Which muscle was this Botox applied to? (Photo)

The muscle into which Botox (Botulinum toxin) was applied is likely the levator labii superioris alaeque nasi (LLSAN) muscle. This muscle is commonly targeted for aesthetic procedures, such as treating gummy smiles, by injecting botulinum toxin A into it to reduce the elevation of the upper lip and thus decrease gingival exposure.

If there was no improvement in the shape of the lip as desired, it might be due to several factors:

Incorrect Dosage or Technique: The amount of botulinum toxin A used or the technique of injection could affect the outcome.
Muscle Selection: While the LLSAN is a common target, other muscles might need to be addressed depending on the specific aesthetic goal.
Individual Response: Patients can have varying responses to botulinum toxin, and some may not achieve the desired results.
Consulting another doctor could provide additional insights into whether a different muscle should be targeted or if adjustments in technique or dosage are needed.

Hi, I would have treated the Obicularis Oris muscle for a lip flip. I have had really great results with this technique. Other option is to have a little filler but into the lips for a longer lasting facial balancing.

I'm sorry your Botox treatment was ineffective. I encourage you to discuss your concerns with your injector to determine where the injection was made. Another option to correct lip asymmetry for you to consider is fillers. There are some that are designed for the area and will give a natural enhancement.
