How Long Does Face Slimming Botox Last?

A face with a broad forehead, pointed chin, and narrow jawline has taken aback all of us. We call it the V-shaped or heart-shaped face that is now considered the most attractive face in the world.

What started off as a trend after Korean drama is now stated as a beauty statement which will stay forever. Celebrities like Shay Mitchell, Manny Jacinto, etc., have a V shape face that always grabs attention.

Some people naturally have either a round or square-shaped face, but sometimes as you age, the skin gets saggy, and the muscle gravitates downwards. The facial muscles lose their tone due to water retention and decreased collagen production. This reverses the “triangle of youth” and makes your cheeks look flat with an ill-defined jaw.

A contoured face with a sleek jawline and a well-defined chin is a beauty staple, especially in Asian countries. With increasing popularity, multiple treatment options have been introduced, including radiofrequency therapies and face lifting. Out of all, the most popular one is Botox face slimming.

Botox in Singapore is a non-surgical procedure with absolutely no use of harmful radiations or threads that may complicate the treatment. It is generally considered safe, and many stars like Sofia Vergara talk about it openly as she says, “If getting a treatment like botox done makes you happier and more confident, then why not go for it? But I also think you have to do your research, so you know what to expect…”

What Is Botox?

Botox is the layman term used for the procedure, which uses the Botulinum toxin type A for multiple medical treatments. It is derived from the bacteria, Clostridium botulinum and is identified as a neurotoxin because of its ability to block the nerve impulses that cause the release of chemicals. As the release of acetylcholine has been blocked, the muscles cannot contract anymore and go into a persistent relaxed state.

Botox injections are not only used in cosmetic procedures but are also employed in certain medical conditions like an overactive bladder, migraine, excessive sweating, and lazy eye.

Botox Face Slimming In Singapore

Botox in Singapore plays a key role in providing people with their desirable face shape. It takes down years of age from the face by removing wrinkles and preventing fine lines. Other than that, it is widely used for face contouring and jaw reduction.

Botox face slimming refers to the use of Botox injections into the facial muscles, specifically the jaw muscle; masseter. The masseter is responsible for chewing and gives the jawline its square or wide shape. Botox is injected into the muscle, reducing its activity hence the bulk. As the muscle is toned down and its size shrinks, it gives your face a petite and more feminine v-line contour.

Another treatment is “masseter reduction”, recommended in people who are habitual of teeth grinding, a condition known as Bruxism. This condition leads to the hypertrophy of the muscle, which then gives the jaw a bigger and bulkier look. Teeth grinding is further associated with symptoms like headache, jaw ache, insomnia, and dental problems.

Before a person opts for Botox, many questions may arise in their mind, for which the below-mentioned answers will prove to be helpful.

What Is The Procedure Like For Botox Face Slimming?

Botox can be injected anywhere on the face, but for contouring and slimming, the lower face is usually targeted. Before the procedure, the physician analyzes the muscle bulk and marks the area which has to be treated.

The skin is then cleansed and numbing cream or an icing block is applied to make the area numb. Using a fine needle, Botox is injected into the marked area over the masseter muscle on both sides of the jaw.

How Many Units Of Botox Do You Need?

The units of Botox injection typically depend on the muscle mass of the individual and the area it is being applied into. The amount also depends on the type of injection used as there are three options available for Botox in Singapore, including Dysport, Xeomin, and Botox.

It is estimated that around 40 to 60 units are to be injected into the jaw muscle for effective results.

When Do You See Results?

The results of Botox face slimming are starts setting in around a week from the day of your injection. However, you might have to wait for up to 2 weeks for the final results to settle and for any swelling or redness to subside.

How Long Does It Take To Recover?

You may experience some redness, swelling, and bruising over the injection site, but this goes away in less than a week. Botox treatment has minimal downtime to no downtime, and you may continue with regular work immediately after the procedure.

Who Is Suitable For Botox?

Only a certified doctor can decide whether you can have the treatment or not after assessing the masseter muscle. The physician checks your muscle’s thickness by palpating it and considers Botox treatment for you if your masseter muscle is hard and large.

However, Botox is not suitable for people whose square jawline is mainly due to their jaw bone. This is so because the treatment has no effect on the anatomical structures.

What Is The Cost Of Botox In Singapore?

The foremost important thing is to know if the procedure would suit your budget. The price of Botox in Singapore is around $500 to $700 for treating both sides of the jaw.

How Long Do Botox Last?

Whenever a person chooses a treatment, they wish for it to last the longest, so they stay hassle-free for a longer period.

The results of Botox face slimming last for more than 4 to 6 months, but as its effects wear off, you may start noticing that your face takes its previous shape. However, with multiple Botox treatments, the muscle loses its shape and maintains a relaxed state which might end up giving you a narrow jawline for a much longer time.

The results of Botox are not permanent, and ultimately the habit of teeth grinding also returns. The muscle which has slimmed goes back to its previous original shape, and the muscle mass increases again, requiring repeat treatments every 6 months.

The Aftercare

There are certain things to do and avoid after the procedure to maximize the effects of the results and make sure that they last long

  1. Avoid taking any blood thinner or anti-viral unless suggested
  2. Do not massage your face, as the toxin may go into unwanted muscles
  3. Avoid drinking alcohol for three days
  4. Avoid harsh exercises
  5. Do not chew very hard for the first few hours

What Does Research Say About Botox Face Slimming?

With advancements and incorporations in the medical field, new treatment methods have been introduced, of which a famous one is Botox.

An experiment was conducted where ten women with masseter hypertrophy were treated with Botulinum toxin A. They all showed improvement and proved the efficacy of Botox for treating Bruxism.

Another study concluded using Botox for face contouring after extensive research and claimed it to be a procedure with minimal recovery time.

Lastly, research showed how within 5 minutes, Botox could shape the lower face by reducing the size of the parotid gland without affecting the production of saliva and give a slimmer face.
