<P> Sebaceous glands are part of the body 's integumentary system and serve to protect the body against germs . Sebaceous glands secrete acids that form the acid mantle . This is a very fine , slightly acidic film on the surface of the skin that acts as a barrier to bacteria , viruses , and other potential contaminants that might penetrate the skin . The pH of the skin is between 4.5 and 6.2 , and this acidity helps to neutralise the primarily alkaline nature of contaminants . </P>
