Terrible . I have permanent burn marks from a groupon! But yet IDEAL REPS. State the Estitician s know what they are doing??? so how come I got burnt ? I had to stay out of the sun for 1 year and still have marks on my legs. I'm not longer keeping silent. Just because the company offers me a free facial . That will never be enough to remove the permanent scars on my legs. Thanks for the worst deal of my life.
