Dark Spots on Inner Thighs

Hey there ladies!

I have thicker thighs, so they tend to rub together on the inside and leave dark spots. Sometimes I can't help it like when I go swimming or I'm walking around the house with no pants on. I started wearing boxers under dresses to prevent friction, so that helps. I also tried washing with a scrub and that also helps a little bit.

Deodorant between my thighs tends to make the discoloration worse.

I still have the dark spots though. Any beauty tips on how else to get rid of them?
