Detailed explanation-1: -Sebaceous glands are microscopic glands found in your hair follicles that secrete sebum. Sebum is an oily substance that protects your skin from drying out.
Detailed explanation-2: -Sebaceous glands secrete the oily, waxy substance called sebum (Latin: fat, tallow) that is made of triglycerides, wax esters, squalene, and metabolites of fat-producing cells. Sebum lubricates the skin and hair of mammals.
Detailed explanation-3: -Overview. Each pore on the surface of the skin is an opening to a canal called a follicle. The follicle also contains a hair and an oil gland (sebaceous gland). The oil gland helps remove old skin cells, keeps the skin lubricated, and prevents drying of tissues.
Detailed explanation-4: -Sebaceous glands secrete acids that form the acid mantle, a fine, slightly acidic (between pH 4.5 and pH 6.0) film on the surface of the skin that provides a barrier against pathogens, such as bacteria and viruses that might penetrate the skin and are primarily of alkaline nature.
