Slim Jawline Injection

"The best way to stay looking youthful is to streamline your jawline" - UK Daily


What is a jawline injection (masseteric injection)?

  • Asians often have a very strong jaw muscle called Masseter. This muscle bulks the lower face and makes one's face appear bigger and wider.
  • Muscle relaxing injections can shrink this muscle and this produce slim jawline and in turn, make the face appear smaller. 
  • This is commonly referred to as Slim jawline injection.

What is the procedure?

  • Bulky Masseter muscle is measured.
  • A tiny microinjection of the muscle relaxing medication is given to each masseter. This literally takes few seconds.
  • Masseter then weakens and the weakened muscle over the next few weeks will shrink and hence a slimmer appearance.

How does Slim Jaw Injection work?

  • It is a non-surgical technique to create the slimmer face and the desired V line.
  • Many Asians have bulky jaw muscle called Masseter. It makes your jaw look bulky and face shape squarish
  • A beautiful jaw-line can be defined as a slimmer face, long and slender jawline.
  • In females, a feminine curve is more desirable rather than a squarish face.
  • A well-defined jaw-line separates the face and neck and frames the lower face contour, giving the face a slimmer look.

How long does it last?

  • Usually up to 6-9 months.
  • Your masseter muscle strength and the bulkiness will gradually return.
  • Some people need the second injection at 6 weeks depending on the size and the strength of the muscle.
  • Usually, twice a year will give best results all year around. After 3-4 sessions, once a year is usually sufficient for most people.

How can we improve the jawline?
Asians tend to have a wider lower face compared to their upper face. This produces a facial shape that is rather squarish and appears ‘fat’. This distorts a beautiful jawline. There are numerous causes. It can be due to strong muscle, chubbiness (fat), loose skin or a short chin. There are various methods of producing a beautiful slimmer jawline.

  • Muscle relaxing/Slimming Injections are used to shrink strong masseter muscles - "Slim Jaw Injection" - it is the most popular cosmetic injection in younger Asians.
  • Fat dissolving injections are used to dissolve excess fat
  • HIFU Ultrasound Skin Lifting is used to tighten small amounts of loose skin
  • Chin enhancement using filler injection or chin implant.
  • Combination Therapy is used if the cause is due to a combination of the above
