Acne is a common skin condition causing pimples, such as whiteheads, blackheads, or inflamed patches, sometimes forming painful cysts. It happens when pores clog with excess oil and dead skin cells, creating plugs called comedones. Whiteheads stay under the skin, while blackheads darken when exposed to air. Bacteria trapped in clogged pores can cause inflammation and pimples, with severe cases leading to nodulocystic acne. Though often linked to teenage hormonal changes, acne can affect all ages and is influenced by genetics.
