Acne help!!

Jess
On two separate occasions now my body has broken out in acne 😩 my face has cleared up almost completely for the past 6 months, but now I keep getting these weird pimples; in abundance,  all over my body. I have over 20 on my butt, hips, and chest. I don't understand why! 😰 does anybody have any ideas?! 
Thanks so much!!Â
