I didn't get on with the tri-enzymes either. I do suffer with acne scarring now and then, and was hoping the tri-enzymes would sort it out and make my skin look porcelain perfect or something, however I didn't see much of a difference in my skin!
Also, what I hated about the tri-enzymes range was the fact that it was such a drying regime. My skin lost it's plumpness. You also aren't meant to use any other range alongside whilst using the tri-enzyme regime. . and I hated that, since I like to mix and match my skincare.
Bought the enzyme discovery kit off QVC a few week back, and tried the gel mask. Liked the result, however I believe my Alpha-h glycolic mask gives me far superior results and actually HYDRATES to boot!
