Detailed answer

Blackheads are caused by clogged hair follicles with a mixture of sebum, dead skin cells, and bacteria. The clog is open to air, which oxidizes the mixture and turns it black. Unlike whiteheads, which are closed comedones, blackheads are open comedones. The only way to remove blackheads is by physically extracting them or using targeted skincare products that help dissolve the clog and unclog the pores. Without proper intervention, blackheads can persist for a prolonged period and may lead to other skin issues like acne. Regular cleansing, exfoliation, and using non-comedogenic products can help prevent the formation of blackheads.
