Bulky or square jaws can be due to bone structure, the over-development of masseter (jaw) muscles or a combination of both.

The treatment of square jaws, due to bulky masseter muscles, involves a simple non-invasive and zero downtime jaw reduction injection treatment. Square jaws due to bone structure, on the other hand, usually require invasive jaw reduction surgery which is associated with significant downtime.

Fortunately, for a large group of Asians, bulky jaws are usually caused by a genetic predisposition to bulky masseters. A consultation with Dr Kellyn Shiau in Singapore will help you in determining the cause and she will be able to provide medical advice on your suitability for the jaw reduction treatment.

What is Btx Jaw Reduction Treatment in Singapore?

If you want to achieve a more youthful appearance or the classic V shape face look, one of the most effective non-invasive procedures is btx jaw reduction. At Lux Medical Aesthetic Clinic, we specialise in jaw slimming btx and other face contouring procedures that can help you to reinvigorate your appearance and get the look you are searching for.

Btx for jaw slimming is especially effective for anyone who feels their jawline is too square or too prominent, and would prefer a more contoured and refined V shape face. One of the keys to this is masseter muscle reduction (the muscles in the jaw area that help us to bite and chew), as overly large muscles in this area can lead to a bulky-looking face or a too prominent jaw.

Btx jaw contouring is a minimally invasive, largely pain free process that requires little or no recovery time, which means you can attain your ideal look without the inconvenience of downtime or having to adjust your lifestyle.

What causes a Square or Box Jaw?

A bulky or excessively square jaw can be the result of over-developed masseter muscles, your underlying bone structure, or a combination of the two. It can also be the result of genetics and ethnicity (often the case for Asian people), while some lifestyle factors (e.g., excessive chewing or teeth grinding) can also contribute to enlarged masseter muscles and a box jaw appearance.

Jawline reduction btx can address these issues and create better a proportioned chin and jaw, slimming your face and producing a more sculpted, refined appearance.

What features help to create a V Shape Face?

V shape face will usually be one that is slim and oval-shaped, and which narrows down to a clearly defined jawline and chin. As a result, the face seems thinner and smaller, and overall these features combine to create a healthier, more youthful look that is highly desirable among women of all ages.

Jaw slimming treatment can therefore help to create a V shape face through shaping the jawline so that it appears less bulky and more sculpted.

How does Btx Jaw Reduction work?

Jaw contouring btx treatment is a non-surgical, non-invasive procedure that helps to create a more refined jawline and chin.

The process is quick and relatively straightforward, involving a series of small btx injections in the masseter muscle. Btx effectively relaxes and reduces the size of the muscle, smoothing and softening its appearance and creating a more clearly contoured and desirable shape. Masseter reduction btx treatment also helps to reduce the facial angle and ensures that the jawline and chin are better proportioned.

How is Btx Jaw Reduction performed in Singapore?

If you are considering btx jaw reduction in Singapore, you should first consult with Dr. Kellyn Shiau and the expert team at Lux Medical Aesthetic Clinic. We provide a range of masseter reduction and face contouring procedures designed to help you achieve a more youthful appearance and a vibrant V shape face.

Jaw btx reduction is a non-invasive procedure that requires the administration of btx through a series of small injections in the area being treated (usually between 1 – 3) using super fine needles. Numbing cream may be applied to ensure that the procedure is completely painless.

The entire process is quick and easy, so much so that it can be performed during a lunch break, and there is virtually no downtime required afterwards. Once a treatment session has been completed, you may experience mild needle marks, if any, but this subsides very quickly, usually within a couple of hours.

The muscles take 3-5 days to relax and approximately 4-6 weeks to slim nicely. Masseter reduction btx can also be undertaken in conjunction with other face contouring procedures in order to achieve a total face slimming effect.

How many units of Btx/Dysprt do I need for Jaw Reduction?

The amount of Btx or Dysprt (another brand name for btx) used in a treatment session is measured in units, and so the total BTX jaw reduction cost you pay will to a large extent depend on how much is used, as well as how often you have treatments.

A session of jaw contouring btx will, on average, require around 24 units of Btx or 50 units of Dysprt in each treatment area on both sides of the face. Whether Btx or Dysprt is used may depend on your specific facial features and your ultimate goals.

How long does it take for Jaw Btx to work?

Although there may be some visible effect shortly after a jaw reshaping btx session, the full impact does not begin to be seen until around 3 to 4 weeks later.

How soon can I see results after injecting my Jaw/Masseter Muscle?

While the ultimate outcome of masseter reduction before and after will be a change to your appearance, this is unlikely to be very apparent immediately. While In some cases you may notice some differences more quickly, it will generally be 3 or 4 weeks until the full effect becomes apparent.

How long can Btx Jaw Slimming last? How often should I do Btx Jaw Reduction?

Generally speaking after the receiving the treatment the muscles take 3 to 5 days to relax and the slimming can only be seen after 4 to 6 weeks. The results of btx jaw reduction will last for around 6 months (although it can be shorter or longer, depending on the individual). Therefore, if you want to maintain the full effect, it is recommended that you have regular additional treatments every 4 to 6 months or so.

(NOTE: Depending on the patient, those who tend to clench their teeth more, grind their teeth or generally prefer diets that require more chewing may find that their muscles may grow back faster in comparison to others)

As well as ensuring that you maintain your V shape face, there is also the advantage that over time, less btx is needed in a treatment session to maintain your look. It can also be the case that the results last longer once you have had a number of treatment sessions.

Can Btx Jaw Reduction be combined with other treatments?

However, there are no age or gender barriers in place, so talk to our team if you would like to find out whether you are a suitable candidate for the procedure.

Am I suited for Btx Jaw Slimming/Masseter Btx?

If you have facial muscles that are firm and your skin is still relatively taut and has not begun to sag, then you are likely to be suited to btx for jaw slimming.

How much will Btx for Jaw Reduction cost?

The overall btx for jaw reduction cost you will be required to pay will ultimately depend on the number of units used in each treatment.

At Lux Medical Aesthetic Clinic, we offer a Jaw Reduction Package consisting of 200 units, which starts at $1,650 (plus 7% GST).

Btx has been used for a variety of medical and cosmetic procedures for many years all around the world. Provided it is administered by an experienced practitioner in a properly appointed facility, jawline slimming with btx has consistently been shown to be very safe and have minimal side effects. These can in some cases include swelling and some redness in the treated areas, but these will subside very quickly. Some people may find that immediately after treatment they can experience some discomfort when chewing, but this does not tend to last for long.

Jawline btx is designed to slim the face and add more definition to the jaw and chin area, but it does not lead to the skin in these areas sagging or drooping.

Some people may find it a little uncomfortable or tiring to chew food immediately after having masseter reduction btx, although this is relatively rare. However, the feeling is short-lived and in most cases it has gone within a few days.

Jaw Btx has been shown to be a completely safe treatment for jaw slimming and achieving a V shape face. It is a minimally invasive procedure that is largely painless and does not result in any serious side effects. Any swelling or redness that results is minor and temporary, while any difficulties in chewing as a result of the procedure do not last longer than a few days.

Jaw btx contouring is not a permanent procedure. In most cases, the effects of the treatment will last for around six months (although this can vary from person to person). After this time, if you want to retain the full effect of your jaw btx reduction, additional treatments will be required. The effect of each subsequent treatment may last longer than the previous one (potentially up to 12 months, over time), although the results will not at any stage become permanent.

There is almost no downtime required after masseter muscle reduction btx. The injections are small and carried out with very fine needles, and so the injection points disappear virtually straight away.

Many people choose to have injections for jawline slimming during their lunch break, and are then able to return straight to work the same day with no difficulty or discomfort.

The results of masseter jaw reduction btx look completely natural. The overall effect is achieved gradually and so there is no sudden or dramatic alteration to the shape of your face. The effects are subtle and so do not impact on your smile or other facial reactions.

Some people fear that btx jaw reduction side effects lead to a frozen or plastic looking face, but this is not the case. The effects take place gradually over a period of 3 to 4 weeks, and so your new look emerges over time and appears entirely natural. Your facial muscles will continue to work normally and you retain full mobility, so your expressions will not be hampered or look frozen in any way.

Not everybody’s facial physiognomy is suitable for jaw btx contouring. For instance, the treatment does not change the bone profile of the jaw, and therefore if this is the reason why you have a square or box jaw, jaw btx reduction will have little or no effect.

At your initial consultation with Dr. Kellyn Shiau, it is important to have a clear idea about your goal and the look you are trying to achieve. It can then be determined prior to any treatment if jaw btx reduction is right for you, or whether surgical procedures may be required.
