1. What is BOTOX Injection and How Does It Work?
BOTOX is an injectable drug that uses a protein called botulinum toxin to temporarily block signals from nerves to muscles and sweat glands. By paralyzing muscles, wrinkles are improved, and by blocking signals to sweat glands, hyperhidrosis is alleviated. The effects are not permanent and naturally wear off in about 3-9 months.
✅ "Unnatural expressions" are a thing of the past. Nowadays, techniques for appropriate dosage and injection sites have been established, allowing for effective results while maintaining natural expressions.

5. Frequently Asked Questions
It varies by area, but generally every 3-6 months for jawline and facial wrinkles, and every 6-9 months for hyperhidrosis. Some people find that with repeated treatments, a smaller amount can maintain the effect.
With the appropriate amount and injection site, your expression will not become stiff. Our clinic prioritizes setting dosages that result in a natural finish.
First, check your usage (night, dry skin, 2-3 times a week). If it's still ineffective even with correct use, BOTOX injections are a valid option. They have a lasting effect of 6-9 months, and one session before summer can cover the entire season.
