The right protection : your skin's protective layer
The skin's barrier function is performed primarily by the horny layer of the epidermis and the hydrolipid film finely distributed over the skin's surface. Perspiration, sebum and the horny layer together have a slightly acid pH value of 5.5. The acid barrier maintains the ecological balance of the skin : the acid environment and specially-adapted micro-organisms ward off bacteria. Moreover, the pH value assures and especially permeable arrangement of lipids in the horny layer.
