👉 Pimples, medically known as acne, are characterized by several key attributes: they typically appear as red, swollen, and often painful bumps on the skin's surface, commonly found on the face, but also on other areas like the chest and back. These lesions can manifest in various forms, including open comedones (blackheads), closed comedones (whiteheads), and inflamed papules and pustules filled with pus. The development of pimples is influenced by factors such as excess sebum production, clogged pores, bacterial infection, and hormonal changes, particularly during adolescence but also in adults. The inflammation and subsequent crusting can lead to scabbing and scarring, making acne a common and often distressing skin condition.
