How Botox works

Botulinum Toxin Type A, commonly known as Botox, works directly on the nerve system in muscle cells. It causes muscles to relax temporarily and eventually shrink in size.
Because of this, Botox injections are used to reshape the face by reducing the size of overly prominent jaw muscles that cause a wide or square face shape. Many people seek this to regain confidence in their facial appearance.

Benefits of V-shape jaw Botox

  • Facial reshaping without surgery: Since it's an injection procedure, there are no wounds afterward, no need for any recovery time, and it's more affordable compared to surgical procedures. It's easily accessible, and even those up to 15 years old can undergo it.
  • Visible slimming of the face: After V-shape jaw Botox, once the treatment takes full effect, both sides of the jaw muscles will shrink and disappear, resulting in a clearly slimmed and defined face shape. Others will notice the change, which further boosts our confidence.
  • Highly safe procedure: When you choose to have it injected at a standardized clinic, administered by a qualified doctor, using genuine Botox that naturally dissipates without leaving residues, it ensures high safety standards. There are no lingering effects or dangerous side effects.

How many days until results from V-shape jaw Botox?

You can start noticing changes within approximately 2-4 weeks after the injection.

How long does V-shape jaw Botox last?

The effects typically last around 3-4 months before the Botox naturally wears off, depending on individual body and lifestyle habits. After that, you can choose to have another session if desired.

Who is V-shape jaw Botox suitable for?

ฉีดโบลดกราม เหมาะกับใคร?
  • People who have a broad face due to large jaw muscles.
  • Individuals who want to reshape their face without surgery.
  • Those who are not satisfied with their facial shape and desire a slimmer face.
The problem of a broad face isn't only caused by large jaw muscles but can also be due to excess fat on the face or the structure of the jawbone. Addressing these issues may involve other methods such as fat-dissolving injections, Thermage for facial tightening , or surgical procedures.

Is V-shape jaw Botox dangerous?

As I explained earlier, V-shape jaw Botox is a safe injection procedure with very low risks of dangerous side effects. At MEGA CLINIC, we exclusively use authentic Botox products sourced directly from authorized distributors in Thailand.

Preparing before V-shape jaw Botox

Another convenience of Botox injections is that there are no special restrictions in the preparation phase before getting the injection. However, those concerned about persistent needle marks might need to avoid taking supplements or certain medications such as:
  • Refrain from using pain relievers, aspirin, and anti-inflammatory drugs (NSAIDs) for at least 2 weeks before the injection.
  • Avoid taking certain medications, vitamins, and supplements for at least 2 weeks before the injection.
  • Abstain from alcohol for at least 24 hours before the injection.

Post-care after V-shape jaw Botox

The main factors that cause the Botox to dissipate early in the initial period after injection include direct exposure to temperatures exceeding 60 degrees Celsius for an extended period.
For general heat exposure in daily life, such as having hot pot meals, grilling, using a hairdryer, and taking warm baths, these activities can still be performed as usual. However, it is recommended to avoid activities involving high heat exposure, such as:
  • Avoiding laser treatments for a week.
  • Avoiding sauna sessions and steam baths for a week.
After V-shape jaw Botox, you may feel slight fatigue while speaking or chewing food. This is a normal symptom and should improve within 1-2 weeks. As for stiff smiling or incomplete smiling, the chances are very low, but if they occur, they will also resolve on their own.

Q&A: Knowledge about v-shape jaw Botox

Q: I like the results of my v-shape jaw Botox injections. Can I get them often?
A: You can repeat the treatment every 3-4 months, the time it takes for the Botox to wear off.
Many patients notice their jaw muscles don’t return to their original size because the muscles aren't overused during the treatment period.
Tip: Always consult your doctor before deciding. If your jaw muscles are already smaller, you might not need injections as often.
Q: I got v-shape jaw Botox injections, but my face isn’t slimmer. Why?
A: A wide face might be caused by other factors, such as excess fat on the cheeks or under the chin or jawbone structure.
For most patients, excess fat is the main issue. Combining fat-dissolving injections with v-shape jaw Botox can provide better results than Botox alone.

Q: Are there cases where v-shape jaw Botox is not recommended?
A: If your doctor finds no significant jaw muscle enlargement, Botox injections may not be necessary. Injecting Botox unnecessarily can make the face look overly thin or gaunt.
Instead, issues like excess fat or a short chin may need to be addressed. For example,Chin Fillercan enhance the face’s proportions and create a slimmer appearance.

In summary, getting V-shape jaw Botox is a procedure that helps contour the face, making it slimmer. It's suitable for those worried about a broad or square face due to large jaw muscles.
