Nose wrinkles, often called bunny lines, are the diagonal or vertical creases that appear on the sides of your nose when you laugh, scrunch, or squint. They form from repeated contractions of the muscle that runs along each side of the nose, and over time, sun damage and collagen loss can etch them into the skin permanently. Getting rid of them ranges from daily topical treatments to quick in-office procedures, depending on how deep the lines are and how much you want to invest.
Why Nose Wrinkles Form
The main culprit is a small muscle called the nasalis, which contracts every time you scrunch your nose, express disgust, or even smile broadly. But it doesn’t act alone. Several neighboring muscles around the inner eye, the area between your brows, and the upper lip all pull on the thin skin over the nasal bridge. A 2024 cadaveric and ultrasound study confirmed that a triangle of especially thin, non-muscular skin sits between these muscles. Because there’s so little padding in that zone, the repeated tugging from all directions creases the skin faster than in thicker areas of the face.
UV exposure accelerates the process significantly. Sunlight breaks down collagen and elastin, the proteins that keep skin bouncy enough to snap back after a facial expression. The nose is one of the most sun-exposed parts of the face, which is why bunny lines can show up earlier than wrinkles elsewhere.
Topical Retinoids for Shallow Lines
If your nose wrinkles are fine and mostly visible during expressions, a prescription retinoid is the most evidence-backed topical option. Tretinoin increases collagen production and improves skin thickness, elasticity, and overall texture. Clinical studies show initial improvements become visible after about four weeks of regular nightly application, with continued gains over several months. It works best on fine lines rather than deep-set creases.
Start with a low concentration two to three nights per week, since the nose can be sensitive to irritation. Flaking and redness are common in the first few weeks but typically subside. Pairing a retinoid with a simple moisturizer and daily sunscreen prevents the irritation from stalling your routine.
Neurotoxin Injections
For wrinkles that are clearly visible at rest or that bother you during expressions, neurotoxin injections (commonly known by the brand name Botox) are the most targeted fix. A provider will ask you to smile, scrunch your nose, and make a disgust face to map exactly which muscles are pulling hardest. This matters because the pattern varies from person to person.
Treatment typically involves tiny doses of 1 to 2 units injected along the upper border of the nasalis muscle on each side of the nose. If neighboring muscles contribute, your provider may add micro-doses of 0.5 to 1 unit at specific points near the inner eye or upper lip elevator. The total for both sides usually falls between 5 and 12 units, which translates to roughly $100 to $720 depending on your location, the injector’s experience, and per-unit pricing (typically $10 to $30 per unit nationally).
Results appear within a few days and last three to four months. You can return to work and normal activities immediately. For the first 12 hours, avoid rubbing the area or lying flat, and skip intense exercise for 24 hours. Common side effects are mild: slight redness, swelling, or bruising at the injection site, occasionally a headache. The main risk specific to this area is that toxin can spread to nearby muscles if too much volume is injected, potentially causing a droopy upper lip or slight asymmetry. This is why experienced injectors use high-precision, low-volume micro-doses rather than larger diluted amounts.
Dermal Fillers for Deep Creases
When bunny lines have become etched grooves that remain visible even when your face is completely relaxed, hyaluronic acid fillers can plump the skin from underneath. A small amount of filler is placed along the nasal sidewall to smooth the crease. Results typically last 6 to 18 months, depending on the product used and your metabolism.
Hyaluronic acid fillers have a built-in safety advantage: if the result isn’t right, they can be dissolved immediately with an enzyme injection. This reversibility is a key reason most providers prefer them over other filler types for the nose area, where precision matters and complications from alternative materials have been reported at higher rates.
Fillers and neurotoxin injections are often combined. The toxin relaxes the muscle so it stops deepening the crease, while the filler fills in the existing line. Together, they address both the cause and the visible damage.
Microneedling and Laser Resurfacing
Both microneedling and fractional laser treatments stimulate new collagen by creating controlled micro-injuries in the skin. Clinical trials comparing the two found no significant difference in wrinkle reduction or patient satisfaction. Both produced substantial improvement in fine lines and skin texture.
Where they do differ is in recovery and cost. Microneedling had noticeably shorter recovery time and slightly less swelling. Fractional laser treatments cost roughly three times more. For most people dealing with superficial nose wrinkles, microneedling offers comparable results at a lower price with less downtime. A series of three to six sessions, spaced four to six weeks apart, is typical.
Daily Sun Protection
No treatment will hold up without consistent sun protection. UV radiation is the single biggest accelerator of wrinkle formation on the nose, and it’s also the most preventable. Use a broad-spectrum sunscreen with SPF 15 or higher every day, even on cloudy days. The FDA specifically calls out the nose as an area that needs liberal application because of its prominence and constant exposure.
Reapply at least every two hours, and more often if you’re sweating or swimming. A full body application for an average adult takes about one ounce (a shot glass worth), but for daily life, focus on making sure the face and nose get thorough, even coverage. Sunglasses and wide-brimmed hats add another layer of protection, since no sunscreen blocks UV radiation completely. Limiting direct sun exposure between 10 a.m. and 2 p.m., when rays are strongest, makes the biggest difference of all.
Do Facial Exercises Help?
Facial yoga and nose-scrunching exercises are widely promoted online, but the evidence behind them is thin. The most recent clinical research on face yoga acknowledges that the field is “just beginning to sprout,” with most studies relying on subjective self-assessments rather than objective measurements. Available trials lack control groups, making it impossible to separate the effects of the exercises from other factors like skincare changes or placebo. For wrinkles caused specifically by repeated muscle contraction, deliberately exercising those same muscles could theoretically reinforce the creasing pattern rather than reduce it.
Choosing the Right Approach
The best option depends on how deep your lines are and what you’re willing to commit to. Fine lines that only show during expressions respond well to a consistent retinoid routine, daily sunscreen, and possibly a series of microneedling sessions. Lines that are visible at rest but still relatively shallow are ideal candidates for neurotoxin injections, which offer the most targeted and predictable results for bunny lines specifically. Deep, etched creases benefit from a combination of neurotoxin and filler, sometimes alongside a resurfacing treatment to improve overall skin texture.
Most people see the best long-term results by layering strategies: a retinoid and sunscreen as the daily foundation, with periodic in-office treatments to address what topicals can’t reach on their own.
