What It Is
Acne: Acne, also known as acne vulgaris, is a long-term skin condition that occurs when dead skin cells and sebum clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to lack of confidence, anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide.
Why It Happens
Acne arises due to factors affecting the Integumentary System (Skin). Skin conditions arise from immune-mediated inflammation, infections, allergen exposure, UV damage, or disruptions in the skin barrier. While individual cases vary, a combination of genetic susceptibility, lifestyle factors, and environmental exposures typically contribute to the development of Acne.
