So I have really dry skin and after applying the benzoyl peroxide my skin gets really flaky. I have been using the cetaphil cream instead of the moisturizer the regimen comes with. It's been working great! However, I recently started to break out on my cheeks. It's been really hot and I work outside all day in a sweaty environment. I know that my breakouts are from the sun. So my question is should I apply my moisturizer on before using sunscreen or just use the sunscreen as a moisturizer? And what is the best sunscreen to use for acne prone skin?
