Advice on pimples

So I just need some advice on pimples and blackheads between your boobs

I shower day and night I use body scubs use sensitive soaps I take really good care of my skin but I get pimples and blackheads between my breasts I do have big boobs I've changed my soaps and body wash but seems too not go away I was thinking about using pimple cream?

Do you have any ideas?
