Good day,
I have had CO2RE resurfacing exactly 2 weeks ago from today for acne scarring and I have a mixture of boxcar, icepick and (rolling?) some odd sunken scars. I would rate my scarring as medium-mild. So far, I have seen modest improvement at best, some scars have soften up and a huge scar on the side of my face that has been bothering me became more level, which is a comfort. There are raised scars on my nose, but a single ice pick, not much to no improvement in those.
I am thinking that it is perhaps optimistically about 5% improvement so far on the cheeks, but about ~1% on the nose. I might be planning to get another procedure done 2-3 months post procedure, though, seeing that it has also improved my skin texture. (it isn't as dead as it used to look)
Take care.
