Does anyone know what this is?

I’ve had this rash type thing on my right breast for a while but it recently spread to my left, my doctor thinks it is just acne but there’s no way that it’s acne. July 21

This is what it looks like now August 4, my skin isn’t wet but it looks glossy idk why and it’s been peeling. I still don’t think it’s acne.
