How long does a lip lift take?
Durations need a definition
Any lip lift duration you find should come with a statement of what it counts.
What the number might be counting
When a page says a lip lift takes a set amount of time, quote it and ask which clock it uses. It could mean only the surgery, or it could include preparation, anesthesia, and time in the recovery area. The numbers are not comparable until you know which one is meant. A hospital system's page on the lip lift procedure and a plastic surgery society's article on lip lifts and other lip augmentation procedures are both worth reading with that question in mind. A journal paper, such as one on integrating orthognathic surgery into lip lift for subnasal aesthetics, is a different kind of source from a medical society page, so note which kind you are reading. That paper is about a lip lift combined with jaw surgery, so any time it gives belongs to that combined plan.
Two times to get in writing
Ask your surgeon for the time of the operation itself and the time you should plan to be at the facility, and ask for both in writing. The same society's comparison of lip enhancement treatments is useful if you are still deciding between a lip lift and something else, so check whether each option comes with its own time claim.
Your plan sets the timing
Your surgeon's plan for your face sets your timing, not a general page. This is not medical advice.
