Using Botox above the upper lip helps relax the muscles, which prevents the upper lip from curling in while smiling! This is a great way to balance your smile and look a bit poutier while looking natural. Because you move your mouth so much every day (between talking, singing, eating, etc), the Botox wears off a little faster than it typically does in other parts of the face. The Botox lip flip lasts around 1-2 months on average before you have to come back for a touch-up!
