Keratosis pilaris manifests as small pimples at the hair follicles and usually requires no special treatment. If it affects the aesthetics or causes discomfort, intervention can be made through oral medication, topical medication, and physical therapy. 1. Topical medications (1) Medications: Ointments such as retinoic acid, tazarotene, and urea can be chosen to soften or dissolve keratinized hair follicles and alleviate pimples and other symptoms. If there is severe redness, swelling and other inflammatory reactions, topical glucocorticoids such as dexamethasone cream can be used. (2) Precautions: Discontinuation of the drug is recommended if adverse reactions such as localized pain, itching, redness, or swelling occur after use. Children are not recommended to use retinoic acid; retinoic acid, tazarotene, dexamethasone and other drugs are prohibited during pregnancy and lactation. 2. Oral drugs: including vitamin A, E vitamin supplements. However, it should be noted that during pregnancy, breastfeeding, children need to be used with caution. 3. Physical therapy: carbon dioxide laser, pulsed dye laser and photodynamic therapy can improve the symptoms to some extent. It is necessary to use drugs under the guidance of clinicians, and unauthorized use of drugs is prohibited.
