Review (4/5): Works Well
I brought this two years ago and I use it every two weeks. My skin is sensitive so I never turn the power on all the way, about half way strength will do for me. I substitute every other week for regular scrubs (b/c my skin is sensitive and to save $$$) It helps get rid of the dark spot left behind by acne faster than regular peeling gel or scrubs. It cost me about $20/month for the refills.
I use to go to facial places to get it done, cost about $50 each time... wooo!! So I really like the crystalift for its cost, convenient, and effectiveness.
