👉 Average pimples, or comedones, are small, round bumps on the skin caused by clogged hair follicles. They occur when excess oil (sebum) mixes with dead skin cells, leading to blockages. These blockages can result in two main types: open comedones (blackheads), where the clog remains on the surface of the skin and turns dark due to oxidation, and closed comedones (whiteheads), where the clog is sealed beneath the skin's surface. Factors like hormonal changes, genetics, diet, and hygiene can influence their frequency. While most pimples are harmless, persistent acne can indicate underlying skin issues and may require professional treatment.
