Hello,

This is the official blog of Forena Clinic,

which pursues premium skincare

and healthy beauty. 😊

Recently, the procedure many people are seeking

for a slimmer and softer facial line

is “square jaw Botox.”

It is consistently popular among those

who are concerned that their face looks wide

because of developed jaw muscles,

or who want a slimmer facial contour.

Today, we will easily organize

the key information many people are curious about

square jaw Botox in a Q&A format.

Q1. My face looks wide because of my square jaw.

Does your face look wide because of a square jaw,

or do you become concerned about your angular jawline

every time you take a photo?

If you frequently chew food

or repeatedly clench your teeth,

your jaw muscles may become more developed,

making your face look larger from the front

and making your jawline appear more pronounced.

When you notice these changes,

the treatment to consider is

“square jaw Botox.”

Q2. What is square jaw Botox?

What is “square jaw Botox”?

It is a procedure in which botulinum toxin is injected into the muscles used for facial expression,

blocking the release of the neurotransmitter acetylcholine

to temporarily paralyze and relax the muscles.

The toxin is injected into the masseter muscles,

which are used when moving the jaw,

reducing the movement of excessively developed muscles.

As a result,

the size of the developed jaw muscles gradually decreases,

helping to soften angular facial lines

and create a slimmer-looking jawline.

Q3. What types of square jaw Botox are available?

Square jaw Botox products are broadly divided into

locally manufactured and imported products.

It is important to select the appropriate product

according to your skin type, treatment area,

and desired results.

Xeomin / Allergan / Dysport

Xeomin (Germany)

A purified toxin with complexing proteins removed,

suitable for sensitive skin or repeated treatments.

Allergan (United States)

An FDA-approved product meeting global standards,

with relatively strong stability and duration.

Dysport (United Kingdom)

It has relatively good spread or diffusion,

so it is expected to act naturally over wider areas.

Q5. When do the effects appear?

How long do they last?

The effects of wrinkle Botox

usually begin to be noticeable after 2–4 weeks,

with the most satisfying changes seen at 4–8 weeks.

The duration

may vary depending on individual skin condition

and care methods,

but it usually lasts around 3–6 months.

It may also vary depending on

how much the muscles are used.

※ Since the effects and duration may vary depending on individual circumstances, please confirm the details through an in-person consultation and accurate diagnosis.

Q6. Wrinkle Botox

is recommended for the following people.

People who grind their teeth or clench their jaw

People concerned about facial asymmetry caused by their jaw muscles

the results ultimately differ depending on
