TMI Embarrased But I have to ask. (I didn't know what board to post it on)

Hello everyone!
I had RNY in 2008 and TT in 2009.
Still working with some re-gaining issues but I am working hard.
I exercise, I wear shorts. My inner thighs still rub together. Sorry, TMI.
I've noticed that my skin is darker in that area.
Does anyone know how to lighten that area? What to buy or what to make?
Please help. Any advise will be great.

Thank You

maybe skin bleach will work?

When I had this issue, I went on Amazon and did a search for either skin lightening and I searched for skin whitening.  The inner thigh area can be a big concern, but with the proper products, the darker areas will fade quickly.
