So far all I have used is 1 part of the bundle. Very nice. An interesting feel. Really amazing in a mask. The smell is a. More medical smell to me, but the longer you have it on the skin the more it seems to work. After about 5-6 minutes added water and it actually became creamy and so the tiny particles in the substance were able to exfoliate quite well with a little tingle. I do like that. After removing the skin was so soft and was not dried out at all.So I will investigate the next step! Stay tuned.
