So I've had acne problems for awhile now, but the acne on my chest is somewhat different from face acne. I used to pop pimples I had on my chest right in the middle of where the pecs meet and after it healed, the skin that showed up was very weird. The skin colour of the middle of my chest is pinkish due to having pimples there which makes it stand out even more.

Usually where the pimple was, it would form little small and soft bumps under the skin that didn't hurt, but could still be slightly seen. It shows up even more if I squeeze the skin area around the middle part of my chest slightly together, the bumps tend to wrinkle slightly showing that the skin is not tight around that area.

Does this go away on it's own sooner or later? Can I do anything to help it heal?
