Acne between my boobs!?

Camellia • Anime Freak!!!! 😜😜😘😘❤❤❤
So in the past year I have been breaking out between my boobs badly, I'm not too concerned but I would like to get rid of it. I constantly wash there hoping it's like acne on my face and just needs special treatment but it hasn't gone away. Any handy tips?
