- Virtually no downtime, treatment time 15-30 minutes.
What are Botox Injections?
Botox is an injectable drug that uses a protein called botulinum toxin, and it acts on muscles to temporarily suppress excessive contraction. It allows control over muscle movement in various areas without surgical procedures. The effect is not permanent and naturally wears off in about 3 to 6 months.
Effects and Features by Area
| Area/Concern | Effect | Duration |
|---|---|---|
| Jawline (Masseter muscle) → Face slimming | Reduces the masseter muscle to slim the facial contour. Effective for prominent jawlines and teeth grinding. | 4-6 months |
| Forehead/Frown lines | Suppresses the movement of facial muscles to make wrinkles less noticeable. | 3-6 months |
| Crow's feet (corner of eyes) | Improves dynamic wrinkles at the corners of the eyes. Reduces wrinkles when smiling. | 3-4 months |
| Corner of mouth/Gummy smile | Lifts the corners of the mouth/improves excessive gum show. | 3-4 months |
| Armpits/Palms (Hyperhidrosis) | Suppresses nerve transmission to sweat glands. Highly effective and fast-acting for hyperhidrosis. | 6-9 months |
💡 Botox for hyperhidrosis is a powerful treatment option alongside Perspirex. If Perspirex is not effective enough, or if you desire a longer-lasting effect (6-9 months), Botox is suitable. For more details, please refer to "What is Perspirex?".

Frequently Asked Questions
It varies depending on the area, but for jawline and dynamic wrinkles, 3-6 months is a guideline, and for hyperhidrosis, 6-9 months. Some people find that with repeated treatments, a smaller amount can maintain the effect.
With the appropriate amount and injection location, your expressions will not be frozen. Excessive amounts can sometimes look unnatural, so our clinic prioritizes natural-looking results when determining the dosage.
