Suggest Remedies For Discoloration Of Skin Around Vagina

Hi, i have bad discoloration on my vagina area. I am an african american and my vagina is 10 times darker than my skin tone. It's been this way for years now perhaps from shaving i've tried everything and am now wondering if it is even possible to look in to the area of chemical peels? Is this just a facial treatment or varies? and lastly, are there any other options you may be able to suggest?
