At HBIO Clinic, we are committed to helping you achieve a slimmer jawline with safe, non-surgical solutions. In this guide, you’ll explore the most effective types of botox for jaw slimming and get detailed instructions on how to mix botox for jaw slimming following clinical standards.
What Is Jaw Slimming Botox?
Jaw slimming botox, also known as masseter botox, is a cosmetic procedure where Botulinum Toxin A is injected into the masseter muscles. This treatment weakens the muscles, making the jawline appear more contoured and V-shaped. It is ideal for individuals with enlarged jaws due to muscle hypertrophy rather than bone structure. The effects usually last between 6 to 9 months.

Most Popular Types of Botox for Jaw Slimming
Not all botox brands are created equal. To ensure safety and optimal results, it is essential to understand the differences between reputable products and unregulated alternatives. Below are the most widely used types of botox for jaw slimming categorized by origin and quality.
High-Quality, FDA-Approved Botox Brands:
-
Allergan (USA):
A global leader in aesthetic medicine, Allergan is FDA-approved with visible results in 3–5 days. It causes minimal swelling or bruising and lasts up to 9 months. Though it’s more expensive, the safety and consistency make it a top choice. -
Botulax (South Korea):
A favorite in the Asian market, Botulax delivers fast, visible effects. It’s exclusively available at certified clinics and is best suited for clients who prioritize premium quality. -
Neuronox (South Korea):

Unverified or Unregulated Botox
In addition to high-end products, many facilities use botox of unknown origin to reduce costs. However, the risks are extremely high.
Floating, pre-mixed botox without certification from the Ministry of Health often does not guarantee the ingredients, easily causing complications such as swelling, facial distortion or severe allergic reactions.
How to choose the right type of Botox for jaw reduction
- Prioritize products with clear origins and licenses from the Ministry of Health.
- Do not use float botox, premixed botox or botox that is no longer in its original packaging.
- Inject only at reputable cosmetic facilities, by doctors with a practice certificate.
