I was very nervous after reading about the pain others described but was not willing to medicate with an offered opiate. Took 800 mg of ibuprofen 45 min ahead. I had full face and neck at the highest setting and only asked for one break towards the end when I felt strong pressure like someone was pushing down on my cheek bone. 5 min of sitting up and drinking water and I was able to finish. I actually laughed and chatted throughout the 1 hr 20 min procedure while squeezing a small handheld "vibrator" unit they gave me. The other staff in the clinic all commented on "all the laughter they heard" when we came out of the treatment room!
I am 55, thin with healthy skin, but noticed "jowls and sagging neck" I wanted a natural look and wouldn't consider plastic surgery. Right after the procedure I felt like my skin was firmer. 2 weeks later it just keeps getting better.
I did have minimal bruising above one eye, bottom of the cheeks and under the neck, but I was the only one who noticed it. My face was tender to the touch when washing it or putting on lotion, but otherwise no pain or discomfort.
