Neuromodulations (anti-wrinkle injections)

Expression lines, worry lines, crow's feet and smile lines – whatever you call them, wrinkles can be an unsightly by-product of aging skin. Anti-wrinkle injections, also known as neuromodulation, are a popular way to reduce the appearance of expression wrinkles, to counteract overactive facial muscles producing excessive facial shadowing. Neuromodulation treatment utilises botulinum (products such as Botox or Dysport), a natural, purified protein that when injected into the skin reduces the appearance of wrinkles, facial lines and furrows by relaxing the muscles that can cause them, to create a rejuvenated appearance. This active ingredient, a neuromodulator, is derived from bacteria in much the same way that penicillin is derived from mould.

Neuromodulation can also help with other complaints like exaggerated neck bands, excessive sweating (hyperhidrosis), jaw clenching, teeth grinding and tension headaches.

 

How does the treatment work?

Neuromodulation treatment is a non-surgical procedure whereby a small amount of botulinum is administered into selected facial muscles by a trained medical professional using a very fine needle. The nerve impulse that stimulates muscle contraction is blocked and this relaxes the specific targeted facial muscles that cause dynamic wrinkles (these are the wrinkles that are formed during facial expression). Once the muscles are relaxed, you cannot contract them and continue to make an undesirable facial expression. As a result, the unwanted lines gradually smooth. Excessive muscle action from jaw clenching, teeth grinding and leading to tension headaches can also be controlled by this treatment.

Neuromodulation injections can also be used to block the nerve impulses that lead to release of sweat from the sweat glands (particularly in the under arm area) and reduce the unwanted effects of excessive sweating or hyperhidrosis.
