Welcome to MedAesthetics

Perth’s Award-winning Boutique Cosmetic Clinics.
At MedAesthetics we offer the entire spectrum of cosmetic and anti-ageing treatments including cosmetic injectables, dermatological lasers and fat reduction treatments.

Facial Slimming Injections (and Jawline Slimming Injections) utilise a common cosmetic medical treatment; Anti-wrinkle Injections (Wrinkle Relaxers). This involves the use of a natural, purified protein that relaxes facial muscles.

Over the past year, we have successfully performed countless facial slimming treatments with excellent clinical outcomes and patient feedback.

What Is Facial Slimming?

Facial or Jawline slimming using Anti-Wrinkle Injections is gaining popularity due to it’s efficacy. At MedAesthetics in Perth, we perform this treatment regularly.

A prominent and bulky-looking jawline is the hallmark of masculinity, but some females opt for this treatment in order to get a rounder and slimmer face.

Masseter reduction treatment (aka facial/ jawline slimming) works by weakening the strength of the Jawline Muscle (The chewing muscle called the Masseter muscle) which results in the reduction of its size and bulk.

MedAesthetics have been performing this treatment for more than 14 years. We have a number of well-trained cosmetic injectors with a special interest in this popular treatment who have performed it many times.

Treatment Information

The process starts with a careful clinical evaluation of the patient’s facial anatomy. The contraction strength and the bulk of the muscle are assessed.

10 – 30 units of anti-wrinkle injections may be needed per side for this treatment to be effective.

Patients are asked to give their feedback 4 weeks after the treatment. Sometimes, a top-up treatment is needed if the initial treatment did not deliver the desired results.

What Are Anti-Wrinkle Injections Made Of?

Purified protein (Amino Acids). We use the leading brands.

Patient Suitability

The treatment suits both men and women with masseter muscle hypertrophy and want a slimmer-looking face and jawline.

The Pain Factor

The clinical team at MedAesthetics is highly experienced and strives to minimise any discomfort associated with treatments. Their fine motor skills and gentle touch are vital assets in ensuring a positive patient experience.

To accommodate the specific needs of each procedure, a range of options may be utilised to reduce discomfort, including the application of high-strength topical numbing cream, inhalation (laughing) gas, local anaesthesia, and the use of skin cooling devices.

At MedAesthetics, we prioritise the comfort and well-being of our patients and are committed to providing a safe and tolerable experience during all procedures.

Not every patient with a bulky jawline is suitable to have this treatment. Sometimes, it’s the facial fat, jawbone itself, or the large parotid glands which cause bulky looking jawline.

Anti-wrinkle injections are effective, relatively affordable and offer little to no downtime. There are, however, some side effects associated with poorly performed procedures so it’s important to take time to properly choose your treatment provider based on relevant experience and reputation and not just on marketing hype or discounted pricing.

How To Choose Your Treatment Provider

People want to choose a clinician who can listen to them carefully and understand their concerns. Someone whose clinical skills deliver effective and hassle-free results with minimal discomfort or downtime.

We recommend that people should do their due diligence before choosing their treatment provider and not base their decision solely on the cheapest pricing in town. As the saying goes, you get what you pay for.
