Over the past year I have had a total of 7 pixels done. My main concern was acne pitting on my cheeks. The scars are much shallower, possibly 50-70% improved. The overall texture is also much finer, with my pores less noticeable.
This is not an overnight treatment, one time thing. Filling in of scars occurs over months, and with repeated treatments. Everyone heals at a different rate. Therefore, this should not be done by those that expect instant results for scarring. Although texture improvement was seen immediately.
Initial healing takes about 3-5 days for me depending on the level of treatment (they started low). You will look like you walked in to a dirty screen door. That is just the pattern of the pixel laser. While the process is long, I would never go back to the skin I used to have. BTW, you can have treatments more often than I did, I just had to squeeze it in to my very full schedule.
