Bunny lines treatment at Core Aesthetics uses prescription anti-wrinkle injectable product to temporarily reduce activity in the nasalis muscle, softening the diagonal or horizontal lines that appear on either side of the nose with expression. Treatment is individually assessed and is typically conservative in dosage.
Bunny lines are the diagonal or horizontal creases that appear on either side of the nose when smiling or scrunching. They are created by the nasalis muscle, which compresses and wrinkles the nose with certain expressions. For many people they are a minor concern noticed mainly in photographs. For others, particularly those who have had other upper face anti-wrinkle treatments that cause the nasalis to compensate with more visible activity, they become a more prominent feature worth addressing.
At Core Aesthetics in Oakleigh, bunny lines treatment is assessed by Corey Anderson, AHPRA registered nurse (NMW0001047575), as part of a broader upper face assessment. It is a relatively straightforward treatment area requiring conservative dosing, but it is still assessed individually to ensure placement is appropriate for your anatomy.
What Causes Bunny Lines?
Bunny lines develop from repeated contraction of the nasalis muscle, which runs across the bridge and sides of the nose. With expression, particularly scrunching or intense smiling, this muscle contracts and creates short folds in the skin on either side of the nasal bridge. Over time and with age-related reduction in skin elasticity, these creases can become visible even at rest.
One particular pattern worth knowing: bunny lines sometimes become more noticeable following anti-wrinkle treatment to the glabella (frown lines) or forehead. When the muscles in those areas are reduced in activity, the nasalis can compensate by contributing more visibly to expression, making previously subtle lines more prominent. This is a common reason clients return to discuss treatment of this area after an initial upper face treatment appointment.
How Bunny Lines Treatment Works
Bunny lines treatment uses a prescription injectable product to temporarily reduce the activity of the nasalis. Small, precise injections at the appropriate placement on either side of the nasal bridge soften the lines that appear with expression without affecting normal nasal function or appearance at rest.
The dosage for bunny lines is typically small relative to other treatment areas. Over-treatment in this area can produce an unnatural appearance, which is why conservative dosing and precise placement matter. Your practitioner will assess your nasalis activity and line distribution during your consultation and explain what realistic improvement looks like for your individual face.
Bunny Lines and the Upper Face Plan
Bunny lines are most commonly discussed alongside other upper face treatments at Core Aesthetics, including frown lines, forehead lines and crows feet. Understanding the full picture of your upper face expression and how different muscles interact allows for a treatment plan that produces a cohesive, natural result rather than addressing one area while inadvertently emphasising another.
