Great question. Thread lifts have come and gone at some point during the last 15 years. There is always improvements made to the material and incremental gains in what can be achieved with them. However, they are limited in what they can achieve and for how long. That being said, as others have noted, this will not decrease the possibility of having a tuck up lift at some point later on - however, you should wait 6 months to a year before embarking on this as you want the tissue to settle. Even if old threads are encountered during lifting, you can take care of them during the surgery. You don't lose anything by starting the consultation process now. It would give your surgeon a chance to examine your tissue and get an idea of where the threads were placed such as to know what to expect. Best of luck!
