This unique gel formulation, delivers the salicylic acid and lactic acid through a continuous release, allowing deeper penetration, and longer action whilst simultaneously protecting the surrounding skin. The gel is packaged in an easy to use nozzle tube for direct application and consistent release. Each 1 g of the gel contains 167g of lactic acid & 167 g of salicylic acid. When applied onto the skin the salicylic acid acts by achieving a slow, painless destruction of the thickened upper layer of skin. The other active ingredient, lactic acid enhances the activity of salicylic acid as well as having antiseptic properties.
