I have rolling acne scars. I have read that local subcision with Bellafill can help and that two to three treatments are necessary. I've read it can take up to 3 months to see results, and I've read results can be immediate. 1. When should you see results from Bellafill? If you don't see some improvement immediately, is that a bad sign? 2. How many treatments does it typically make to make a drastic difference? 3. Are there any treatments that work better for rolling scars?
