Acne is a common skin condition characterized by the presence of pimples, blackheads, whiteheads, and often inflammation. It typically occurs when hair follicles become clogged with oil and dead skin cells, leading to the growth of bacteria and later inflammation. Acne can appear on various parts of the body, most commonly the face, neck, chest, and back. Factors such as hormonal changes, genetics, stress, and certain medications can contribute to acne development. Treatment usually involves creams or gels, oral medications, and skincare routines aimed at reducing oil production, unclogging pores, and preventing bacterial growth.
