Facial moisturizer?

So, I have to use this stuff twice a day as prescribed by my doctor.
It's been making my skin dry and flaky, especially around my nose and cheeks. It has reduced my acne though, which is awesome. I need a good mouisturizer. Would I have to get one for dry skin for this? What would you recommend? I'm trying not to spend over like $10. I currently use this but it hasn't been enough recently.
What would you recommend? Thanks!
