Muscle Relaxant

When we perform facial expressions, our muscles contract, causing the skin on our face to crease. Over time, these lines become permanent wrinkles, contributing to an aged appearance. Muscle relaxants are used to treat specific muscles, reducing the appearance of facial lines and wrinkles and creating a more youthful appearance. This procedure is widely used across all demographics to prevent the early signs of ageing.


What Is being injected?

Due to Australian advertising guidelines, we cannot specify brand names. However, muscle relaxants are made up of proteins that work to relax the relevant muscles.

When injected into the desired area, the product temporarily disrupts nerve activity, causing muscle paralysis and restricting movement. Without this continuous muscle movement, the skin can rebuild underlying structures that help prevent ageing and result in a fresh and youthful appearance.

A muscle relaxant treatment can be performed on its own, or combined with other procedures for complete facial rejuvenation, such as:

Most people notice a difference after several days, and the final result visible at two weeks. Results typically last for three to four months, but this can vary from patient to patient. Patients with muscular physiques may require more frequent treatments with more product. Regular treatments will help maintain results, and over time, people may find they can go longer between touch-up appointments.

What to expect

Muscle relaxant is a prescribed medication, and only a qualified medical practitioner can perform the treatment. The product is injected into the target area using a very fine needle. The injections may sting for a few seconds, but most patients describe it as quick and painless. The procedure usually takes 15 to 30 minutes.


All cosmetic treatments involve both positive and negative outcomes, and carry certain medical risks which will impact your well-being. The known risks and complications associated with muscle relaxant are listed below:

  • Transient headache
  • Swelling, bruising, bleeding, pain, twitching, itching, puffiness/oedema around the eyes or numbness or other changes in sensation
  • Asymmetry (unevenness)
  • Temporary drooping of facial features, including eyebrows, cheeks, and mouth – occurs in two percent of cases and could last three weeks
  • Dry eyes
  • Double or blurred vision
  • Allergy including anaphylaxis is possible but very rare
  • Occasionally the treatment wears off very quickly or does not work at all
  • Muscle relaxant is best at treating dynamic facial lines; those caused by facial muscle activity, lines present at rest may or may not improve and can be unpredictable
