What happens post 18 months InstaLift?

Thank you for your question.  InstaLift doesn't simply wear off.  The sutures do resorb and are replaced by collagen.  The longevity of the results are more a function of how quickly your aging process shows visible signs that mirror your pre-procedure state.  If you like the results, you should talk to your physician about other maintenance activities such as peels, microchannelling, injectables, skin care, etc... that work in tandem to enhance your results and works synergistically to reduce the signs of aging.

The Silhouette Instalift is a remarkable procedure for lifting lax skin and stimulating your collagen.  The threads and attached cones dissolve during a two year time frame.  The face continues to age with loss of the underlying supportive structures.  The threads and collagen support the face during this time which slows process.  

This is an excellent question.

The Instalift is an excellent procedure to re-contour the face, lifting deeper layers of the skin for a more youthful appearance.  You see immediate results and there is no downtime.
Over time the sutures are naturally absorbed by your body while stimulating production of collagen to aid healthy renewal of your skin to produce natural-looking long lasting results.
