Lip lift, how many mm to take off? (Photo)

The amount of skin removed varies as it is customized for each patient. The distance between the nose and the top of the vermilion border of the upper lip is measured prior to the surgery and, for women, I tend to remove the amount greater than 1.2 cm - though that is an average and there is never one right answer for any two patients.
For the amount of skin excised, be conservative! It is better for the surgeon to err on the side of  ’not taking quite enough (skin)’, than on the side of 'taking too much’. It is very easy to come back and take a bit extra, but you certainly can’t ever replace the skin that has been taken out.
Be sure to consult with a board certified plastic surgeon to determine what is right for you.
Best wishes!

There is a mathematical ratio used when determining how much distance to shorten between the lip and the nose in a subnasal lip lift. As a general rule, the filtrate length should be shortened more than 25% to 33%. This is an irreversible procedure. While you can always do more, you can't every put any skin back.
