I had a few rounds of restylane and subcision for an atrophic scar on my face but the area immediately became infected in a zit looking thing and I had to go in 3 times to have the pus drained.It came back less each time. It's been a few months now and the pus seems to be gone but my scar is looking worse than ever and I want it refilled. When (if ever) would be a safe time to proceed and should all the filler be dissolved first?
