[Seongsu/Ttukseom] How to Reduce Neck Circumference! Slim Neck Botox Effects

[Seongsu/Ttukseom] How to Reduce Neck Circumference! Slim Neck Botox Effects

Hello! This is Sio Clinic.

​

When you look in the mirror,

you diligently manage facial puffiness or body shape,

but is there a part you've neglected?

​

It's the 'neckline and neck thickness' that drops from the neck to the shoulders.

​

​

Especially when the weather gets warmer and clothing styles become lighter,

or when you have an important schedule and wear clothes that reveal your neck or a neat updo!

​

Many people feel subtle stress due to a thick neckline and a blunt back-of-neck line.

​

​

A delicate collarbone line and a slender, long neckline

make your overall proportions look much slimmer.

​

Conversely, a thick and short-looking neck

can give a stuffy impression,

and can easily make you look bloated.

So, are there effective ways to reduce neck circumference

and regain your hidden feminine

neckline?

Why does my neck look thicker and thicker?

​

Even though you've been dieting diligently and lost weight,

are you concerned that your neck circumference or thickness

just won't decrease?

The reason is the structure of our neck muscles.

The main culprit that makes the neck look thick and short

is the

'sternocleidomastoid muscle (SCM)'

​

What is the sternocleidomastoid muscle?

​

It is a large, long muscle

that extends diagonally from behind the ears on both sides of the neck

to the collarbone.

​

It's the muscle that prominently protrudes

when we tilt or turn our head to the side.

Reasons for SCM muscle development

When you maintain poor posture habitually,

or when chronic tension persists around the neck due to stress,

or if you have a body type where this muscle is naturally well-developed,

it gradually becomes thicker.

​

​

When the SCM muscle thickens, the entire neck looks shorter

and can give a somewhat stern appearance.

​

This is also why it's difficult to reduce the volume of this deep muscle

with regular massage or stretching alone.

​

What is Sio Clinic's Slim Neck Botox?

​

Sio Clinic's Slim Neck Botox in Seongsu/Ttukseom

is a procedure that injects Botox into the SCM muscle,

the cause of a thick and blunt neck, to reduce muscle size.

​

​

By refining the angle and curve from the neck to the collarbone

to be slender and soft,

it provides the effect of making the neck look much longer.

​

You won't just experience a reduction in neck circumference;

you'll feel the entire neckline become slender and smooth.

✔Procedure Time: Approximately 5-10 minutes

✔Anesthesia: Comfortable cream anesthesia

✔Recovery Period: Immediate return to daily life

✔Swelling/Pain: Very minimal

Who is this recommended for?

Those who need to wear updos

Flight attendants, announcers, or those preparing for wedding photoshoots,

or body profile shoots

who are concerned about their back-of-neck line

Those with an unkempt back-of-neck line

who want to tie their hair up but are bothered by

stubborn baby hairs or uneven lines

Those with short, thick necks

Those whose necklines look stuffy due to their natural body type or muscle development

Those who desire a delicate body

Those who want to make the line from their neckline to their shoulders appear more slender

Those whose necks and shoulders often feel stiff

Those who habitually feel stiffness due to poor posture

​

We design the most harmonious neckline

by comprehensively considering each patient's body type, neck length,

and muscle development.

​

​

We use only genuine products with proven safety,

approved by the FDA and KFA,

and adhere to the principle of using the correct dosage.

Synergy Procedures to Consider

✔Salivary Gland Botox

Reduces the size of overdeveloped salivary glands

below the ears or under the chin,

creating a defined jawline and a clean

border between the face and neck.

​

​

✔Trapezius Botox

When combined with Slim Neck Botox, softening the

raised shoulder trapezius muscles

creates a fantastic line where the neck appears longer

and the shoulders drop straight.

Post-Slim Neck Botox Precautions

✔Do not lie down for 4 hours after the procedure

To prevent the medication from spreading to surrounding muscles,

it is recommended to remain sitting or standing for about 4 hours.

​

✔Avoid massage and pressure

For about 2 weeks after the procedure, avoid

rubbing or massaging the treated area vigorously.

​

​

✔Refrain from alcohol and smoking

For optimal recovery, it is recommended

to avoid alcohol and smoking for 1 week

after the procedure.

​

✔Avoid high-temperature environments

Immediately after the procedure, avoid very hot places

like saunas or jjimjilbangs, or extremely cold places.

​

✔Avoid lifting heavy objects

For about 2-3 days after the procedure, it is safe to

refrain from lifting heavy objects or engaging in strenuous exercise.

​

​

If you've been concerned about your neck thickness and blunt neckline

in the Seongsu and Ttukseom station areas,

don't stress alone any longer.
