What is a jawline injection (masseteric injection)?

Why is Slim Jawline Injections popular?

  • Many Asians have a muscle called the Masseter, which makes their jaw look bulky and their face shape square.

What is the procedure?

  • Masseter muscle is identified.

  • A tiny microinjection of the muscle-relaxing medication is strategically injected into each masseter. This literally takes seconds.

  • Over the next few weeks, Masseter muscles weaken. The weakened muscle will shrink leading to a slimmer appearance.

How long does it last?

  • Slimming effect generally lasts 6-9 months.

  • Thereafter, 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.

  • We recommend the Slim Face injection twice a year for best results all year round. After 3-4 sessions, once a year is usually sufficient for most people.

  • Individual variations exists.

What are the possible complications?

Complications are not common. But these are the possible complications:

  • Over-shrinkage of the Masseter muscle can make the cheeks look hollow. This will settle with time.

  • An asymmetrical smile that will settle with time.

  • Paradoxical bulging of the Masseter. You may need additional injection as this is usually due to unusually large Masseter muscles.

What other procedures are available to achieve a V-line face shape?

This depends on what is causing the square-shaped face. There are many causes. It can be due to bulky masseters, chubbiness (fat), loose skin, prominent jaw, or a short chin. There are various methods of producing a beautiful slimmer jawline.

  • Masseter injections can be used to shrink the masseters – as we discussed in this webpage.

  • Fat dissolving injections can be used to dissolve excess fat, or buccal fats can be removed surgically.

  • HIFU – Ultrasound Skin Lifting is used to tighten small amounts of loose skin.

  • Chin enhancement using filler injection or a chin implant

  • Combination therapy is used if the cause is due to a combination of the above.
