Hello. I've had 2 subcision appointments, with filler and my acne scar has greatly improved. The scar which was once red has evened out and I've seen great collagen regrowth as well. However, there is a slight part which is more raised the other half of the scar and I'm wondering what would happen if there was simply filler injected, without subcision. Would I be able to see collagen regrowth overtime as the filler dissipates? Or would it just be a temporary lift? Thanks.
