You might have seen references to anal bleaching in tv comedies and films, Bridesmaids and The Perfect Couple to name two. It's a thing. Someone who shall remain nameless, watched some porn (consensual, female directed) and wasn't phased by the threesomes.. what shocked her was the bum hole of the lead character when it was front and centre of the action on screen. Which lead her to question if her butthole looked like that.
With anal bleaching, you are lightening the skin, not the hair surrounding the butt hole. Woowoo Lighten it! was designed specifically for this purpose. It gently lightens the skin back to the surrounding skin tone - you won't get a halo... if that's what you want you'll need to go the salon. If you regularly apply to your chocky star it will be less chocky star and more shine bright like a diamond.
It can be used on other areas of pigmentation, although you need to apply sunscreen if the areas are exposed to the sun.
