Facelift 43 Years Old?

There are different types of facelifts available, and the best procedure for a patient really depends on their needs. Photos would help to provide you with the best advice. At 43 years of age, and based on the description you provided, you appear to be a candidate for a less invasive facelift. A procedure like this will not typically last the length of time you mentioned. I would recommend speaking with your surgeon about this further prior to having any surgery, and seek another opinion if necessary. 

Operating times will vary, and really depend on your individual circumstances, but a facelift with upper and lower eyelid surgery does not generally last 8.5 hours. This is especially the case with a younger patient who does not appear to have many issues. Time in surgery can vary depending on:

1) Complexity of your particular case
2) Amount of work that is necessary to reach the pre-established goals of the surgeon and patient

Did your surgeon give you a rundown of what would be performed during surgery that would cause it to last that long? If you are not comfortable with the information you received, I would recommend seeking a second opinion. I hope this helps and good luck!
