I purchased a groupon for multiple microderm abrasions. I have used a number of them at this point. The quality of the treatment varies from staff to staff. One woman seemed to rush and when I commented that the suction didn't feel normal (i.e. not very strong), she told me that it was as high as it could go and it was working fine. Usually, the technicians are thorough and attentive.
Great value salon. I have been to many through various deal sites and this one seems pretty standard.
