The girls who have performed the laser treatments on me have been great with explaining the treamtment and supportive during the laser sessions. I had a groupon for my underarms and decided to purchase the extended bikini once I visited the office. I've just completed my 6th treatment for both and believe that the underarms will be taken care of completely if not only one more treatment will be needed. An additional one or two treatments will be needed for my bikini. I was told in advance that touchups may be necessary, unlike some other comments, I wasn't surprise and I'm willing to pay the additional money for the touchups since I purchased the treatment with a groupon. Knowing that I could be hairless is completely worth the discomfort and price! :) Thanks Masri laser techs!
