This is a guide to Botox compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
Botox and filler are often confused because both are relatively simple procedures performed only by injection. However, their operating principles are completely different. We have compared and summarized how the two procedures differ and what situations they are suitable for.
Key Differences at a Glance
| Category | Botox | Filler |
|---|---|---|
| Principle | Relaxes muscles to reduce wrinkles | Fills areas lacking volume |
| Suitable for wrinkles | Dynamic wrinkles caused by facial expressions | Sunken areas and static wrinkles |
| Main areas | Forehead, glabella, crow's feet | Nasolabial folds, cheeks, lips, nose, chin |
How Botox Works
Botox is an injectable made by purifying botulinum toxin. When injected into developed muscles, it reduces the action of neurotransmitters, thereby relaxing muscle movement.
- Changes can generally be observed in a short period.
- Usually, one treatment lasts about 6 months to 1 year.
- The duration of effect may vary by individual.
If you have a habit of frowning frequently, you may receive it as a preventive measure before wrinkles deepen.
Diverse Applications of Botox
It is used not only for wrinkles on the forehead, glabella, and around the eyes but also for improving facial lines.
- Overly developed muscles like square jaw
- Trapezius muscles or calves
- Treatment for hyperhidrosis
However, it is essential to use genuine products and the correct dosage, and to proceed only after thorough consultation about the area. Special caution is required for procedures performed by non-medical professionals.

How Filler Works
Filler, as the name suggests, is a procedure that injects and fills areas with wrinkles or lost volume. It is used to improve the face three-dimensionally.
- Various areas such as glabella, forehead, under eyes, nasolabial folds, cheeks, lips, chin.
- Can be used for localized areas or for overall facial contouring.
- Hyaluronic acid fillers can be dissolved and adjusted if the shape is unnatural.
Conclusion
