Anti wrinkle injectable treatment works by temporarily reducing the activity of the treated muscle, which softens the expression lines caused by repeated muscle movement. The effect is temporary and the muscle gradually returns to normal activity over 3 to 4 months.
Anti wrinkle injectable treatment is one of the most commonly performed cosmetic procedures in Australia and one of the most searched topics before a first consultation. Understanding how it works helps you make a more informed decision about whether it is appropriate for your situation and what to expect from the process.
The Mechanism: How It Works
Anti wrinkle injectable treatment uses a prescription medicine that temporarily reduces the activity of the treated muscle. The medicine works by blocking the chemical signal between the nerve and the muscle in the treated area. Without this signal, the muscle cannot contract as strongly, which reduces the repeated creasing of the overlying skin that creates expression lines.
The effect is temporary. The body gradually breaks down the medicine over a period of months and the muscle returns to its normal level of activity. This is why anti wrinkle treatment requires regular maintenance rather than being a one time procedure.
Which Lines It Addresses
Anti wrinkle treatment is most effective for expression lines, which are lines caused by repeated muscle movement. The most commonly treated areas are the forehead, where horizontal lines form from raising the brows, the glabella between the brows where frown lines develop from repeated concentration or frowning, and the outer corners of the eyes where crows feet form from smiling and squinting.
Anti wrinkle treatment is less effective for static lines that are present at rest regardless of expression, lines caused primarily by volume loss or skin laxity, and texture changes related to sun damage or skin quality. These concerns require different assessment and different approaches.

What Treatment Does Not Do
Anti wrinkle injectable treatment does not add volume to the face. It does not lift the skin. It does not remove lines that are already deeply established at rest. It does not permanently change the muscle and it does not affect skin quality. These distinctions are important for setting realistic expectations before a consultation.
At Core Aesthetics, Corey explains clearly at consultation what treatment can and cannot achieve for your individual face and the specific lines you are concerned about.
The Timeline: What to Expect
Anti wrinkle treatment does not produce immediate visible results. The effect develops gradually over the 7 to 14 days following treatment as the medicine takes full effect in the treated muscle. The full result is typically visible at two weeks.
Results last approximately 3 to 4 months for most clients before muscle activity gradually returns. Returning for maintenance treatment before the full effect has worn off tends to produce more consistent results over time. Read more about how long anti wrinkle treatment lasts.
The Clinical Importance of Individual Assessment
Because different people have different muscle strengths, different patterns of movement and different facial structures, anti wrinkle treatment is not a one dose fits all procedure. The appropriate dose and placement for your individual muscles is determined at consultation through direct assessment of your movement patterns and facial anatomy.
At Core Aesthetics, Corey assesses the full upper face before making any recommendation, including how different areas relate to each other and how treatment in one area may affect adjacent areas. This is why the consultation is the foundation of every appointment rather than a formality before proceeding to treatment.
