What the concern is:
Bunny lines are the fine diagonal or horizontal wrinkles that form along the sides of the nose, most noticeable when smiling, laughing, or scrunching the nose. In some individuals, these lines become more prominent over time and may remain visible even at rest.
Why they develop:
Bunny lines are caused by repeated contraction of the nasalis muscle and, in some cases, contributions from nearby facial muscles. Over time, repetitive movement combined with changes in skin elasticity allows these dynamic lines to become more defined.
How the treatment works:
Botox works by selectively relaxing targeted portions of the nasalis muscle. By reducing excessive muscle contraction, the skin along the nasal sidewall appears smoother during expression. Injection placement and dosing are carefully adjusted to maintain natural facial movement and avoid affecting nearby muscles involved in smiling or breathing.
What the treatment can do:
Soften fine wrinkles along the sides of the nose
Reduce the appearance of nasal scrunching lines during expression
Create a smoother transition between the nose and cheek area
Maintain natural facial movement when conservatively dosed
What the treatment cannot do:
Eliminate deep static lines caused by significant skin thinning
Replace skin resurfacing or volume-based treatments
Correct nasal shape or structural concerns
Anatomical and safety considerations:
The nasalis muscle lies close to other muscles involved in facial expression and nasal function. Precise injection depth and placement are essential to avoid unwanted diffusion into surrounding muscles. Conservative, anatomy-guided treatment helps preserve natural expression and function.
Who this treatment is best for:
Patients bothered by wrinkles that appear when smiling or scrunching the nose
Individuals seeking a subtle refinement rather than a dramatic change
Those who value physician-guided, conservative treatment
Patients who may benefit from combination treatment with crow’s feet or upper-face Botox for balanced results
The goal:
The goal of Botox for bunny lines is to gently reduce excessive muscle activity while preserving natural facial movement. Treatment is designed to soften expression-related wrinkles and maintain overall facial harmony without drawing attention to the area.
