Just logged in to say that I also had a terrible experience with laser treatment, specifically Fraxel Repair. I had it done on both entire sides of my face and it made almost no difference to the scars but gave my skin a very dry, orange-peel texture that turns red easily and doesn't deal well with sunlight. It's been about 5 years since then but it's improved a ton since that first year, I think applying rosehip oil everyday religiously made a big difference. One round of subcision however with no fillers made a massive difference to my scarring, even though many doctors like to claim it's "outdated" because laser is so much easier and marketable. If you have sensitive skin I recommend you stay far away from lasers, the only scarring I think it could improve is very shallow superficial scarring.
