do you know where it’s

actually injected?

Q. Jawline Botox = masseter Botox

isn’t it?

A. They’re different.

The masseter reduces volume beside the jaw,

and jawline Botox is a treatment that suppresses the

platysma, which runs along the boundary between the neck and jaw.

Q. Then what is the platysma?

A. It’s the thin muscle that pulls upward from the neck

and under the jaw when you clench your teeth and go “ugh~.”

If it becomes developed,

the jawline looks blurry and saggy.

💡 Dr. Woo Young-jin’s

key insight

It is platysma Botox, which places Botox in the superficial layer of the skin

along the jawline.

It removes the neck muscle that rises when we go “ugh~.”

Have you tried going “ugh~”?

That’s the platysma

Try it now.

In front of a mirror, gently clench your teeth

and make an “ugh~” sound,

and you’ll see the muscle rising from the neck under the jaw

stand out clearly like cords.

That’s the platysma.

This muscle starts from the neck

and attaches in the superficial layer under the skin along the jawline.

It’s not very visible normally,

but when it becomes developed or skin elasticity decreases,

it can make the jawline look blurry and spread out,

or appear pulled downward.

This is a common misunderstanding,

but if you search for “jawline Botox,”

you’ll find a lot of masseter Botox information.

The masseter is the thick chewing muscle behind the cheek,

in front of the ear,

and what actually makes the jawline look sharper

is more directly controlling this platysma.

These two differ in location, purpose, and injection depth.

The masseter must be injected deeply,

while the platysma should be injected into a very superficial layer of the skin.

The tricky part is that

even a slight mismatch in injection depth

can change the effect.

The key is to inject accurately into the superficial layer.

👨‍⚕️ Dr. Woo Young-jin’s key summary:

The core of jawline Botox is the platysma,

that is, suppressing the thin muscle that rises from the neck

when you go “ugh~.”

That’s because this muscle pulls the jawline downward

and makes the line look blurry.

Since it is a treatment placed densely along the jawline

in the superficial layer of the skin, the injection position and

dosage settings determine the result.

For whom

is it actually effective?

To be honest, platysma Botox

is not equally effective for everyone.

These are the people who see the best results.

First, people whose neck muscles stand out clearly like cords

when they go “ugh~.”

If platysma development is confirmed,

this treatment works very directly.

Second, people whose jawline is sharp but

appears to sag downward or look blurred and broken up.

Cases where muscle tension is the cause rather than

decreased skin elasticity fall into this category.

Third, people whose jawline has seemed to collapse

over the past 1–2 years without weight change.

In such cases, platysma sagging is often the cause

rather than fat.

But there is one important point here.

If the fat layer under the chin is thick,

or the skin itself is severely sagging,

platysma Botox alone has limitations.

In these cases, it’s appropriate to combine it with fat-dissolving treatments

or lifting procedures.

It varies by case,

but I usually determine the direction during consultation after

seeing the “ugh~” movement directly.

Among people who had jawline Botox several times elsewhere

and didn’t feel the effect,

there were often cases where only masseter Botox

had been repeated.

The approach was different.

Quite a few patients were satisfied after

2–3 sessions once the platysma was accurately targeted.

Frequently Asked Questions

Q1. Platysma Botox,

won’t it make facial expressions look awkward?

A. The platysma is not a muscle

that plays a major role in facial expressions.

Since it isn’t mainly used when smiling or speaking,

when injected at an appropriate dose,

there is almost no awkwardness in everyday expressions.

However, during the first 1–2 weeks after the procedure,

there may be a slight pulling sensation in the area.

If too much is injected or the position is off,

the neck movement may feel unnatural,

so dosage control is also important.

Q2. How long does the effect last?

A. Generally, about 3–6 months.

The platysma is a thin, broad muscle,

so depending on individual muscle mass and lifestyle patterns,

there is some variation.

With repeated treatments,

the muscle gradually becomes thinner

and the maintenance period often gets longer.

Q3. Can it be done together with masseter Botox?

A. Yes, they can be combined.

If masseter Botox reduces the volume behind the cheek,

platysma Botox

helps refine the jawline itself,

so the target muscles of the two treatments are completely different.

When done together,

they often work complementarily,

so many people plan them together.
