Anti-wrinkle treatments are nonsurgical injectable prescription treatments that temporarily reduce the activity of specific facial muscles to soften the appearance of expression lines. In Australia they are regulated by the TGA and may only be prescribed and administered by a qualified health practitioner.

Anti-wrinkle treatments are among the most widely used nonsurgical cosmetic procedures in Australia. They work through a specific, well-understood mechanism and, when planned properly by a qualified practitioner, can produce natural looking results with minimal downtime. Understanding what they are and how they work is an important first step before considering whether they may be appropriate for you.

At Core Aesthetics in Oakleigh, all anti-wrinkle treatments are individually assessed and administered by a qualified health practitioner. Treatment is only discussed and recommended following a clinical consultation. You can explore our full anti-wrinkle treatments overview for more on our approach.

How Anti-Wrinkle Treatments Work

Anti-wrinkle treatments use a prescription injectable product derived from a purified protein to temporarily reduce the activity of targeted facial muscles. When injected into a specific muscle, the product temporarily blocks the nerve signals that cause the muscle to contract. The muscle relaxes, and the overlying skin, which would otherwise be repeatedly folded by muscle movement, has less opportunity to crease.

The effect is not permanent. Nerve signalling gradually recovers over weeks to months, and muscle activity returns to normal. This is why anti-wrinkle treatment needs to be repeated to maintain its effect.

What Anti-Wrinkle Treatments Are Used For

The most common treatment areas in facial aesthetics include:

  • Forehead lines: horizontal creases created by repeated upward movement of the brows
  • Frown lines: vertical creases between the brows from repeated brow furrowing
  • Crows feet: lines that fan from the outer corners of the eyes with smiling and squinting
  • Masseter: reducing jaw muscle bulk to slim the lower face or address clenching and grinding

Treatment may also be discussed for other areas where relevant to your individual concerns, following a clinical assessment.

Anti-Wrinkle Treatment in Australia, Regulatory Context

In Australia, the products used in anti-wrinkle treatment are classified as prescription medicines by the Therapeutic Goods Administration (TGA). They may only be prescribed and administered by a qualified health practitioner. This means that a clinical consultation and individual assessment are required before any product is used.

The TGA also restricts the advertising of specific prescription product brand names in consumer-facing material. This is why reputable clinics, including Core Aesthetics, refer to the category of treatment rather than brand names when communicating with the public. The specific product used is discussed openly during your individual consultation.

What Anti-Wrinkle Treatments Cannot Do

Anti-wrinkle treatments address expression lines by reducing muscle movement. They do not add volume, tighten skin or address concerns that are structural or volume related in origin. Where a concern is driven by volume loss, such as hollowing in the cheeks or a softened jaw border, dermal filler is the more appropriate approach. Many clients benefit from a combination of both, and this can be discussed during your consultation at Core Aesthetics.

Frequently Asked Questions

What do anti-wrinkle treatments treat?

Anti-wrinkle treatments are used to address expression lines in areas of repeated facial muscle movement. Common areas include forehead lines, frown lines, crows feet and the masseter. Suitability for each area is assessed individually during a consultation.

How long do the effects last?

Duration varies between individuals and between treatment areas. Your practitioner will discuss realistic timeframes specific to your treatment during your consultation.

Are anti-wrinkle treatments safe?

Anti-wrinkle products are prescription medicines regulated by the TGA in Australia. They should only be administered by a qualified health practitioner following an individual clinical assessment. Risks are explained clearly during your consultation.

Can anyone have anti-wrinkle treatment?

Suitability is assessed individually during a consultation. Certain medical conditions and medications may affect whether treatment is appropriate. Pregnancy and breastfeeding are contraindications.

What is the difference between anti-wrinkle treatment and dermal filler?

Anti-wrinkle treatment reduces muscle activity to soften expression lines. Dermal filler adds volume and structural support. They address different concerns and may complement each other in a broader treatment plan.

Are anti-wrinkle treatments the same as Botox?

Botox is a brand name for one type of product used in anti-wrinkle treatment. The TGA restricts advertising of specific prescription brand names in consumer material. The specific product used is discussed openly during your individual consultation at Core Aesthetics.
