The treatments were mostly fine, just a sensation of warmth with several unpleasantly hot zaps, but there were never any burns, welts, bruises or swelling. Just a little tenderness for a day or two. During the treatments, gel was applied to the skin which was then zapped in sections. The skin had to be heated to (and remain at) 40 degrees C in order to stimulate collagen synthesis.
3 months after the last treatment, I'd had very little lifting/tightening. I went back to the clinic for the final follow-up and complained of my lack of results. The practitioner was surprised, they'd had good results with other patients - she said. The manager kindly offered me 3 further complimentary treatments. Coincidentally, the Endymed machine had been moved to another clinic so I saw a different practitioner. I could tell immediately that her technique was better. Nevertheless, the results were still unsatisfactory for the amount of time and money invested. All in all, I noticed a 20% improvement to the jowl area, whilst the undereyes and eyebrows seemed to respond slightly better, perhaps a 40-50% improvement. This was a very approximate evaluation - I never saw any of the before or after photos at the clinic and just relied on my own observation. Certainly the results were not enough for anyone to notice.
If the treatment had been considerably cheaper this might not have been such a disappointing result, but for the price I paid it just wasn't worth it. Interestingly, Sk:n Clinics don't seem to be offering the treatment any more, so perhaps they felt it didn't live up to expectations either.
I've just had Ultherapy instead, having been advised that ultrasound skin tightening can be effective on those who do not respond to radiofrequency. Updates on that to follow.
