I've been noticing very mild skin laxity (a fallen brow and deeper creasing around my mouth/dynamic lines/a). I'm 37. I think eventually I would need a face lift since it seems to be the gold standard, and I use Dysport to address the lower brow. However, I'm interested in laser to tighten up my jaw. Could C02 laser tighten skin? I tend to hypertrophic scars so I can't do micro needling.
