Is propyl tin pill copper useful for vulva white shift?

Hello, leukoplakia vulvae "refers to the thickening of epidermis, depigmentation of basal layer of epidermis and reduction of superficial dermal blood vessels caused by lesions, so long-term treatment should be adhered to." "Drug therapy can take vitamins. If the vulva pruritus is serious and affects sleep, some sedatives can be taken appropriately, and 1% hydrocortisone and 1 ~ 2% testosterone ointment can be applied locally. This treatment can last for 6 ~ 8 weeks, 3 ~ 4 times a day. While insisting on long-term treatment, keep the vulva clean and dry for a long time, don't wear too tight underwear, don't wear chemical fiber underwear with poor permeability, and eat less allergic food.
