Bunny lines sound cute. They rarely look that way in photos or in the mirror. Those little diagonal scrunch lines that appear along the sides of the nose when you smile or laugh can quickly become etched in, making the midface look tense, tired, or older than the rest of your features.
Botox for bunny lines is a small, highly precise treatment, but it sits in a very expressive area of the face. Done well, it softens the lines while keeping your smile natural. Done poorly, it can stiffen the nose and distort how the upper lip moves. That is why technique, dosing, and planning matter more here than the tiny surface area suggests.
This guide walks through how bunny line Botox actually works, what to expect step by step, and how it fits into a broader treatment plan that may also include botox for glabellar lines, botox for crow’s feet, and other expressions around the eyes and mouth.
What exactly are bunny lines?
Bunny lines are fine to moderate wrinkles that run diagonally from the bridge or side of the nose toward the inner corner of the eye when you scrunch your nose. They are most visible during expressions such as laughing, squinting, or smelling something strong. Over time, repeated movement can turn those dynamic wrinkles into static wrinkles that sit there even when your face is at rest.
Anatomically, bunny lines are mainly created by the transverse part of the nasalis muscle, with help from nearby muscles that lift the upper lip. When those muscles overwork, the skin over the nose creases in the same pattern, again and again.
In my experience, there are three common scenarios:
People who naturally scrunch their nose when they smile or laugh. People who never noticed bunny lines until after starting botox for frown lines or botox for crow’s feet, when their other wrinkles softened and the nose wrinkles suddenly stood out. People with very expressive midfaces who are starting preventative botox or baby botox treatment and want to keep lines from etching in.Whichever group you fall into, the principle is the same. Control the overactive muscle and you soften the lines.
Why Botox works for nose wrinkles
Botox is a neuromodulator. It temporarily blocks the nerve signal that tells the muscle to contract. With bunny lines, we are targeting a small portion of the nasalis and sometimes adjacent fibers of the levator labii superioris alaeque nasi (often called the “LLSAN”).
Softening those muscles reduces how deeply the skin folds when you make expressions. As the muscle relaxes over the next several days, the overlying skin gets a break from being repeatedly creased. In someone with newer, dynamic wrinkles, this often makes the lines essentially disappear at rest. In someone with older, more static wrinkles, Botox usually softens their depth and makes them harder to see, especially in photos, but may not erase them without additional help like microneedling, laser treatments, or careful use of dermal fillers.
Bunny line injections use very small doses compared with something like botox for forehead wrinkles or botox for jaw slimming. The goal is subtle botox results, not a frozen or “operated” look.
Who is a good candidate for bunny line Botox?
The best way to test yourself is simple. Look into a mirror, smile, and scrunch your nose as if a strong smell hit you. Then completely relax your face.
If the lines vanish when your face is at rest, you are dealing with dynamic wrinkles. These respond very predictably to botox for fine lines and wrinkles, often with quite low doses.
If the lines are still visible even when you are relaxed, some of the collagen and elastin in your skin has already remodeled to hold the crease. Botox will still help, but you may need repeated treatments and possibly complementary procedures, such as:
- gentle laser resurfacing or a light chemical peel to smooth texture targeted filler in the midface or nasolabial area to support lax skin a micro botox facial or skin booster approach if pore size and texture are also concerns
You should also be generally healthy, not pregnant or breastfeeding, and without any active skin infections around the nose or midface. If you have a history of unusual scarring, neuromuscular disorders, or prior complications with injectables, share that early in your consultation so your injector can plan around it.
How bunny line Botox fits with other facial treatments
Most patients who ask about bunny lines are not completely new to injectables. Very often they are already treating or at least thinking about:
- botox for glabellar lines between the eyebrows botox for crow’s feet around the outer eye botox for forehead wrinkles that appear when you raise your brows
Or they might be considering options around the mouth such as:
- botox for a gummy smile botox for lip flip to gently evert the upper lip filler or other treatments for nasolabial folds and marionette lines
The nose sits in the middle of this network of muscles. When you relax one group, another can sometimes compensate. A classic example is someone who has had strong treatment of the glabellar area and crow’s feet, then comes back saying “My nose wrinkles when I smile now, and it never used to.” The bunny lines were often there in a mild form, but other, stronger wrinkles attracted more visual attention. Once those are softened, the nose takes center stage.
This is where good botox treatment planning and botox facial mapping make a tangible difference. The injector needs to read your face like a whole system rather than a set of disconnected spots. For natural looking botox, your bunny line injections should complement whatever is happening above (forehead and brows) and below (upper lip and midface), so the final effect feels balanced and expressive, not patchy or “overdone” in one area.
The consultation: what a careful injector looks for
During a proper botox consultation process, I walk through four key things when assessing bunny lines.
First, I watch how the nose moves in real time. I ask you to smile, laugh, squint, snarl, and then fully relax. I am looking not only at the lines themselves, but how they interplay with your under eye wrinkles, glabellar activity, and crow’s feet.
Second, I check for asymmetry. Most people have one side that pulls a bit more than the other. If I see that, I know I may want slightly different dosing per side, rather than a “cookie cutter” number.
Third, I look at the rest of your treatment history. Have you had botox for frown lines, a brow lift with injectables, or a recent chemical peel? Are you using fillers in the midface or nose? Have you ever had surgical rhinoplasty? All of this informs where I can safely place the product.
Fourth, we go over your comfort level. Some patients want maximum softening and are happy to sacrifice a bit of scrunching. Others want to leave a touch of movement, especially if they are on camera a lot and rely on expressive micro-movements.
That conversation guides everything that follows, from product choice to dosage.
Step by step: what happens during bunny line Botox
The entire appointment for botox injections for beginners can be surprisingly quick, but there is a clear sequence that separates a rushed visit from a well planned medical treatment.
Here is what a typical bunny line session looks like in my practice:
- Cleaning and mapping. Your makeup is removed from the midface and nose, and the skin is cleansed with an antiseptic solution. I may use a cosmetic pencil to lightly mark the planned injection points on either side of the nose, usually two to three sites per side depending on your anatomy. Expression testing. Before any injections, I ask you once more to scrunch, smile, and relax. I palpate the muscle lightly with a gloved hand so I can feel exactly where it contracts most strongly. This double check helps with botox precision dosing and botox muscle targeting. Dosing and product choice. I decide on the number of units per injection point. Typical bunny line treatments use somewhere in the range of 2 to 5 units per side with standard Botox, though this can vary. Some injectors may use Dysport or Xeomin instead. The choice between botox vs dysport vs xeomin often comes down to personal injector experience, how fast onset you want, and what you have responded well to in the past. Injections. Using a very fine needle, I inject tiny amounts of toxin into each marked point. You may feel a brief pinch and mild pressure, but it is very quick. Most patients rate the discomfort around 2 or 3 out of 10 and do not need topical numbing. A single bunny line treatment usually takes under 5 minutes of actual injection time. Immediate post care. I apply gentle pressure with gauze if there is any pinpoint bleeding, then you can apply a cool compress if you are prone to swelling. At this stage, your nose will look essentially the same except for small raised “blebs” at each injection site, which flatten within 10 to 20 minutes.
You walk out with full movement, because botox does not work instantly. It typically begins to kick in after 3 to 5 days, with full effect around the 10 to 14 day mark. That botox results timeline is important, especially if you are scheduling around events or photos.
How many units, how often, and how long does it last?
Every face is different, but there are some general patterns.
For bunny lines specifically, I often start with a conservative dose for first time botox patients. That may look like 4 to 8 total units of Botox on the nose region. Men may need slightly more on average due to stronger musculature, but not always. The goal is to see how your muscles respond before committing to higher doses. You can always add a small touch up at the 2 week mark if needed.
As for durability, bunny line Botox usually lasts around 3 to 4 months. Some people hold results closer to 5 months, others start to see botox wearing off signs at 10 to 12 weeks, especially very expressive patients or those who do a lot of high intensity workouts.
How often should you get botox for bunny lines? A realistic maintenance plan for most patients is 3 to 4 treatments per year. If you are using preventative botox or baby botox treatment with very small doses, you might schedule closer to every 3 months to keep movement gently controlled instead of going through full cycles of “on” and “off.”
If you already treat multiple areas, such as botox for forehead wrinkles, botox for neck bands, or botox for TMJ pain, we usually coordinate bunny line touch ups with your broader schedule so you are not constantly in the chair.
What does it feel like afterward?
For most people, the recovery time from bunny line Botox is almost nonexistent. You might see:
- mild redness or tiny bumps at the injection sites that settle within an hour light pressure or tightness sensation around the nose as the product starts working over the next few days in some cases, a small bruise, especially if you are on blood thinners or supplements like fish oil or high dose vitamin E
You can go back to work, drive, and resume gentle daily tasks immediately.
Some people notice that their nose does not scrunch as easily when they smile or laugh. That is the point. However, your overall ability to express emotion should remain intact. If you ever feel your smile itself looks odd, stiff, or uneven, that is something to discuss with your injector. It can usually be addressed with small adjustments at your next visit.
Aftercare that actually matters
There is a lot of folklore on the internet about botox aftercare tips. The evidence based advice is simple and mostly about avoiding product migration and minimizing bruising.
Here is the concise version I share with patients:
- Stay upright for 4 hours after treatment. Avoid lying flat or bending deeply from the waist repeatedly during that window. Skip vigorous exercise, steam rooms, and very hot showers for the rest of the day to keep blood flow and pressure stable around the treated area. Do not rub, massage, or apply heavy pressure to the nose, bridge, or midface for 24 hours, including facials or certain facial devices. You can gently apply makeup after about 30 minutes, once the skin has calmed, but avoid pressing hard on injection points. If you bruise, a cold compress in short intervals and topical arnica can help.
Most importantly, give the treatment the full 2 weeks before judging the botox before and after results. Some muscles take the product a bit more slowly. If there is any asymmetry or under treatment at that point, a small touch up can usually fine tune the outcome.
Safety, side effects, and what can go wrong
Is botox safe for bunny lines? In healthy adults treated by trained injectors, it has a very good safety profile. The dose is low, and the injections are superficial.
Common, mild side effects include temporary redness, swelling, or bruising at the injection site. Some people experience a tension or “heavy” sensation in the area for a few days as the muscle relaxes, especially if they are new to botox injections for beginners.
Less common, but important, risks with nose injections include:
- Over treatment, which can make nose expressions look flat or cause the upper lip to move differently. This usually improves as the product wears off, but it is still better to avoid by starting conservatively. Asymmetry, where one side of the nose relaxes more than the other. This is usually correctable with a small extra dose on the stronger side. Spread to adjacent muscles, which might subtly affect how you flare your nostrils or smile. Good botox injection techniques and precise placement help minimize this.
Serious complications such as infection or allergic reaction are extremely rare but possible with any injectable. Choose a medical provider who understands both facial anatomy and botox risks and benefits, and who is able to manage complications if they arise.
If you are combining treatments, such as botox with dermal fillers, botox with laser resurfacing, or botox with chemical peel, timing and order matter. In many cases I prefer to place Botox first so that the muscles are calm when we do more structural work with fillers or energy devices. Your provider should walk you through a sequencing plan that fits your skin and schedule.
How bunny lines connect to the rest of your aesthetic plan
One of the biggest mistakes I see is treating bunny lines in isolation without thinking about the rest of the face.
For example, someone in their late 30s might come in for botox for bunny lines and botox for crow’s feet, but they also have very active forehead lines and a low set brow with early hooded eyes. In that case, a small botox eyebrow lift, also known as a subtle botox brow lift, might open the eyes gracefully, improve eye rejuvenation, and make the whole upper face look fresher. Treating only the nose wrinkles while leaving heavy glabellar lines and forehead creases untouched can look unbalanced.
Another patient might have a dimpled chin from overactive mentalis muscle and early marionette lines. They ask about nasolabial folds Additional resources and smile lines fillers yet hate how their nose wrinkles every time they smile. For them, a microdose of botox for dimpled chin and bunny lines, plus conservative filler around the mouth, can provide a smoother, more harmonious lower face.
I also frequently see bunny lines in patients dealing with functional issues like botox for TMJ pain, botox for teeth grinding, or botox for neck pain and shoulder tension where we treat the masseters, temples, or trapezius (trap tox). In those cases, the goal often includes facial slimming and facial contouring, not just wrinkle reduction. If we reduce masseter bulk, for instance, the midface can appear more sculpted, which may change how nose wrinkles draw attention. Subtle adjustments to bunny line dosing over time help maintain that balance.
What about skin type, age, and gender?
Bunny line Botox can work well across different skin types and ages, but expectations should be tailored.
Younger patients using botox for younger skin or as wrinkles prevention often see more dramatic smoothing because their lines are mostly dynamic and their collagen is still robust. A tiny “baby botox” dose on the nose a couple of times a year can keep creases from etching in, especially in people with thinner or more sensitive skin.
Patients with aging skin or deeper, static wrinkles may need more global support: hydration, sun protection, and sometimes procedures that stimulate collagen, such as microneedling or fractional lasers. Botox is excellent for dynamic wrinkles; it is not a magic eraser for all texture problems.
Men often have thicker skin and stronger muscles, which can mean slightly higher dosing to achieve the same level of softening. However, many male patients ask for very natural looking botox that preserves a rugged or expressive look. In those cases, a conservative approach with a focus on facial balance is better than chasing every line.
Bunny line treatment is also appropriate across a range of ethnicities and nasal shapes. The injection points may shift slightly to respect different nose contours, past rhinoplasty, or cultural aesthetic preferences, but the core principle is the same: soften overactive muscle while preserving the character of your smile.
Integrating bunny line Botox into long term care
Botox is not a one time fix. If you like the effect, you will likely repeat it. That can be a good thing if you use it strategically.
For long term anti aging, I usually look at a 12 to 24 month horizon. On that timeline, bunny line Botox is often paired with:
- intermittent botox for forehead wrinkles and glabellar lines, adjusted to maintain brow position and avoid heavy lids periodic treatments for crow’s feet and under eye wrinkles to keep the eye area bright occasional support for chin dimpling or neck bands if those muscles start to overact with age
We watch how your patterns shift over time. Some people naturally decrease a certain expression as life and stress change. Others develop new habits, such as frowning at screens or grinding their teeth, that call for updated plans.
A good botox maintenance plan evolves. It respects your facial identity, budget, schedule, and tolerance for procedures. Bunny line treatments are one small, precise piece of that puzzle, but when executed well, they can make a disproportionate difference in how relaxed and fresh your midface appears.
Bunny lines may be a small detail, yet in photos and in person, those tiny diagonal creases can broadcast tension and age more than you expect. With thoughtful assessment, precise dosing, and clear communication about your goals, botox for bunny lines can quietly smooth that area while keeping your smile uniquely yours.
