👉 Pimples, or acne, are a common skin condition resulting from the clogging and inflammation of hair follicles and sweat glands. When excess sebum (oil) from the skin mixes with dead skin cells, bacteria, and other impurities, it can lead to the formation of comedones (blackheads or whiteheads). If these clogged pores become infected, they can progress to papules (small, red bumps), pustules (pimples with pus), nodules (larger, painful lumps beneath the skin), or cysts (deep, inflamed lesions). These processes are influenced by hormonal changes, genetics, and environmental factors, making pimples a multifaceted skin issue that requires understanding of both internal and external triggers.
