👉 Pimples, medically known as acne, are small, inflamed bumps on the skin caused by a combination of factors including excess sebum production, clogged pores, bacterial infection, and inflammation. When hair follicles become blocked with dead skin cells and oil, bacteria can thrive, leading to inflammation and the formation of pimples. These can manifest as whiteheads (closed comedones), blackheads (open comedones), or red, painful cysts (nodules). Hormonal changes, genetics, stress, and certain medications can exacerbate acne. Proper skincare, including cleansing, exfoliating, and using non-comedogenic products, can help manage pimples, but severe cases may require medical intervention.
