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 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.
