Joyce, great question. I'm gonna answer as best I can without any pictures. The key concept here is "harmony". There are certain ratios that work very well (for example, the distance from the upper lip to the bottom of the nose should be the same as the distance from the bottom of the nose to the tip, etc), however, you have to use a combination of these in order to determine what will work with your face in particular. I have had patients who have over projected noses, and therefore a 1:1 ratio does not work, while others who have a very prominent chin, and thus lifting too much with a modified lip lift for volume would make their lower face look too strong. It all depends on what fits well with your face, as the lip lift is a very individual procedure, even though we use it as a great tool to rejuvenate the lower half of the face. I hope some of this helps. Best of luck!
