Hi, ever since I was around 10, I started to get this brown dirt on my breasts and nipples. As I got older, I showered better. Now I'm 18 and yet I still sometimes get brown crusts or dirt on my areola and very light brown crusts on my breasts.My nipples are also peeling. I shower everyday, I don't understand why. The brown dirt on my breasts and nipples would go away whenever I thoroughly scrub but they always come back weeks later. If it helps, I also have some of it on my torso near my ribs. But the one on the ribs aren't brown, they're more black-ish so it could be dirt. Could it be a skin problem or a breast problem?
