Botulinum toxin is injected into the large masseter or chewing muscles on the angle of the jaw line to slim down the face. Very often Asians have a square jaw due to subconscious grinding of the teeth at night or excessive chewing which can cause the masseter muscles to become very bulky.  Botulinum toxin will relax the muscle and allow it to shrink in size over time to produce a more slimmed down V shape face.

When will I see results?
Results are usually visible gradually over time in the 1-2 months after the injection.

How long will the results last?
Depending on the cause, results can last up to 6 months and if done regularly less toxin is required to maintain the desired shape.


Botulinum Toxin is injected very superficially into the skin along the jawline to achieve contraction and tightening of the lower face. The dermalift can be combined with dermal fillers to produce a well-defined and V-shape jawline that extends harmoniously all the way to the chin.

How long will the results last?
Results can last up to 3-4 months. Our patients are recommended to come 3 times per year for continued lifting results.

Is it safe?
Yes, it is a safe procedure with no long term side effects. There is no downtime and normal activities can be resumed straight after.
