I'm interested in getting a lip lift to minimize the distance of my philtrum? I already have fuller lips (Photos)

An upper lip lift does three things:
1. Shortens the distance of the base of the nose to the upper lip Vermilion.
2. Allows your upper teeth to be seen, which is aesthetically beneficial in most cases.
3. Everts the upper lip Vermilion (rolls it outwards) to a very minor degree. I tell my patients that if they are coming to me for an upper lip lift and expect a a good deal of added "real estate" to their upper lip, they will be disappointed. An upper lip lift will give you an alluring, model-type look as you see in the glossy fashion magazines. To get a complete assessment, a plastic surgeon needs to see you in person and also assess your upper lip against the backdrop of your upper teeth when your mouth is slightly parted.

You have excellent symmetry shape and defintion of the upper lip. A upper lip lift will overly shorten  the distance of the lip from the base of the nose to the vermillion of the upper lip and tend to increase the fullness of the upper lip and you would  no be happy with the result. 

The pictures show your upper lip clear. May be it's a little too long but the most important factor is the amount of upper tooth show. Lip lift is done to improve that proportion of upper lip and tooth show so photos with mouth slightly open is ideal. If you would like more  information specific to you, a consult via skype or phone can be helpful. Best wishes
