Hi Ive been using differin for about 7 weeks now and my skin has become absolute garbage. I have like 30 pimples on my face and they stick out so much. I think maybe this is caused by me applying too much differin? I find it very difficult to use the recommended pea size amount for my whole face so I end up applying more. I was wondering if mixing he differin with my moisturizer(so I can actually get a pea size amount all over my face) works? Or would the moisturizer affect the effectiveness of the differin?
