What Causes Bunny Lines?
Bunny lines are the diagonal lines that appear on the nose bridge when you smile or make certain facial expressions. These expression lines may seem subtle at first but can deepen over time due to muscle strength, sun exposure, and the loss of skin elasticity.
- Repeated muscle contractions - Frequent movement of the nasalis muscle, one of the small facial muscles that shape expression, leads to the formation of bunny lines.
- Natural ageing process - Over time, collagen production slows, making facial wrinkles more visible.
- Sun exposure - UV damage can break down skin elasticity and coarsen skin texture, contributing to deeper wrinkles.
- Botox migration from other treatments - In some cases, anti-wrinkle treatment for forehead lines, frown lines, or glabella filler can cause bunny wrinkles to become more pronounced, as the surrounding muscles compensate.
While topical skincare may help maintain skin health, Botox injections for bunny lines offer a more effective treatment for longer-lasting effects.
How to Get Rid of Bunny Lines
At PHI Clinic, we offer non-surgical cosmetic treatments for bunny lines that deliver subtle, natural-looking results while preserving facial features.
- Botox treatment in London – anti-wrinkle injections using botulinum toxin relax the nasalis muscle, preventing the formation of bunny lines while allowing normal facial movement.
- Dermal Fillers – for patients with deeper wrinkles or mild volume loss, hyaluronic acid fillers can smooth the skin and enhance facial contours.
- Medical-Grade Skincare – using collagen-boosting skincare helps maintain a smooth appearance and supports longer-lasting effects post-treatment.
For the best facial appearance, precise injection points matter as much as the number of units for bunny line Botox. Regular repeat treatments every 3 to 4 months help maintain consistent results.
What Are the Benefits of Bunny Line Botox?
Choosing Botox injections in London for bunny wrinkles is a quick, effective treatment that delivers visible improvements with minimal downtime.
- Softens facial wrinkles - Reduces bunny line wrinkles on the nose bridge.
- Prevents further wrinkle formation - Limits muscle contractions to prevent deeper lines from developing.
- Maintains natural expressions - Targets only the nasalis muscle, leaving other facial movements unaffected.
- Fast and convenient treatment process - A single session takes just 10 to 15 minutes, with normal activities resumed immediately.
- Longer-lasting effects - Results last 3 to 4 months, and the duration of effect often extends with regular treatment.
What to Expect from This Treatment?
Before your bunny line treatment, you'll have a treatment plan consultation at PHI Clinic built around a personalised approach. Your expert practitioner will assess your facial features, discuss your aesthetic goals, and determine the optimal dosage of Botox injectables to achieve a smooth, natural finish. Where bunny lines sit alongside other concerns, they can be treated at the same time as anti-wrinkle injections in London for the forehead or frown lines, as part of a full-face treatment plan for balanced facial rejuvenation.
The appointment itself is quick and virtually painless, taking just 10 to 15 minutes. Using fine needles, Botox is carefully injected into the nasalis muscle to relax the area and prevent diagonal lines from deepening. Most patients describe the sensation as a mild pinch. There's minimal downtime, meaning you can return to work or daily activities immediately. Full results develop within 7 to 14 days, creating a refreshed, smoother nose.
Aftercare and Recovery
Bunny line Botox requires little to no recovery time, but following post-treatment care is essential for optimal results. Mild side effects such as minor redness or swelling may occur but typically subside within a few hours.
Aftercare Instructions:
- Avoid touching or massaging the treated area for 24 hours to prevent Botox migration.
- Stay upright for four hours post-treatment to allow the product to settle properly.
- Avoid alcohol, intense exercise, and excessive heat exposure (saunas, hot showers) for 24 to 48 hours.
- Common side effects include mild bruising, but these typically fade within days after treatment.
- Results begin to appear within a few days, with full effects visible in two weeks.
- Regular repeat treatments help maintain a smooth, refreshed appearance.
