Thank you! I should have cut out the CeraVe as soon as I noticed I was breaking out just to make sure but I had heard so many good things about CeraVe that I didn't really think to do it. I find it odd that it's pretty much only the right side of my face reacting though! I don't even speak on the phone that much ughxfactor wrote:^ The CeraVe in a tub and foaming cleanser didn't work for me at all. for the first week or so all was fine but after that it just lead to closed comedones. if i were you i would cut out both of those, replace them with whatever you were using before and see how you get on. theres a chance its hormonal (cheek, jaw, chin acne often is, unfortunately speaking from experience here). other than that, i would change my pillowcase frequently, make sure my cell phone was clean and avoid touching/leaning. i know ive heard (probably on reddit's skincareaddiction sub) of people using the hydrating Cerave with no issues then switching to the foaming and it not agreeing with them at all.
