Vulvar psoriasis is mainly treated with topical medication, and phototherapy can be applied when the effect is not good, and systematic oral drug treatment is generally not used. 1. Topical medication: The vulvar skin is relatively thin and tender, and a weak to moderate-acting glucocorticoid ointment, such as hydrocortisone acetate, can be used for topical treatment. Vitamin D3 derivatives such as tacalcitol can also be used, which are less irritating and better tolerated. Alternatively, topical calcineurin inhibitors such as tacrolimus and pimecrolimus may be used. 2. For those who are not well treated with topical medications, narrow-spectrum medium-wave ultraviolet radiation can be used. If you are diagnosed with vulvar psoriasis, it is recommended that you consult a doctor in time, standardize the use of medication under the guidance of the doctor, and take the medication according to the doctor’s instructions.
