Mechanical dermabrasion by a surgeon

I could really use some advice here. I have a surgical appointment scheduled in about three weeks for mechanical dermabrasion at a General Motors clinic over at the Coca-Cola facility. I’m dealing with some acne scarring—nothing massive or super deep, but they definitely bother me. BUT... I’ve been falling down a rabbit hole online the last few days reading about this stuff, and honestly, I'm getting a little spooked by some of the potential side effects people mention. I guess I'm just wondering if anyone here has actually gone through with mechanical dermabrasion or has any experience with the Coca-Cola clinic specifically? Or maybe you've tried something else with a surgeon or a dermatologist for acne scars? I’m not looking for input from estheticians; I've had some pretty bad experiences there in the past. Help please!

So, I went through the whole fractional laser thing twice now—paid full price for both sessions, by the way$1000—and honestly? I’m beyond disappointed.
I mean, look, my skin probably has more damage than yours, but I'm pretty sure nothing could actually be worse than what this damn laser did to me.

Good luck with your plan.
