Can Botox Lift the Upper Lip?

Before considering having neurotoxins like Botox or Dysport injected to lift or "flip" the upper lip, it's important to understand what exactly these products do. Botox and Dysport are injectable medications that temporarily prevent the muscle that's being treated from contracting. When it is injected into the orbicularis oris muscle above the lip, it limits movement in the area. This can result in an unnatural smile and appearance when talking, as well as restricted movements such as drinking out of a straw or even eating. 
An alternative to flipping the lip is to have dermal filler injected from above the upper lip. Doing this will look natural and you can still have regular movement when talking, eating, or smiling.

Okay so the corner of your upper lip turns inward. This is an unfortunate part of aging; something that is essential to correct in order to maintain youth. The best way to correct this is by fillers. Botox into the LOWER lip/chin will not help your upper lip. The only way to stop the effect of the orbiculares, which allows you to close your lips, is to Botox it. I can't stress how delicate this procedure is. The muscle must be paralyzed such that it prevents the inward turning but continues to allow you to close your lips.
There are few physicians that do this with Botox. I frankly don't have the nerve to try this as the potential complications, inability to close the lips for several months, is too great. So before you go to your dermatologist see a plastic surgeon for real possibilities of correction without the potential devastating complications.
