Why Do Bunny Lines Appear?
A mix of factors contribute:
- Natural facial expressions and repetitive muscle movements that crease the same spot repeatedly
- Ageing and reduced collagen, which weakens skin texture and elasticity
- Previous Botox injections in the forehead or crow’s feet area, which can sometimes make the nasalis muscle more active as it compensates
It’s completely normal, but if static wrinkles are becoming deeper or more noticeable, non-surgical treatments can help.
How Bunny Lines Are Treated
Bunny lines are treated with small, precise doses of anti-wrinkle injections (botulinum toxin, a prescription-only medicine) placed into the nasalis muscle on each side of the nose. The nasalis is the muscle that contracts when you scrunch your nose, and over time the repeated folding of the skin above it etches the diagonal lines we call bunny lines.
The aim of treatment is not to freeze the nose completely, but to soften the strength of the muscle just enough that the lines stop creasing as deeply, while still allowing natural movement and expression.
What treatment involves
The treatment itself is quick, usually taking less than 15 minutes:
- A consultation and assessment of how your nose moves when you smile and scrunch
- Marking the injection points where the strongest lines form
- A small number of injections into the nasalis muscle on each side
- No downtime, with most people returning to normal activities straight away
You may feel a brief pinprick at each point, and mild redness or swelling can occur but usually settles within hours. Results begin to appear within a few days, with the full effect visible at around two weeks. Most people find their results last three to four months.
Typical dosing
Bunny lines need only a low dose compared with larger areas like the forehead. As a general guide, treatment typically uses around 2 to 4 units of botulinum toxin per side of the nose, so roughly 4 to 8 units in total. The exact dose is always individualised, depending on how strong your nasalis muscle is and how pronounced your lines are.
This is why an in-person consultation and assessment matters. The right dose is the smallest amount that softens the lines while keeping your expression natural. Too much, or placement that is too low and lateral, risks affecting nearby muscles and changing the appearance of your smile, which is why precise, anatomy-led injecting is so important.
Why bunny lines sometimes appear after other Botox treatment
Some people first notice bunny lines after having anti-wrinkle treatment in other areas, such as the frown lines or crow's feet. This is not the treatment "causing" new lines. When the muscles around the eyes and brows are relaxed, the body subconsciously recruits the nasalis muscle a little more, which can make bunny lines more noticeable. Treating the nasalis rebalances this, which is why bunny lines are often treated alongside other areas.
Is It Safe?
Yes. When carried out by trained medical professionals, Botox for bunny lines is considered very safe. At Oracle Clinics, your treatment will always be performed by an experienced practitioner like Nurse Ness Abbey who understands facial anatomy, injection sites, and how facial muscles respond to botulinum toxin.
The amounts used are very small, targeted, and designed to look natural. Side effects are minimal and some people notice mild redness or a small bruise at the injection site, but this usually fades quickly with basic post-treatment skin care.
How Long Do Results Last?
Most patients see results starting within a few days, with the full effect visible at two weeks. Results typically last three to four months, after which you can choose whether to maintain them with top-up anti-wrinkle injections.
Over time, as the muscle movement relaxes, lines appear less deeply even without treatment. For longer-term facial rejuvenation, non-surgical treatments such as skin boosters can also support collagen production and overall skin health.
Who Is Bunny Line Treatment For?
This treatment may be right for you if you’ve noticed:
- Fine wrinkles across the bridge of your nose when you smile
- Creases that linger even when your face is at rest (static wrinkles)
- Lines that seem more noticeable after other cosmetic treatments
- A desire for fresher, more balanced expressions
It’s suitable for both women and men and works well as part of a broader skin care and skincare routine. Combining Botox injections with facial exercises, dermal fillers, or non-surgical treatments can provide a comprehensive approach to facial rejuvenation.
