I did Ultra Encore Pulse 3 times and Erbium Yag Fraxel 3 times. I had a lot of rolling boxcar scars on my right cheek. Once you get Ultra Encore Pulse, the redness lasts a long time. It's very red for about two months and it gradually disappears. But it hasn't completely gone away since it's been two months. I'm going to wait for now. There is definitely an effect on scars. Even if I received a lot of non-dermabrasion treatments, there was no effect at all, but that's not the case here.
