Lighten the skin tone of your anus with the help of bleaching
A bleached butthole will make the holes whiter and smooth in texture.
It matches with the skin tone of your body and makes it look good. But bleaching components are not friendly to the skin and may create some irritation in the butthole. For some skins it might work great, but for the others, it may darken the skin badly. Read the instructions carefully before the application. Many people buy Anal bleach just read half of the instructions or don't read it at all.
Bleaching can surely lighten the color of your anus, but different skin might react differently. Doctors recommendation is needed.
