Picosure focus or ematrix for combined acne scar?

I only have 1 scar id like to improve. The scar for me is in bad shape(atrophic, borders are iregular and slightly raised and pigmented,surrounding skin is rough). Derm told me to have pico, i had 3. Results are: slight raising of the indented scar,edges are softer but raised border is still there and pigmented. My question is, can i instead do e matrix now? Ive read ematrix can adress many types of scarring. Pico has done very minimal results in my case, i also want the raised scar to flatten!
