Nose Botox®: Utilizing Botox® for Nasal Enhancement

Last updated: September 2026

Nose Botox® has become one of the most requested non-surgical facial treatments, and one of the most misunderstood. Small doses of botulinum toxin placed around the nose can lift a tip that drops when a patient smiles, calm nostrils that flare during speech, and soften the fine lines that crease the nasal sidewall. What it cannot do is change bone or cartilage — and the difference between those two categories is where most patient disappointment begins.

Getting nasal treatment right depends less on technique than on knowing which muscle is doing the pulling. The nose sits at the meeting point of five muscles that also control the upper lip and the lower eyelid, so a dose placed a few millimetres off target can flatten a smile or drop a nostril. That is why nasal work is usually taught after the upper face in any structured curriculum, alongside broader facial injection-site anatomy.

This guide covers what the current literature supports: which muscle produces which nasal concern, the unit ranges and depths reported in published protocols, how long results actually last, the complications that matter, and a 2024–2026 anatomical finding that has changed how bunny lines should be injected.

Key Takeaways

What Nose Botox® Can and Cannot Do

Botulinum toxin is a muscle relaxant. It changes what moving muscles do to the overlying skin and soft tissue. It has no effect on the bony pyramid of the nose, the upper lateral cartilages, or the lower lateral cartilages that shape the tip at rest. A useful way to explain this in consultation: toxin can adjust how a curtain hangs when someone tugs the cord, but it cannot move the curtain rail.

That distinction sorts almost every nasal request into one of two piles.

Patients asking about narrowing generally mean one of two different things, and separating them in consultation prevents an unhappy review. Reducing dynamic flare is achievable; reducing resting width is not. Our companion guide on Botox® for a wide nose works through that conversation in more depth.

The Muscles Behind the Nose

Five muscles account for nearly all of the nose’s dynamic appearance. Naming the right one is the whole job — the injection itself is straightforward once the target is correct.

Injection Areas, Doses and Depth

Nasal doses are among the smallest on the face. The muscles are thin, superficial and close to the elevators of the upper lip, so low volume and high concentration are the rule. Reconstituting with 1 mL of preservative-free saline per 100-unit vial and using a 0.3 mL syringe with a 30G needle keeps the injected volume — and therefore the spread — as small as possible.

Tiering a tip lift

Published nasal protocols commonly treat the tip in graded tiers rather than as a single fixed dose, pairing the depressor septi nasi with the dilator naris on each side so the tip lifts without the nostrils appearing pinched:

• Soft lift — approximately 6 U total: 2 U into each dilator naris plus 2 U into the depressor septi nasi.
• Medium lift — approximately 12 U total: 4 U per point.
• Strong lift — approximately 18 U total: 6 U per point.

Start at the lower tier. Under-treating a nose is a two-week fix; over-treating it affects speech, smile symmetry and nostril position for months. A conservative first session also gives the practitioner a movement baseline to titrate against at the follow-up, the same principle that governs how often patients should return for repeat Botox® across every treatment area.

Gummy smile and the LLSAN

The levator labii superioris alaeque nasi is the connecting muscle between the nose and the upper lip, which is why nasal treatment often changes a patient’s whole smile. A retrospective series of 227 patients treated with a global facial pattern including the nasal muscles reported improvement in tip droop and a shortened lip philtrum on smiling alongside the expected upper-face effects. Where excessive gum show is the primary concern rather than an incidental finding, the dedicated gummy smile Botox® protocol is the better starting point.

What Changed in 2024–2026: the “Bunny Triangle”

For decades, bunny lines were treated by injecting directly into the visible crease on the nasal sidewall. That assumption has now been tested and found wanting.

A study published in Clinical Anatomy combined 39 cadaveric dissections with dynamic ultrasound in 13 living volunteers, examining the area between the medial canthus and the nasal dorsum. It found no discrete muscle beneath the wrinkle. Instead there is a consistent non-muscular interval — the “bunny triangle” — bordered by the procerus superomedially, the transverse nasalis superolaterally, the LLSAN inferomedially, and the medial fibres of the orbicularis oculi laterally. Under ultrasound during nose-scrunching, the visible wrinkle was skin folding over that gap while the surrounding muscles contracted at its edges.

The analogy is a tablecloth that wrinkles in the middle because four people are tugging the corners. Pressing on the wrinkle achieves nothing; you have to address the tugging.

A follow-up commentary in the Journal of Cosmetic Dermatology (January 2026) translates the anatomy into a border-targeted protocol: assess the patient dynamically first by asking them to smile, scrunch the nose and express disgust, identify which border contracts most prominently, then treat that border rather than the line. The transverse nasalis takes 1–2 units along its superior border as the primary driver; the LLSAN takes a 0.5–1 unit micro-aliquot at its superomedial border, placed cautiously to avoid alar ptosis or weakening the lip elevators; the medial orbicularis oculi receives a conservative dose at the medial canthal border when lateral traction dominates; and the procerus takes 1 unit at its inferolateral margin if glabellar contraction extends into the nasal root. Depth is 1.5–2.0 mm in the subcutaneous plane, with the angular artery as the structure to avoid.

The same paper notes that repeated high-dose injection into non-muscular tissue may raise the risk of antibody formation over time, reducing long-term responsiveness. That is an argument for precision rather than volume. Our separate guide to bunny lines Botox® covers patient-facing expectations for this treatment area.

Every Nasal Use of Botox® Is Off-Label

Botox® Cosmetic carries four FDA-approved aesthetic indications: moderate to severe glabellar lines, lateral canthal lines, forehead lines, and platysma bands. Nothing on that list is nasal. Treating a drooping tip, nasal flare, bunny lines or alar elevation is therefore an off-label application.

Off-label is not a warning label. It describes a use supported by published literature and clinical practice rather than by a manufacturer’s approved indication, and it is routine across aesthetic medicine. What it does require is that the patient be told, in plain language, during consent — and that the practitioner be able to point to the evidence base. A 2024 systematic review screened 1,139 papers and included 23, concluding that botulinum toxin can correct drooping nasal tips, dilated nostrils, minor post-rhinoplasty deformities and high columellar show, and describing it as a safe and effective option for minor nasal defects.

In August 2026 Allergan Aesthetics announced FDA acceptance of a supplemental application for masseter muscle prominence, which would become the fifth approved aesthetic indication. No nasal indication is currently under review.

How Long Nose Botox® Lasts

Roughly three to four months, depending on the target. The depressor septi nasi is generally reported to wear off sooner than other facial areas, which patients should be told before the first session so the shorter interval does not read as a failed treatment.

The figure of “six to twelve months” that circulates for non-surgical nose treatments is a filler duration. Applying it to botulinum toxin sets an expectation no toxin can meet and is a common source of complaints at the three-month mark.

Risks, Complications and Danger Zones

The nose is a small target surrounded by muscles that do important work. Most nasal complications are diffusion complications — the right drug in almost the right place.

• Asymmetric or flattened smile — toxin reaching the levator labii superioris or the wider lip elevator group.
• Upper lip ptosis or elongation — most often from lateral spread at the depressor septi nasi.
• Labial sphincter incompetence — diffusion into orbicularis oris, affecting speech, whistling, drinking from a cup.
• Alar ptosis — over-treatment or misplacement at the LLSAN.
• Exaggerated nostril opening — reported with high doses at the tip complex.
• Diplopia — rare, from unintended involvement of the inferior or medial rectus after injection high on the nasal sidewall.
• Tearing — orbicularis oculi involvement near the medial canthus.
• Vascular events — the angular artery runs close to the nasal sidewall injection points. This is a catastrophic rather than cosmetic risk, and it is the reason superficial, low-volume placement matters here more than almost anywhere else on the face.

Two habits prevent most of these: stay superficial where the protocol says superficial, and keep the injected volume small. Practitioners mapping the surrounding territory should review the facial danger zones for the mid-face before treating the nose for the first time.

Botox® and Fillers Are Not Interchangeable Here

“Non-surgical rhinoplasty” and “liquid rhinoplasty” describe the injection of hyaluronic acid filler to add structure — camouflaging a dorsal hump, straightening a profile line, projecting a tip. It is not a device procedure, and it is not what toxin does. Toxin softens movement; filler adds volume. A patient who wants a bump smoothed is asking for filler or surgery, not for toxin.

Injectable liquid silicone is a separate matter and is not a cosmetic option. The FDA states that silicone injections can lead to long-term pain, infections and serious injuries including scarring, permanent disfigurement, embolism, stroke and death. Patients occasionally present having had it done elsewhere; it should never be offered.

Beyond injectables, a 2024 review of non-surgical nasal options reported volumetric reduction of the nose (excluding the tip) with radiofrequency microneedling lasting roughly twelve months on 3D imaging, and nasal reshaping with a 1470 nm laser after two sessions. These are early findings rather than established practice, but they are worth knowing when a patient’s goal is structural and toxin is not the answer.

Nose Shape and Realistic Expectations

Patients arrive with vocabulary borrowed from the internet — Roman, Greek, snub, hooked, button, aquiline, bulbous. These are descriptive labels for the resting shape of bone and cartilage, and none of them is a treatment indication. The practical value of the conversation is to separate what the patient sees in a still photograph from what they see in a mirror while talking.

A useful consultation sequence: photograph at rest, then photograph on full smile, and show the patient both. If the concern is visible only in the second image, toxin is likely to help. If it is equally present in the first, the honest answer is that toxin will not change it, and that saying so is what protects the relationship. Structured facial analysis makes that assessment repeatable rather than intuitive.

Frequently Asked Questions

Is nose Botox® FDA-approved?

No. Botox® Cosmetic is FDA-approved for four aesthetic areas only: glabellar lines, lateral canthal lines, forehead lines and platysma bands. Every nasal application — droopy tip, nasal flare, bunny lines, alar elevation — is an off-label use. Off-label does not mean unsafe or improper; it means the technique is supported by published literature and clinical experience rather than by a manufacturer’s approved indication, and patients should be told so during consent. In August 2026 Allergan filed for a fifth aesthetic indication covering masseter muscle prominence; nothing nasal is currently under review.

How many units of Botox® are used in the nose?

Nasal doses are small. Published protocols use roughly 2 to 4 units at the depressor septi nasi for a droopy tip, 5 to 10 units total divided between both sides for excessive nasal flare at the dilator naris, and 1 to 2 units per point at the transverse nasalis for bunny lines. Layered tip-lift protocols run from about 6 units for a soft lift up to 18 units for a strong one. Doses well above these ranges are not supported by the literature and raise the risk of lip and nostril complications.

Can Botox® make a wide nose narrower?

Only in a limited, dynamic sense. Botulinum toxin can reduce how far the nostrils flare during animation by relaxing the dilator naris, which makes the lower third of the nose look narrower when the patient smiles or speaks. It cannot change the width of nasal bone or cartilage, so a nose that is structurally wide at rest will still be wide at rest. Patients seeking a change to the underlying framework need surgical rhinoplasty.

How long does nose Botox® last?

Around three to four months for most nasal targets. The depressor septi nasi is generally reported to wear off sooner than other facial areas, while bunny lines treated at the nasalis may hold four to five months. The figure of six to twelve months sometimes quoted for non-surgical nose treatments refers to hyaluronic acid filler, not botulinum toxin, and should not be applied to toxin results.

Why do bunny lines sometimes not respond to Botox®?

Because the wrinkle itself may not sit over a muscle. A 2024 study combining 39 cadaveric dissections with dynamic ultrasound found that the area beneath bunny lines is a non-muscular interval, since named the bunny triangle, bordered by the procerus, transverse nasalis, levator labii superioris alaeque nasi and medial orbicularis oculi. Injecting into the crease therefore deposits toxin into connective tissue and relies on passive diffusion to reach muscle, which produces unpredictable results. Current guidance is to treat the contracting muscle borders instead of the line.

Is Botox® or filler better for the nose?

They do different jobs, and the safety profiles are not comparable. Toxin softens movement — a tip that drops on smiling, nostrils that flare, lines that crease. Filler adds structure, which is what non-surgical rhinoplasty actually is. The FDA lists the nose among the sites where it recommends against using dermal fillers, citing accidental injection into a blood vessel with reported necrosis, vision abnormalities including blindness, and stroke. The nose has limited blood supply and a dense arterial network, which is why it is one of the highest-risk areas on the face for filler.

Building Confidence with Nasal Injections

Nasal treatment rewards precision over volume. The doses are small, the anatomy is layered, and the muscles involved also control the smile — which is why practitioners who are comfortable in the glabella and forehead often hesitate at the nose. The fastest route past that hesitation is supervised practice on live models, where the feel of contacting bone at the subnasale or staying at 2 mm on the nasal sidewall becomes muscle memory rather than a diagram.
