Botulinum is a substance that is produced by a bacteria. It is then refined, purified, diluted and used in therapeutic doses. It is administered by injecting in into a specific facial muscle where it acts as a muscle relaxant.
Botulinum is most effective in improving lines or wrinkles due to facial expression for example, worry lines or frown lines on the forehead and between the eyebrows. This is because these lines are usually caused by overactive muscles and the treatment stops these muscles from contracting and causing the wrinkles.
In most cases the treatment takes between 10 and 20 minutes. Very tiny needles are used and only small amounts are administered. As a result any discomfort is usually minimal and sort lived so there is no need for local anaesthetic.
Some people may experience localised bruising and slight swelling or redness at the site of the injection, however this is generally minimal.
The effects of the treatment will begin to appear within two to three days, however the full extent of the treatment may not be visible for up to two weeks after the procedure.
The initial treatment will last for between three to four months after such time you will begin to see a gradual fading of the effect. At this stage you may return for another treatment. With repeated therapy, the effect lasts longer.
