GENERAL HISTOLOGY

Detailed explanation-1: -Acne is a disorder of the hair follicles and sebaceous glands that become clogged. This leads to pimples and cysts. Acne is a common condition that usually begins during puberty because of hormonal changes.

Detailed explanation-2: -Acne is localized in regions where sebaceous glands are found intensively including mainly the face, back, chest and shoulders. The initial lesions are blackheads.

Detailed explanation-3: -Sebaceous glands secrete an oily substance called sebum. This helps protect the skin from the outside environment. Due to an overgrowth of oil-producing cells, sebum can become trapped inside the gland, causing it to swell and form a bump under the skin. This is known as sebaceous hyperplasia.

Detailed explanation-4: -What Causes Acne? Acne is caused by overactive oil glands in the skin and a buildup of oil, dead skin cells, and bacteria, which leads to inflammation (swelling and redness) in the pores. Oil glands get stimulated when hormones become active during puberty. That’s why people are likely to get acne in their teens.
