The silhouette Facelift is just another "thread lift", instead of separating sagging tissues, lifting them and repositioning them, this procedure relies on barbed sutures placed percutaneously through the skin to keep the tissues up.
Experience has shown repeatedly that this does not work. These sutures dislodge, move, become infected and become visible or palpable (aka positive Banjo strings sign).
EVEN the Spanish based company itself on its website (http://www.silhouette-lift.com/page-questions_reponses-15-UK.htm) states:
"Q: Is Silhouette Lift an alternative to a traditional Facelift?
R: A Silhouette Lift can not replace a traditional face lift if you are considering this procedure. It is, however, an effective way of postponing a traditional Facelift for several years. " As for their meaning of "several years", it states: "Q: How long do the results last? R: As of today, the track record on the Silhouette Sutures is two years for plastic surgery "
People who lose a lot of weight generally have a deflated appearance which requires a comprehensive, individualized face and neck lift. This method is very unlikely to satisfy your needs and is not used by the overwhelming number of members of The American Society of Plastic Surgery.
I would pass if I were you and see another ? real Plastic surgeon.
