I have dark inner thighs, can natural shea butter lighten my thighs?

Medical grade skin brighteners and/or prescription strength hydroquinone will help to lighten the skin on your inner thighs. You can also treat the area with medium grade chemical peels to help speed up the lightening process.
Hope this helps!

Usually laser seems like the top option. actually using a gentle skin peeling such as urea or retinoic acid is a good tool for that treatment
