I just wanted to warn: I love my micro kit by SPA, but, the moisturizer has oil in it, and I started to break out after just one use, and I don't have sensitive skin. SO, I suggest if you use this, to use the crystals but not the serum cream. Of course, I have very oily skin. You can try for yourself, but keep an eye on other kits too. I will still use this and will write SPA and BEG for a oil free formula!
