Botox works by blocking the transmission of nerves near the muscles, reducing muscle contraction and relaxing them. It is a highly purified protein used to diminish wrinkles, create a V-shaped face, slim calves, and enhance facial contours. Botox is a purified protein derived from bacterial secretions and is particularly effective in reducing dynamic wrinkles.

The form of botulinum toxin type A commonly used in cosmetic procedures has been approved by the U.S. Food and Drug Administration (FDA) and the Hong Kong Department of Health for 30 years. It is the mildest toxin among the botulinum toxins. The typical dosage for a single injection is between 100-200 units. This dosage allows the body to metabolize the botulinum toxin within 4-6 months after injection, so it does not remain in the body. Therefore, Botox is a very safe cosmetic treatment.

After the injection, small needle marks and redness may appear, but they usually disappear within a few hours. In rare cases, some individuals may experience bruising, which gradually fades over a few days and can be covered with makeup.

There may be slight pain at the injection site, but it varies among individuals and depends on the location and size of the muscles being treated.

Generally, the treatment only takes 10-20 minutes, depending on the treatment area and muscle size.

The body gradually metabolizes botulinum toxin, and the effects typically last between 4 to 8 months. After the effects wear off, the muscles will return to their original state. Botox does not create dependency, so you can decide whether or not to receive regular injections based on your own judgment.
