I actually visited Dr. Serdev a few months ago in Bulgaria. Suture suspension lifts have not been received well historically. Dr. Serdev has built a career with his unique proprietary sutures and instruments. His sutures have an elastic quality to them that move with the tissue and minimize the possibility of them tearing through. Another difference is the use of his specially designed needles that allow for non traumatic anchoring of these sutures to specific areas of the face. I have performed a few of his procedures with excellent results. I do tell my patients that this is not a long term solution as the sutures do dissolve and we have not done any major undermining prior to the lift. Dr. Serdev's results last years and he has the photos to prove it. I still prefer traditional lifting procedures, but only offer it as a last alternative to patients who do not want anything invasive (mostly brows and cheeks) and are aware that this may not last more than a year or two. I also price it accordingly, more like fillers than a procedure.
