If you have noticed small diagonal creases on the sides of your nose every time you laugh, squint at the sun, or scrunch up your face, you are looking at bunny lines. They are harmless, but many people find that they become more visible over time and want to soften them without losing their natural expression.

At AgeEssence Medical Center in Playa del Carmen, Dr. Belinda Mayagoitia treats bunny lines with a conservative approach. This guide explains how the treatment works and what a safe, natural result looks like.

What Are Bunny Lines and Why Do They Appear?

Bunny lines are small, slanting wrinkles that form on the sides of the upper nose. They show up when you smile, laugh, or wrinkle your nose.

The Role of Muscle Movement:

The lines come from repeated contraction of the small muscles around the nose, mainly the nasalis. Every time those muscles pull, the skin folds in the same place. Over the years the folds can start to stay visible.

Skin Elasticity and Sun Exposure:

Skin loses elasticity with age, so the creases settle in more easily. In a sunny coastal city like Playa del Carmen, squinting and nose scrunching in bright light is also common. Daily sunscreen and sunglasses will not remove existing lines, but they help protect the skin.

What Does Botox Do for Bunny Lines?

Botox (botulinum toxin) temporarily relaxes the muscle that creates the fold. With less movement, the skin above it creases less, and the lines look softer.

Is Bunny Lines Botox Worth It?

It depends on what bothers you. Botox works best on dynamic lines, the ones that appear mainly when your nose moves. If the lines are visible even at rest, Botox can soften them, but it may not erase them, because skin quality also plays a part. Dr. Mayagoitia will tell you honestly at the consultation whether Botox alone is the right tool for your face.

How Many Units of Botox Are Used for Bunny Lines?

This area needs very little product. A common starting range is about 1 to 2 units per injection point. The total depends on your anatomy, muscle strength, previous treatments, and the result you want.

Why More Is Not Better Here:

The muscles of the nose sit close to the muscles that lift the upper lip and shape your smile. Extra product can spread to them. A small, measured dose is the safer choice, and it is easy to add more at a follow-up visit.

Where Is Botox Injected for Bunny Lines?

Injections go into a few small points on each side of the upper nose, over the muscle that causes the lines.

Bunny Lines Botox Injection Points:

The number and position of points are different for each person. Before treating you, Dr. Mayagoitia will ask you to smile and scrunch your nose so she can see exactly where your lines start and which muscle fibers are doing the work.

Bunny Lines Botox Depth:

The injection is shallow and placed into the muscle itself, not deep into the tissue below it. Keeping the product close to the target muscle, and using a tiny volume at each point, reduces the chance of it drifting toward the lip-lifting muscles. This is one of the main reasons the choice of injector matters so much in this area.

What Happens During the Appointment?

Consultation and Facial Assessment:

You will talk through your goals and any past treatments. Your facial movements are assessed at rest and in motion.

The Injection:

The skin is cleaned, and the product is placed with a very fine needle. Each injection takes a moment, and most people describe a brief pinch. The whole visit is short, and you can usually return to normal activities straight away.

Bunny Lines Botox Before and After:

Results build gradually.

• First few days: You may start to see less crinkling when you smile.
• Around 10 to 15 days: The full effect is in place.
• After that: Your lines look softer, your smile still moves naturally, and your nose does not look frozen.

A good result is subtle. People should notice that you look rested, not that you have had something done.

How Long Do Results Last?

Botox is temporary. Muscle activity returns gradually over a few months, and the lines slowly come back. Many people book a maintenance visit every three to four months, though your own timeline may differ.

Botox Bunny Lines Side Effects

Most side effects are mild and short-lived:

• Redness, swelling, tenderness, or bruising at the injection points
• A mild headache after treatment
• A tight or unusual feeling around the nose
• Slight asymmetry while the product settles

Bunny Lines Botox Gone Wrong: What Can Happen?

Problems are uncommon, and they are usually linked to placement or dose.

1. Spread to Neighboring Muscles:

If the product reaches the muscles that lift the upper lip, you may notice a temporary lopsided smile or difficulty raising the lip on one side.

2. Overtreatment:

Removing all movement around the nose can look stiff. Natural expression involves some movement, which is why we aim to soften the lines and not stop the muscle completely.

3. What If Something Feels Off?

Botox wears off on its own, and unwanted effects fade as muscle activity returns. It is important to know that, unlike hyaluronic acid filler, Botox cannot be dissolved. That is exactly why careful technique and a conservative dose matter more here than in almost any other area. If something feels wrong, contact the clinic and do not wait it out in silence.

Can Botox Make Bunny Lines Worse?

Botox does not cause bunny lines. However, when the forehead or the area around the eyes is relaxed, the nasalis can work harder to compensate, and existing lines may look stronger. If you already have Botox in other areas, mention it. Dr. Mayagoitia plans treatment by looking at the whole upper face, not one line at a time.

Who Is a Good Candidate?

Botox for bunny lines is a good fit if:

• Your lines appear mostly when you move your nose or smile
• You want a softer look without changing your expression
• You have noticed more nose scrunching after treating other areas

It is not suitable during pregnancy or breastfeeding, or if you have certain neuromuscular conditions. Tell us about all medical conditions, medications, and supplements at your consultation.

Aftercare Tips

• Do not rub or press the treated area for the rest of the day.
• Skip intense exercise and alcohol for about 24 hours.
• Avoid heavy facial treatments the same day.
• Report anything unexpected, such as pain that worsens or swelling that spreads.

Other Ways to Soften Bunny Lines

• Sun protection and skincare: Daily SPF, retinoids, and antioxidants improve skin quality but do not stop muscle movement.
• Skin-boosting treatments: Options such as microneedling or laser can help texture and fine static lines.
• Combination plans: For deeper lines, your doctor may suggest pairing Botox with a skin treatment.
