Botulinum toxin

Botulinum toxin A is a neurotoxic protein produced by the bacterium Clostridium botulinum. Botox is a brand name and other products are available for injection for aesthetic use.

It works by blocking signals from the nerves to the muscles. The injected muscle can no longer contract, which causes dynamic wrinkles to relax and soften. It is most often used on forehead lines, crow’s feet (lines around the eye) and frown lines. Wrinkles caused by sun damage and gravity will not respond to this treatment. Treatment is reversible as the effects of the product wear off after a few months.

Botulinum toxin A has other medical applications apart from cosmetic use. The most relevant and effective is for the treatment of axillary hyperhidrosis (excessive sweating). Results can last between 4-12 months.

The effects of this treatment are not immediate and they can take up to 2 weeks to develop, although you’re likely to start to notice some effects after 48h. It is therefore important to have a follow up consultation 2 weeks later top assess if any corrections are necessary.

Treatment with Botulinum toxin needs to be performed by a practitioner who is familiar with the anatomy and function of the facial muscles and soft tissues. Placement of the toxin needs to be precise to avoid complications (eyelid drooping or ptosis, asymmetry, etc). It is important to assess each patient individually to achieve best natural results.
