ACNE PROBLEMS! HELP

Michelle
Hello Everyone! My entire life I've never had a problem with pimples. However, lately I've been having tons! I have a lot on my chest and back. On the other hand, my face hardly had any besides on my forehead or the side of my face. Any tips or recommended products i can use or do? Please help, i feel really uncomfortable and i have to wear a dress for a presentation and i feel really insecure about my acne. 😞
