3x picosure focus + ematrix for acne scarring?

I am asian and i am just treating 1 atrophic scarring , it is quite huge. Done 3 picosure focus, there was some raise and improvement. I am not sure i can afford another 4th picosure so i am eyeing for ematrix now. Will this be ok? Will adding 1 ematrix tx give me result since i already have done 3 pico?
