What does keratosis pilaris mean?

Generally, "maozhi jiaohua" refers to keratosis pilaris. Keratosis pilaris is a skin condition and a hereditary disease caused by excessive keratinization around hair follicles, which affects the growth of fine body hair. The skin becomes rough and, in severe cases, resembles goosebumps.

Keratosis pilaris is strongly related to genetics and results from abnormal keratinization due to autosomal dominant inheritance. In addition to congenital genetic factors, changes in hormone levels, immune system abnormalities, sun damage, and physical trauma may also contribute to the development of this condition. Skin symptoms typically worsen during winter and improve in summer.

The main symptom of keratosis pilaris is abnormal skin keratinization, with keratin plugs blocking the hair follicle openings. In more severe cases, the pores may darken, appearing reddish-brown or brown, and the skin becomes increasingly rough. Each small papule often contains a tightly coiled hair that appears as a tiny black dot. The condition mainly affects cosmetic appearance; occasionally it causes itching, and very rarely leads to follicular pustules.

Patients with keratosis pilaris are advised to eat more vegetables and fruits, exercise regularly, drink plenty of water, avoid spicy and irritating foods, and maintain regular sleep patterns to improve their skin condition. Mild cases can be managed by focusing on skin moisturization and exfoliation. For severe cases, patients should seek medical care and receive treatment under a doctor's guidance.
