After I went for a round of 6 professional microdermabrasion treatments *I had the crystal microdermabrasion used in the spa* I noticed how great my skin was after that soI did LOTS of research to find a salon quality diamond tipped microdermabrasion machine.The reason I chose diamond tipped is for many reasons;1. Cheaper because you do not have to replace crystals like other machines. Also, when I was using the salon my results were inconsistant. About 3 out of 6 provided obvious results. When her chrystal machine was working properly I had great results but when It was not I would leave there with chrystals all cloging my pores. Also I would have the Aluminum oxide crystals in my nose. If I would have been smarter I woulnt have gotton a treatment with chrystals because having them enter your lungs can be dangerous:( Since I loved the good resluts I decided to research how to get a diamond tipped one they give NO debri (all skin sucked up is put threw two filters that should be replaced after each session.2. The diamond tips can be cleaned with a soft *must be a soft* tooth brush, toothpaste or dawn and hot water *Be sure before putting any of your tips near the sink that you have a plug in the sink. You would not want to loose any of these precious tips. Diamond tips are also far better for your health than the *crystal system* because there is not any debri put into the air and since it is diamond tipped there is nothing to clog pores. From my experience with the chrystals I had inconsistant results becuse the machine has to both blast out chrystals and suck the debri up at the same time. The Professional Diamond Microdermabrasion Machine HB-SF01 by Kendal is the absolute highest product on the market. This product is the type that is used in day spas and dermatologist offices. It comes with 9 different diamond tips.3. It is very easy to use and easy to clean.
