This is a guide to Botox compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (a 3-minute walk from Konkuk Univ. Station Exit 1).
Botox has become so popular that it is often received without careful consideration. However, it is important to receive even simple procedures safely. In this article, we have compiled checkpoints from the basic concepts of Botox to the effects and precautions of square jaw Botox.
What is Botox?
Botox is a medicine whose main ingredient is botulinum toxin.
It was initially used to treat musculoskeletal spasms, but its use expanded to the cosmetic field after its effectiveness in improving fine wrinkles was confirmed.
- It works by temporarily reducing muscle movement.
- It is widely used for everything from wrinkle improvement to muscle reduction.
- It is also used to treat hyperhidrosis.
Dynamic Wrinkles and Static Wrinkles
The effects vary depending on the type of wrinkle.
| Category | Dynamic Wrinkles | Static Wrinkles |
|---|---|---|
| Characteristics | Clear when making expressions | Indented even when still |
| Botox Response | Expected | Difficult to achieve significant effects |
Dynamic wrinkles around the eyes, glabella, and forehead can be expected to be alleviated with Botox, but deep static wrinkles are difficult to smooth out even if the muscles are reduced.
How Square Jaw Botox Works
Square jaw Botox falls under muscle reduction.
- It is used when the masseter muscles, which are used for chewing food, are well-developed.
- It is also called "petite" because a simple injection can lead to changes in the jawline.
- The same principle applies to other muscles such as the trapezius and calves.

Things to Check Before the Procedure
Before proceeding, please check the following:
- Confirm that genuine products and the correct dosage are used.
- Consider your face shape, fat distribution, muscle mass, and skin type.
- Consult with medical staff who have sufficient clinical experience.
Precautions After the Procedure
It is recommended to follow the following after the procedure:
- Slight bruising, swelling, and stiffness are temporary and will subside within a few days.
- Do not lie down for about 3 hours.
- Avoid massage and excessive pressure.
- Avoid hard foods, and refrain from alcohol, smoking, and saunas.
When Do the Effects Appear?
The effects appear gradually.
- You usually start to feel changes around one month.
- Changes become clearer after two months or more.
- It is usually performed every 4 to 6 months, and there are individual differences.
