@mjg713I have covered this several times 😉 There is no regeneration, once you have scar tissue minus cutting it out or some discussion in the scarless healing wish list of future dreams. Scar work we soften the scars, make them look better, and blend them with the existing skin. If it's a young scar or surgical scar you put silicone pads over the scar and it sometimes can fill in. Occlusion with Vaseline can also help in a fresh scar, but silicone is better.See a derm if your concerned about the skin. Once the skin has pitted and is a older scar, it's gone and must be volumized - filler/sub and we stimulate collagen, microneedling - etc.
