MICROANATOMY

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. Sebaceous glands can clog, so you can keep your glands healthy by following a skin care routine that includes cleansing and moisturizing your skin.

Detailed explanation-2: -Sebum, composed of fats, helps lock moisture into the skin and it helps protect the skin from UV radiation. It even helps repel certain bacteria, protecting you and your skin from infection. Sebum holds onto moisture and keeps skin hydrated and flexible.

Detailed explanation-3: -The sebaceous glands produce sebum through holocrine secretion, a process of programmed cell death. Specialized cells, called sebocytes, dissolve and release sebum into the sebaceous glands. Sebum travels through the follicular duct that connects the sebaceous gland to the hair follicle.
