Horrible chest acne!

This is super embarrassing but 4 months ago I had a baby and my skin broke out almost immediately on my face and then on my chest. This is what it looks like now. I have ALOT of scaring ( the dark spots) and the rest is pure black heads and pus filled pimples. At first it was super painful. I couldn’t even hold my baby very well without being in pain or them popping. I’m embarrassed at how I look. I shower, I exfoliate, I use cerave rough and bumpy body wash and I think it’s helped but I need something more effective? Any recommendations?! (I went to my doctor already twice and he said to ride it out since my body and hormones are adjusting again and that due to covid a dermatologist won’t see me at the moment unless it’s urgent.😭😫) HELP.
