Please help is this yeast on my skin?

I’m guessing it would be from sweating outside but it’s miserable and I was wondering if there’s any way I can make it go away fast. Anything I could buy, to make it less miserable.

This is what happens with big boobs in the heat and I hate it. I’ve had it before but never this bad. This is killing me.

Idk , I shower everyday and wash underneath my boobs and then lift them up and hair dry with a fan so this DOESNT happen but whatever.
