Im pale white. i was treating psoriasis flare up near genital area and now it is even whiter than my normal skin. (i was scratching and sometimes misused steroidal creams). is this discoloration permanent?

It may be permanent if you were regularly applying prescription strength corticosteroid ointments or huge amounts of nonprescription ones. I trust the diagnosis of genital psoriasis is accurate and that you don't have lichen sclerosus which is an intensely itchy condition of the vulva and can cause whiteness. .Make sure of your diagnosis by a dermatologist and,either way, get up to date treatment
