For patients with psoriasis on the face, if there is no rash on other parts of the body, and there are only a few rashes on the face, the treatment is mainly for external use. You can choose to use ointment containing hormone, such as Eloson, Pervison and other ointment to smear the affected part, or you can choose sulfur ointment; If the local rash is thick, you can choose salicylic acid lactic acid ointment with peeling effect to smear the affected area, or you can choose to use retinoic acid ointment; If the lesions of the patient's rash are relatively limited, it is better to choose topical drugs as far as possible. If there are more rashes on the trunk and limbs than on the face, you can also choose to take oral medicine. The commonly used oral medicine is acitretin, or you can choose to use immunosuppressants, such as methotrexate, cyclosporine, etc., or you can also choose to use traditional Chinese medicine to treat them.
