The acid mantle is a very fine, slightly acidic film (with pH value of 5.3-5.5) on the surface of human skin acting as a barrier to bacteria, viruses and other potential contaminants that might penetrate the skin. Sebum is secreted by the sebaceous gland and when mixed with sweat becomes the acid mantle
