Has Anyone with Rolling Acne Scars Had 3 or More EMATRIX Procedures Done and Seen Any Results?

I have had 2 sessions of Ematrix and will do the 3rd in 2 weeks. My sessions are spaced 5 1/2 weeks apart. I have seen absolutely NO change. I know collagen takes a minimum of 8 weeks to start to build and it has been 10 weeks. I also did not have the tiny little red to brown scabs that form after Ematrix, mine were white and dissappeared within 2 days. My face was red to pink for about 3 days total then back to normal. I am following the pre/post instructions to the letter.
