Masseter Botox targets the masseter (chewing muscle) at the side of the jaw, while trapezius Botox targets the trapezius muscle running from the neck to the shoulder. Both procedures reduce the volume of an overdeveloped muscle to refine the face line or body line, but the treatment areas and the points checked at a consultation differ. This article is organized around the procedure items at Repic Clinic in Gangnam, located at 318 Gangnam-daero, Gangnam-gu, Seoul, basement level 1 and 2nd floor.

Comparison of Botox Procedures by Treatment Area
| Procedure | Target area | Purpose |
|---|---|---|
| Masseter Botox | Masseter (chewing muscle) | Reduce muscle volume, slimmer face line |
| Trapezius Botox | Trapezius | Reduce the size of an overdeveloped muscle, slimmer body line |
| Calf Botox | Calf muscles | Reduce the size of an overdeveloped muscle, slimmer body line |
| Wrinkle Botox | Forehead, between the brows, around the eyes | Soften expression lines, relax muscle tension |
| Skin Botox | Superficial skin layer | Pore reduction, fine lines, oil control, improved skin texture |
Every item in the table is a Botox-family procedure. The difference lies in which tissue is injected. Masseter, trapezius and calf Botox are procedures that reduce muscle size, while wrinkle Botox relaxes the tension of expression muscles. Skin Botox is a procedure that places botulinum toxin in the superficial skin layer to address skin texture. (Source: Repic Clinic in Gangnam service information)
Consultation Criteria for Masseter Botox and Trapezius Botox
Masseter Botox applies when the masseter is large and the lower part of the face looks angular. It first requires confirming whether the jaw contour is caused by muscle, and the purpose of the procedure is to reduce masseter volume to create a slimmer face line.
At Repic Clinic in Gangnam, trapezius Botox is classified as a body Botox item. Unlike the face, the treatment range is decided by looking at the whole shoulder and neck line. Calf Botox is included in the same category, so the direction of the consultation differs depending on which part of the body you are concerned about.
Precautions to Check Before the Procedure and Order When Combining
After a Botox procedure, temporary reactions such as swelling, bruising or discomfort may appear depending on the area. Tell your doctor in advance at the consultation about any medication you take, any conditions you have and your history of previous procedures.
If you are considering Botox and filler together, the order matters. According to guidance from Repic Clinic in Gangnam, applying both at the same time to the same area can affect how the filler is distributed, so generally it is easier to predict the result by doing Botox first and adding filler 7 to 14 days later. If time is short, doing both on the same day is also possible, and the order and interval are designed differently for each area.
Frequently Asked Questions
What is the difference between masseter Botox and trapezius Botox?
Masseter Botox reduces the volume of the masseter (chewing muscle) to refine the face line, while trapezius Botox aims for a slimmer body line by reducing the size of the trapezius. The injection areas and purposes differ, so what is checked at the consultation differs too.
Can I have Botox and filler together?
Same-day treatment is also possible. Botox relaxes muscle and filler replenishes volume, so how they work does not overlap. However, for the same area, the usual order is Botox first and then filler 7 to 14 days later, and the final order and interval are decided at the consultation according to the area.
What should I check before a Botox procedure?
Effects and course may differ from person to person, so please be guided through a plan suited to your own condition at a consultation.
