Drooping upper lip: From Aging, Rhinoplasty or related to jaw/bite problems? (photos)

There are surgical and non-surgical approaches to lip augmentation. Non-surgical approaches include botox (slight lift, reducing gum show) and filler (volume restoration). Surgically, you can have two separate incisions under the nose (italian), one incision under the nose (bull horn), one incision at the red/white upper lip junction (gull wing) or two separate incision at the corners, or a combination, depending on your desired look and anatomy. My preferred surgical technique is called the Elelyft, which is a version of the bullhorn approach.
The ideal candidate for the Elelyft, or upper lip lift, is someone with a philtral length of 15mm or longer, no upper dental show, and/or a thin upper lip. The nasal base to mouth width ratio needs to be taken into consideration to avoid leaving the lip corners down.
In your situation, it cannot be determined what exactly is causing the philtrum to increase in length. A filler could increase the size of the lip, but a lift is a more permanent solution. Consult a medical professional to explore all options.

You would get a nice improvement with lip fillers. Volbella, Restylane, and Juvederm are good to create a symmetrical lip. NovaThreads can be used to improve lift and shape. Implants or fat are alternatives. Technique will be important here, so you'll want to see someone meticulous. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer
