  1. How to Reduce Lower-Face Prominence with Seongsu-dong Botox

Hello, everyone! Lately, it seems that many people are worried about their face

line. In particular, some may feel that their face looks larger because of a square jaw,

or feel upset that their impression seems strong. Today, for those who have these

concerns, I’d like to talk about masseter Botox. Shall we look together at how to

choose skincare-related care wisely?

※ Why does a square jaw develop?

A square jaw can occur when the jawbone itself is angular, but in most cases it is

often caused by overdeveloped jaw muscles (masseter muscles). The masseter muscles

are used when chewing food, and they can become more developed due to frequent

gum chewing, a habit of eating hard foods, or clenching the teeth tightly.

※ How does masseter Botox work?

Masseter Botox uses a substance called botulinum toxin to temporarily suppress the

movement of the jaw muscles, which can help improve volume reduction. Botulinum toxin

works by inhibiting the release of the neurotransmitter acetylcholine at nerve

endings, thereby paralyzing muscles. When botulinum toxin is injected into the jaw

muscles, it prevents the jaw muscles from contracting, reducing muscle size and,

as a result, creating a slimmer-looking face line.

※ What are the benefits of masseter Botox?

Simple method for improving face line: Since it is performed by injection rather than

with a scalpel, it places less burden on the body.

Quick visible change: You can check a slimmer-looking face line in a relatively short

time. Minimal disruption to daily life: You can return to daily activities right after

care.

  1. Who Is Seongsu-dong Botox for Lower-Face Prominence Reduction For?

※ Who is masseter Botox suitable for?

Those worried about a square jaw

Those who want to improve their face line with a simple method

Those who want a V-line

Those whose jaw muscles are excessively developed and want improvement

※ When does masseter Botox take effect?

The effect of masseter Botox varies from person to person, but generally you can feel

the jaw muscles gradually shrinking about 2 to 4 weeks after care. It may take about

1 to 2 months for the jaw muscles to fully relax and for the face line to look slimmer.

The effect lasts about 4 to 6 months, and it is recommended to receive it again at

4- to 6-month intervals. If chin filler is performed together, it can be a good

solution. It can improve and help prevent lines caused by repeated jaw use, and it can

also reduce already developed muscles.

※ How long does masseter Botox last?

The duration of masseter Botox can vary depending on an individual's muscle use and

lifestyle habits, but on average it lasts about 4 to 6 months. If you have habits that

use the jaw muscles a lot, the duration may become shorter, and conversely, reducing

jaw muscle use can help extend the duration.

※ What should you be careful about after masseter Botox care?

After masseter Botox care, it is good to pay attention to the following points.

Please refrain from irritating or rubbing the treated area. For about a week, please

avoid alcohol and smoking. For about a week, please avoid saunas, public baths, and

strenuous exercise. To protect the skin, apply moisturizer and sunscreen carefully.

Washing your face and wearing makeup are possible on the same day.

Thank you for reading this long post.
