The American Academy of Dermatology (AAD) and the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) offer detailed descriptions of acne:
Acne encompasses pimples, deeper lumps (cysts or nodules), and plugged pores (blackheads and whiteheads) affecting various body areas like the face, neck, chest, back, shoulders, and upper arms. It typically initiates during puberty but can persist into adulthood. Key factors contributing to acne include overproduction of oil by enlarged oil glands, blockage of hair follicles releasing oil, and bacterial growth, specifically P. acnes.
Various pimple types include whiteheads, blackheads, papules, pustules, nodules, and cysts, each presenting distinct characteristics and severity.
Acne affects people of all races and ages but is most prevalent among teenagers and young adults. Hormonal changes, heredity, certain medications, and greasy makeup can exacerbate acne.
Proper skincare for acne involves gentle cleansing, avoiding skin contact, careful shaving, sun protection, and selecting non-comedogenic makeup. Additionally, regular shampooing is recommended for oily hair.
Factors exacerbating acne include hormonal fluctuations, pressure on the skin, environmental conditions like pollution and humidity, and skin irritation from squeezing or scrubbing.
