Help! Very dry skin and acne after switching to oil- based products!

J

I was so excited to switch to oil- based products. At first they worked so so so well. I was so pleased. And then, I got this TERRIBLE hormonal breakout on my jawline! Also, I can't for the life of me get my jawline to stay hydrated. It's itchy and flakey. Ever since that bad breakout, I've been using cerave's products. Any advise?
