Lip Flip
A lip flip uses a very small amount of a neuromodulator, such as botulinum toxin, around the upper lip to temporarily relax targeted muscle activity. This allows the upper lip to roll slightly outward, making more of the lip visible without actually adding volume.
Procedure Intelligence is for learning only. It does not decide whether a procedure is right for you—a qualified clinician should review your goals, history, skin, and medications. Important Information
What it can do
Create a subtle outward roll of the upper lip and, in some cases, reduce the appearance of a gummy smile.
What it doesn’t do
It does not add volume like lip filler. Someone wanting actual lip volume or a larger change in lip shape may be looking for a different treatment.
What to expect
A lip flip generally uses a very small amount of neuromodulator and is a very quick procedure. A common technique uses approximately four small injection points around the upper lip, although the exact number and placement vary by anatomy, product, clinician, and treatment goal.
The mention of a common number of injection points is descriptive education only—not an instruction or recommended technique.
How long it lasts
The effect is temporary and may wear off sooner than neuromodulator treatment in some other areas of the face. The muscles around the mouth are used constantly for talking, eating, drinking, facial expression, and other lip movements, which may contribute to a shorter perceived duration for some patients.
Important to know
Cosmetic use of botulinum toxin for a lip flip is off-label. “Off-label” does not mean prohibited; it means the specific use is not an FDA-approved indication for the product. A qualified clinician determines whether it is appropriate for an individual patient.
Because the muscles around the mouth are functionally important, unwanted effects can include temporary difficulty with activities involving lip control, such as drinking from a straw, certain speech movements, whistling, or keeping liquids contained. These effects, when they occur, are usually temporary.
