Those diagonal creases that fan out across the sides of your nose when you laugh or scrunch your face. That's what the aesthetics world calls bunny lines. They sit just below the nose bridge, angling down toward the cheeks, and they show up because of a muscle most people have never heard of: the nasalis.
Bunny lines Botox is one of the more underrated treatments for the nose area. Not as talked about as lip flips or brow lifts, but surprisingly fast, low-unit, and effective for patients who want to smooth that area without touching anything else on the face.
All botulinum toxin products carry an FDA Boxed Warning about the potential for toxin effects to spread beyond the injection site; at cosmetic doses, this is rare, but your provider will review this with you before any Botox-based treatment.
Bunny lines Botox is an off-label use of botulinum toxin. Your provider will explain what that means at your consultation.

What are bunny lines and what causes them?
Bunny lines are diagonal wrinkles that appear on the upper sides of the nose when someone laughs, squints, or scrunches their face. The name comes from the way rabbits twitch their noses, and the movement and the lines do look similar.
They're caused by the nasalis muscle, specifically its transverse portion, which compresses the nasal aperture during strong facial expressions. Every contraction produces that fold across the nasal sidewall. Over time, skin that has been folded repeatedly starts to show the crease even at rest, which is when most patients decide to do something about it.
Some patients develop prominent bunny lines after Botox in the glabellar region. When Botox relaxes the corrugator and procerus muscles, surrounding muscles can compensate by working harder during expression, and the nasalis is one of them. If you've treated your 11 lines and noticed lines appearing on the sides of your nose that weren't as obvious before, that's probably what's happening.
How many units of Botox for bunny lines?
Clinical dosing for bunny lines runs 3 to 5 units per side, injected into the lateral nasal sidewall. Total treatment is 6 to 10 units for both sides. (Dermatology: Nose, Lips, and Perioral Region, MDEdge, Carruthers et al.)
Injection placement matters more than unit count for this area. Target the transverse nasalis on each side. The nasolabial sulcus is deliberately avoided. Going too close can relax the levator labii superioris alaeque nasi, which lifts the upper lip. That's not the intended outcome.
Bunny lines rank among the lowest-unit Botox treatments on the face. By comparison, the glabellar region uses 20 to 30 units. That makes bunny lines an easy add-on at a session already covering forehead, 11 lines, or crow's feet, with minimal added cost.
What does bunny lines Botox cost in Jacksonville?
At New Day Medspa, Botox starts at $8.99 per unit, with no package fees or hidden room charges.
Most patients treat bunny lines alongside another area in the same session. Adding 6 to 10 units onto an existing upper-face appointment adds between $53 and $90. There's no separate consultation fee. We assess how many units your nasalis activity warrants during your appointment.
Financing is available through Cherry, PatientFi, Afterpay, and Klarna for patients combining multiple areas or managing treatment costs across several visits.
Expert tip: Patients who get bunny lines after starting glabellar Botox should mention this at their next consultation rather than waiting and wondering. Adding a small amount to the nasalis at the same session as 11 lines treatment is often enough to keep the compensation pattern from developing further. Starting with 3 units per side at the first bunny lines session, then reassessing at two weeks, is the standard approach for new patients.

Bunny lines Botox before and after: what to expect
The results timeline for bunny lines Botox follows the same pattern as other small facial muscles.
Day 1 to 3: No visible change. The injection sites may be slightly tender. The product hasn't taken effect yet.
Day 3 to 5: Early softening of movement. The crease becomes less dramatic during expression.
Day 7 to 14: Full effect. The nasalis is relaxed. The lateral nasal sidewall stays smooth during expression. Patients who had etched-in lines at rest see marked softening at this stage.
Week 2 to 3: Peak result. Lines that only appeared during expression are often invisible. Deeper static lines soften, though they may not fully erase from a single session.
Month 3 to 4: Muscle activity gradually returns. Most patients return to their baseline by the 3-month mark.
For patients who developed bunny lines as a compensation pattern after glabellar Botox, treating both areas in the same session means both results arrive and wear off on roughly the same timeline, which makes scheduling simpler.
Does bunny lines Botox affect the nose or upper lip?
Done correctly, no. The target muscle is the transverse nasalis, which sits along the lateral nasal sidewall away from the lip. Placement technique matters: injecting too close to the nasolabial sulcus can unintentionally affect the levator labii superioris alaeque nasi, the muscle that lifts the upper lip. An experienced provider works specifically to avoid that.
This is why bunny lines treatment isn't DIY territory. The anatomical margin between the nasalis injection point and the nearby lip muscle is small. At 3 to 5 units per side, the total volume is low. Placement accuracy can make the difference between a clean result and an unintended one.
Who is a good candidate for bunny lines Botox?
Most patients who are candidates for facial Botox generally are candidates for bunny lines treatment. A few specifics worth knowing:
Patients who have already had glabellar or forehead Botox and noticed new nasal sidewall lines afterward are often the best-fit candidates, because the compensation pattern is already established and the intervention is straightforward.
Patients with moderate to strong nasalis activity during expression are good candidates. Lines that only appear during full expression respond quickly. Deeply etched static lines may respond more slowly and sometimes benefit from combining Botox with a small amount of hyaluronic acid filler for the residual crease. That's a separate conversation based on what the provider sees at assessment.
Patients under 30 with mild bunny lines that only appear during laughing are sometimes better served by waiting, since the lines aren't creating a resting-state concern yet. Most providers will say so at a consultation rather than proceed.
