👉 Pimples, or acne, arise from various factors including excess sebum production, clogged pores, bacterial infection, and inflammation. The most common types are blackheads (open comedones), whiteheads (closed comedones), and papules or pustules (inflammatory acne). Blackheads form when excess sebum mixes with dead skin cells and bacteria, creating a dark spot. Whiteheads occur when this mixture doesn't fully clog the pore, appearing white or closed. Inflammatory acne involves bacteria like
Propionibacterium acnes
causing redness, swelling, and pus-filled pimples. Understanding these types helps in identifying the underlying causes and selecting appropriate treatments, such as topical retinoids for blackheads or antibiotics for bacterial infections.
