These are the lines caused by dermal atrophy and repetitive contraction of underlying facial musculature. Unfortunately, these lines can sometimes make you look older than you are. Injection of small quantities of botulinum toxin into specific overactive muscles causes localised muscle relaxation that smooths the overlying skin and reduces wrinkles.

Botulinum toxin injection for treatment of facial wrinkles is one of the most frequently performed cosmetic procedures. These injections particularly in the upper one-third of the face, offer predictable results, have few adverse effects, and are associated with high patient satisfaction.

Patients with dynamic wrinkles demonstrate the most dramatic improvements from botulinum toxin injection and are ideal candidates for treatment.

This may give the face a more harmonious youthful look.

Patients are advised to avoid lying supine following treatment for four hours. They are also advised to avoid massaging or applying heat to the treatment area, and to avoid strenuous exercise heavily, consuming alcohol, and hot tub use on the day of treatment.

The clinical effects of Botulinum toxin injections are seen 1-4 days after injection. Maximal reduction tends to be visible two weeks after injection. Return of muscle function is gradual, typically three to four months after treatment.
