Would I benefit better from a lip lift or lip fillers? (photos)

Your lip shape, symmetry, and volume are all very very youthful and beautiful. Your lip position relative to your upper and lower jaw impossible to evaluate because all photos show upper lip and lower lip coapted, together, closed, cannot see where teeth are. You might however benefit from levator advancement of your upper eyelids if you want a more awake look. Your MRD1 (marginal reflex distance) is below normal. If you are happy with your eyes, do nothing, no surgery at all. You can simulate the result of an upper lip lift yourself in the mirror with cotton tip applicators, gently lifting the central upper lip, and deciding if this creates an enhanced appearance you want. Best wishes, ENJOY your youth and beauty!!!

Based on your pictures, you would benefit from a 3D lip lift as your philtrum is long. The 3D lip lift incorporates the technology of the OOS lip lift and results in better results and less scarring than a regular lip lift. In addition to the 3D lip lift, I would also recommend a Medialized External Corner Lip Lift to roll out the vermillion of your upper lip.

I hope this helps
Best of luck !
