I got discoloration on my inner thighs after I had my baby what is this from and how do I get rid of it?

Try using a skin lightening cream containing glycolic acid, kojic acid or hydrquinone on the effected area twice a day for 1-2 months. These ingredients are good for fading dark spots and discolorations. You will find skin lightening creams at your local drugstore or pharmacy in the skin care section.
