Chicken skin, or keratosis pilaris, is characterized by small pimples centered on hair follicles, usually asymptomatic and sometimes mildly itchy. Keratosis pilaris is characterized by small keratinized or hyperkeratotic papules on the hair follicles, which are rough to the touch, and often occur on the upper arms, thighs, back, and cheeks, and are usually asymptomatic or sometimes mildly itchy. Keratosis pilaris does not cause much damage to the human body, but often affects aesthetics and has a psychological impact on the patient. Patients with Keratosis Pilaris can improve their symptoms by applying topical moisturizers, or use medications that regulate keratinization, such as salicylic acid, retinoic acid ointment, and vitamin A under the guidance of a medical professional, in order to promote keratinization of the skin follicle openings and alleviate symptoms.
