👉 Acute pimples, also known as acne vulgaris, are inflamed or infected hair follicles and pores that appear suddenly, typically within 24 to 48 hours. They result from a combination of factors including excess sebum production, clogged pores due to dead skin cells and bacteria, and inflammation caused by an immune response. When these elements converge, they lead to the formation of red, swollen, and sometimes painful bumps on the skin's surface. The most common types are blackheads, whiteheads, and papules or pustules, which can leave scars if not treated promptly.
