acne vulgaris: Definition, Uses, and Clinical Overview
acne vulgaris is a common inflammatory skin condition that affects the pilosebaceous unit (hair follicle and oil gland). It typically appears as blackheads, whiteheads, pimples, and sometimes deeper painful nodules. It is widely discussed in cosmetic medicine because it can affect facial appearance and confidence. It is also relevant in reconstructive and procedural dermatology because it can lead to scarring that may be treated with resurfacing or scar procedures.
