Dark skin removal???

Mitzi
Hey ladies! So I have a question, so Im really insecure about my lady parts. I was noticing that in between my butt cheeks it's really dark, almost black. Im a Hispanic but I'm a very light Hispanic (often confused for a white girl) I've heard that sweat stains skins and such but I was wondering if anyone knew of a way to whiten that area? My inner thighs are also getting dark. Please help!
