I decided to give the world of topical treatments another shot and am currently on Retin-A and Sulfacetamide. I've been using the treatment for a little over a week and my skin has become very dry and very oily. Being as oily as it is, I'm a bit concerned that this is going to be clogging pores. Should I use a stronger moisturizer like olive oil, or should i cut these prescriptions out of my regimen for good?
