Detailed answer

Blackheads, also known as open comedones, are formed when the opening of a hair follicle becomes clogged with a mixture of excess sebum, dead skin cells, and bacteria. This accumulation oxidizes upon exposure to air, giving blackheads their characteristic dark color. Factors that contribute to the development of blackheads include hormonal changes, excessive sebum production, certain medications, and using heavy or pore-clogging skincare products. Additionally, poor skincare habits such as infrequent cleansing or inadequate exfoliation can lead to the buildup of impurities and the formation of blackheads. It is important to adopt a regular cleansing routine, avoid pore-clogging products, and utilize exfoliants to prevent and manage blackheads.
