Small bumps on the skin that look like chicken skin are more likely to be considered as perifollicular keratosis, or eczema and other diseases. The cause of perifollicular keratosis is not yet clear. It may be related to heredity, metabolism, etc. It is difficult to cure completely, but the symptoms can be improved with medication. The incidence of the disease is increased in children if either the father or the mother has the disease. Usually, children develop the symptoms associated with the disease after the hair follicles have developed. Improvement of symptoms should be done under the supervision of a doctor. Topical applications such as retinoic acid cream or salicylic acid ointment can be used. Eczema is a chronic inflammatory disease caused by internal and external factors, which can be manifested as erythema, papules, pimples, etc., and can cause chicken skin-like bumps on the skin. It can be treated with topical glucocorticoid ointment (e.g., dexamethasone ointment, etc.) and oral antihistamines (e.g., loratadine, cetirizine, etc.). It is recommended that patients with chicken skin-like bumps go to the dermatology department of a regular hospital in a timely manner to get a clear diagnosis and standardize the use of medication under the guidance of a doctor.
