What are blackheads?

Blackheads are a common skin condition primarily caused by excessive sebum production from sebaceous glands, which leads to clogged hair follicles that then oxidize upon exposure to air, forming blackheads. They typically occur at the opening of hair follicles, forming dark or grayish-black comedones. Blackheads are commonly seen in adolescents during puberty and frequently appear on the face, chest, and back, particularly on the nose where blackheads are most prevalent. The occurrence of blackheads is closely related to individual skin type and external environmental factors (such as high temperature, diet, irregular作息, and high psychological stress). Treatment options for blackheads include topical ointments, oral medications, chemical peels with fruit acids, and it is also important to maintain good facial hygiene and healthy lifestyle habits. If necessary, it is recommended to consult a doctor.
