I have used the machine a couple of times a week for the past several weeks. It is wonderful. No problem with the suction and actually removed a couple of clogged pores that I had been trying to get my Clarisonic to take care of for months. Gone in one use. I loved that. My face, neck, chest and hands look so much better already. Cannot wait to see what long term results will be. I have always tried to get a salon facial every six months or so but couldn't afford the microdermabrasion so I am thrilled to be able to do this at home. I follow up the treatment with a vitamin C product and rose absolute oil which I love. Skin glows!!
