I also bought what I thought was a great deal on Groupon for 20 Units of botox. I went at the end of August. I have also received botox before and have always had about 20 U in my forehead usually placed uniformly with excellent results. However, this was given mostly on my right side and in a very small amount. I asked how many units she had given me and she said 12 to 14. I felt very ripped off. To top it off, my results were not good and it looked like she had not used any! I had to go to my usual person thereafter. I tried to call a couple of times without any return phone calls. I live on the other side of town and work so I cannot come in easily. The hours this doctor were there were very limited, like 3 or 4 hours a couple of days a week. My experience there was terrible. I will also be writing to Groupon and asking for my money back. Don't waste your money here.
