Help for depressed acne scars? (photos)

Hello, I have some deep acne scaring on my cheeks. One long scar on one side and a few smaller ones on the other side. My dermatologist injected them with restylane. It looked great for a short time, but it only lasted just over a month. Other than $500 injections every month (can't afford that forever) is there anything I can do? Please help. Thank you!
