin care actives to provide a skin health and/or appearance benefit. The low-pH composition also includes a salt/acid pH buffer system, an acid tolerant polymeric thickener and, optionally, a silicone fluid having a kinematic viscosity of 100 cSt or less at 25° C. The pH of the low-pH composition can range from 2.0 to 5.0.
