Goose bumps on the body, when more prominent, may be caused by keratosis pilaris, which can be removed by temporary observation, topical medication and laser treatment. 1. Temporary observation: Because this disease is benign and does not affect health, most patients do not need treatment and can be temporarily observed. 2. Topical medication: patients can use topical preparations such as Vitamin A acid, urea cream, salicylic acid, etc., which can play a role in moisturizing and dissolving keratin, thus promoting the renewal of the surface skin and facilitating the alleviation of perifollicular keratosis. Serious cases can be treated with oral vitamin A, vitamin E or vitamin A acid drugs. 3. Laser treatment: For patients with more severe keratosis pilaris, if the above treatments are not effective, the doctor may suggest using laser to relieve the symptoms, but multiple sessions are needed to see the results. Keratosis pilaris has a high incidence and often begins in childhood, with lesions worsening significantly during puberty and resolving in adulthood. It is recommended to use medication under the guidance of a doctor and not blindly on your own to avoid adverse effects.
