The acid mantle is a very fine, slightly acidic film on the surface of the skin acting as a barrier to bacteria, viruses and other potential contaminants that might penetrate the skin.[1] It is secreted by sebaceous glands. The pH of the skin is between 4.5 and 6.2, so it is acidic.[2] These contaminants and other chemicals are primarily alkaline in nature and the skin's moderate acidity helps to neutralize their chemical effects.
