Don't just believe what you hear about submandibular gland Botox for double chin

After going out to see the cherry blossoms and getting photographed —

I've been getting a lot more inquiries lately.

One of the most common ones is:

"My chin looks really saggy" —
and when people search at that moment,

what always comes up is Submandibular Gland Botoxthis.

The thing is, a lot of the information out there is actually wrong.
So today, let's set the record straight.

Let me cover three key questions first.

Q. Will submandibular gland Botox get rid of my double chin?
A. No. The results depend entirely on what's causing your double chin.

I'll explain in detail below.

Q. Is submandibular gland Botox different from regular Botox?
A. Yes, they're different. The injection site, purpose, and dosage are all different.

I'll break that down below too.

Q. Can Xeomin be used for submandibular gland Botox?
A. Yes, it's possible. But there's something more important than the product choice.

I'll explain that as well.

Let's first get clear on exactly what submandibular gland Botox is.

Submandibular gland Botox is, as the name suggests, a procedure that injects Botox into the submandibular gland (the salivary gland under the jaw).

The submandibular glands sit on either side beneath the jaw.

When they enlarge, the jawline looks less defined — and from the side, the lower face looks thicker.

This is where many people get it wrong:

Submandibular gland Botox does not reduce fat.

It uses Botox to atrophy the gland tissue itself, reducing its volume.

So whether it works depends on the cause —

is your double chin from fat, or from an enlarged gland?

Getting the injection without knowing the cause means spending money and seeing no results.

I always bring this up before any treatment.

The right approach depends on what's causing your double chin.

There are three main causes of a double chin.

1. Subcutaneous fat accumulation
2. Enlarged submandibular gland (salivary gland)
3. Skin laxity or muscle relaxation

These can appear on their own or in combination.

Honestly, it's something I can only assess after examining you in person — by feeling and pressing the area.

I just can't tell someone "I'll give you submandibular gland Botox" based on photos alone.

Dr. Wi Young-jin's Clinical Notes:
In my experience, among patients who come in for double chin consultations,

Less than half are cases where submandibular gland enlargement is actually the main cause.

Most are due to fat or sagging —

yet they come in having searched specifically for submandibular gland Botox.

That's not necessarily a bad thing.

You can always reassess in person and adjust the approach from there.

One thing I must mention: injection site selection is critical for submandibular gland Botox.

Major blood vessels and nerves run nearby. Without a thorough understanding of anatomy, the risk of complications is real.

What's different about submandibular gland Botox with Xeomin?

Xeomin is one of the botulinum toxin products available in Korea.

Unlike conventional Botox (onabotulinumtoxinA), a pure toxin with no complexing proteinsit is.

To put it simply,

with no complexing proteins, the theoretical risk of developing neutralizing antibodies is lower.

In other words, for those who've been getting Botox for years and feel like "it's not working as well anymore" —
Xeomin can be a viable alternative.

But here's what really matters.

Far more important than product choice for submandibular gland Botox is injection placement and dosage design.

Even the best product won't deliver results if it's injected in the wrong spot.

At Beautystone Clinic, we choose from several products including Xeomin —

selecting based on each patient's condition and treatment history.

Key Takeaway:Submandibular gland Botox is effective only when gland enlargement is the cause. If fat or sagging is the issue, a different approach is needed.

When does it work, and how long does it last?

In my experience, submandibular gland Botox starts to show gradual changes around 2–4 weeks post-treatment.

It's less about a dramatic change in face shape —

and more about a cleaner jawline and a more defined side profile.

In my experience, results typically last around 4–6 months .

It tends to wear off a bit sooner than masseter (jaw muscle) Botox.

That's one downside,

though repeated treatments do tend to extend the duration.

Clinical reports suggest that after 3–4 or more sessions, salivary gland reduction becomes more sustained.

The downside is cost ^^..

It's pricier than masseter Botox, and with a shorter duration, costs add up over time.

Still, for those wanting a defined jawline without surgery, it's a realistic option worth considering.

FAQ

Q1. Will saliva decrease after submandibular gland Botox?

A. You may temporarily notice reduced saliva production. However, the body has multiple salivary glands —

the submandibular gland alone doesn't control all saliva flow, so daily life is rarely affected. Most people adjust within a few weeks.

Q2. Can I get submandibular gland Botox and masseter Botox at the same time?

A. Yes, absolutely. Many patients combine both to slim and refine the entire lower face.

Since the injection points and dosages are calculated separately, it's important to see an experienced physician.

Q3. Can I get a consultation near Hongdae or Seoul?

A. Yes! Beautystone Clinic is located near Hapjeong Station and is open on Sundays.
