This machine is GREAT. My pores are so much better. Wrinkles are softer. Skin's general appearance much improved. I was using twice a week, then every 3 days. I slowed to once a week after several months and might hold there for a month or two to see if this frequency will hold me. I had purchased the machine under a different name a the suction would give out after 2-3 months of regular use. DD's machine has lasted the longest, very strong suction. Including the Hydroshield and Daily Defense cream made this an increadible value.
