Facial Slimming injections
Genetically Asians are predisposed to a wider lower face.
In oriental culture a square face is linked as more masculine & unhappy life.. An oval face is linked with being more obedient and feminine.
Many factors contribute to the square look:
- Widening of the mandible bone
- Thickened chewing ( Masseter Muscle)
This width is frequently referred to as “benign masseteric hypertrophy.”
Masseteric hypertrophy is thought to be due to excessive action, particularly diet factors – chewing dried squid, meat, fibrous vegetables, betel nut, etc. Additionally Personal habits – jaw clenching/grinding of the teeth.
Historically, surgical techniques with resection portions of the bony mandible with and without removal of the masseter muscle, has been performed.
More recently, the use of botulinum A or B toxin (BTX) has been reported for the correction of masseteric hypertrophy. See an Example.
Muscle relaxing injections (BTX) in a single treatment can improve the look.

The procedure requires 5-6 injections in the area of maximum muscle thickness.
Shrinkage can be seen by day 14, but does not reach a maximum until at least week 4, and sometimes not until week 12.
Duration of ‘cosmetically desirable effect’ is variable, but typically 3–12 months.
The injections are virtually painless and are placed in the thickened muscle mass over the jam angle. No disturbance of jaw function has been noticed by patients of the clinic.
The technique of facial slimming can be combined with Meso BTX therapy.
Meso BTX(or Micro BTX) is a procedure where multiple superficial micro doses are injected into the skin of the face and neck, causing sweat glands and sebaceous glands to shrink and atrophy. This results in smooth clear skin without loss of movement in major facial muscles.
