This is my third time around getting Botox. I have really strong muscles in between my eyebrows and it causes headaches. The last time around I went to get Botox my nurse kept forcing me to get more than I wanted. I'm only 28 and do t want to look frozen. She used 40 units on my forehead, it looked good but I felt frozen and like I couldn't use expressions at all. This time I changed doctors. I went to a place where the doctor actually preforms the Botox and specializes in the face. He only used 20 units! Half the price and a more natural look but still fixed my problem area! Granted my doctor charges more per unit but you pay for what you get. Someone who knows what they're doing and uses less product to give you the results you want...It takes a few days to see your results but will update as soon as I do!
