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 Bcompound 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 pH buffer comprising lactic acid and sodium lactate, a polymer thickener comprising polyacrylate crosspolymer-6, and 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.

Low pH skin care composition and methods of using the same

Disclosed is a method of improving the penetration of a vitamin Bcompound 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 Bcompound. The second skin care composition applied to the skin is a conventional skin care composition that contains a higher concentration of the vitamin Bcompound than the first composition. When applied in the proper sequence, the regimen results in an unexpectedly high vitamin Bflux into the skin.

Method of improving penetration of a vitamin B3 compound into skin

The present disclosure generally relates to a skin care composition for providing ultraviolet (UV) protection to skin with desired sensory feels by the consumers. More specifically, the present disclosure relates to a UV-blocking skin care composition having both proper stringiness and proper viscosity.
