PATHOLOGY

Detailed explanation-1: -Sebaceous glands produce an oily substance called sebum and sweat glands produce a watery substance called sweat. Sweat glands have ducts, which are pathways to excrete substances to the surface of your skin. Sebaceous glands secrete sebum through your hair follicles and don’t have ducts.

Detailed explanation-2: -The body produces sebum – a sticky, oily substance made up of various fat molecules and squalene. It does serve a good purpose, but a lot of people don’t like it because it can make their skin appear oily. Sebum is a sticky oily substance the body produces in order to keep the skin moisturised.

Detailed explanation-3: -The sebaceous glands that make sebum are on just about every surface of the body. While sebum is important for skin health, having too much or too little of the oil can lead to acne, oily skin, and chronic itchiness and skin irritation.
