Hello,

I am Dr. Ki Beom Park, Medical Director of GU Clinic.

One of the most common search terms

associated with body Botox is '100 units.'

​

Many patients ask, 'Is 100 units enough?' or 'Will it really make the area look slimmer?'

The answer depends on what is making the area appear bulky in the first place.

​

Body Botox does not remove fat.

It works by reducing muscle activity,

which may gradually decrease the volume of an overdeveloped muscle.

When prominent muscle development is the main reason an area looks thick,

body Botox may help create a slimmer contour. If fat or swelling is the primary cause,

a different treatment approach may be more appropriate.

​

In other words, the number 100 is less important than

a careful assessment of your individual anatomy and body composition.

"How Does Body Botox Work?"

Body Botox uses botulinum toxin to

temporarily reduce signaling between the nerves and the targeted muscles.

​

Muscles tend to become more developed

when they are used repeatedly.

When nerve stimulation is reduced, muscle activity decreases,

and the muscle may gradually become less prominent over time.

​

This principle can be used for areas such as

the trapezius, calves, upper arms, and thighs

when excess muscle development makes

the body line appear broader or heavier.

​

The degree of change varies according to

each person’s muscle size, anatomy, and daily activity.

"Is 100 Units a Large Dose?"

Many people assume that 100 units is the key factor

that determines the result of body Botox.

In clinical practice, however,

the number alone does not tell the whole story.

​

There is no single dose that is automatically

too little or too much for everyone.

​

A unit is simply one part of treatment planning.

The appropriate amount depends on the size

and strength of the muscles being treated,

as well as the number of areas included in the plan.

​

Even when treating the same area,

one person may be suited to 100 units,

while another may require a different amount

because of differences in muscle volume, exercise habits, and lifestyle.

"Treatment Also Varies by Area"

The purpose and injection plan differ

depending on the body area being treated.

​

• Trapezius: May soften the neck-to-shoulder line

  and reduce the appearance of bulky shoulders.

• Calves: May reduce prominent gastrocnemius muscles

  and create a slimmer lower-leg contour.

• Upper arms: May reduce muscular volume

  for a lighter-looking arm silhouette.

• Thighs: May improve a bulky contour caused by

  excessive muscle development.

​

Even with the same type of body Botox, the dose and injection pattern

should be adjusted to the treatment area and individual muscle anatomy.

"Body Botox with Coretox"

Coretox is a botulinum toxin type A product manufactured with

a purified formulation and designed without complexing proteins.

​

• Its formulation excludes non-toxin proteins and human serum albumin.

• Key feature: A highly purified formulation intended to

  minimize unnecessary protein exposure.

• Who may consider it: Patients who are concerned about

  repeated botulinum toxin treatments and treatment resistance.

​

When selected for an appropriate patient,

it may support a smoother and slimmer body contour.

​

However, the physician should first evaluate muscle volume,

development, left-right balance, and the contour the patient

hopes to achieve before selecting the product and dose.

​

Careful planning is needed to determine how much

should be distributed to each area and how muscle activity can be adjusted

without making movement or the final contour look unnatural.

One advantage of body Botox is that it does not require

the prolonged recovery associated with surgery.

​

The procedure can be completed relatively quickly

and may help create a slimmer upper-body silhouette.

​

During the warmer months,

patients who would like a more refined body line

and a better fit in sleeveless tops or fitted clothing

may consider body Botox after an in-person medical assessment.

​

Thank you.
