The CleanZyme & SkinZyme system from Jan Marini is awesome!
I use it at night and have done it 4 nights in a row for a jump start.
I will likely do it about 3x a week from now on.
It is a bit spendy, but actually you don't need much per application.

It is really subtle at first, just makes the skin smooth and glow a bit.
But, after a few days I think it really made a big difference in discoloration and breakouts on my face. I have been using Dan's AHA afterward, either spot treatment or whole face (right before bed). I have also been using a high frequency machine to zap zits (so awesome for cysts).
This combo seems to be working nicely for me.

The AHA and the HF alone were helping my skin.
I have also been using isClinical Active serum regularly (still unsure about this) and I just started using Colorescience Wild to mild under my mineral makeup.
When I added the Jan Marini everything seemed to work better!

I will have to update my "regimen".

FYI - Dan's AHA is so awesome for arms and back too. I don't breakout there (thank goodness), but it really makes the skin smooth and supple - I LOVE it for my arms, and think I may try my legs too!
