Have you ever noticed the small wrinkles that appear on the sides of your nose when you smile or laugh?

These delicate lines are often called bunny lines, and while they are completely natural, some women begin to notice them more as time goes on.

Many people admire how certain actresses maintain very smooth skin around the nose when they smile. While we can never assume what treatments someone may or may not have had, subtle treatments like  Botox are often discussed in aesthetic medicine when talking about refined, natural-looking results.

In this guide, I will explain what bunny lines are, why they appear, and how bunny lines Botox can soften them while preserving your natural expression.

What are bunny lines? 

Bunny lines are the small wrinkles that appear on the sides of the nose when you smile, laugh, or scrunch your nose.

They are caused by repeated contraction of the nasalis muscle, which is responsible for facial expressions around the nose.

For many women, bunny lines begin as faint lines that only appear when the face moves. Over time, repeated movement can make them more visible.

While these lines are a normal part of facial expression, some people prefer a smoother appearance in this area.

Are bunny lines normal?

Yes. Bunny lines are a natural part of facial expression and appear when the muscles around the nose contract.

Why do bunny lines appear?

Bunny lines appear mainly because of repeated facial movement.

Every time you smile, laugh, or wrinkle your nose, the muscles in that area contract. Over time, this repeated motion can create small wrinkles in the skin.

In some cases, bunny lines may become more noticeable if other facial muscles are relaxed with treatments like Botox in the forehead or frown lines. The body may compensate by increasing movement in nearby muscles.



This is why experienced providers always consider overall facial balance when planning aesthetic treatments.

What is bunny lines Botox?

Bunny lines Botox is a treatment where a small amount of Botox is injected into the nasalis muscle on the sides of the nose.

The goal is not to eliminate facial expression. Instead, the treatment gently relaxes the muscle responsible for creating these wrinkles.

When the muscle relaxes, the skin around the nose appears smoother when you smile or laugh.

Because this is a small facial area, the treatment usually requires only a few units of Botox.

What do bunny lines Botox results look like?

The results of bunny lines Botox are subtle.

You will still be able to smile, laugh, and express yourself naturally. The difference is that the wrinkles that appear along the sides of the nose become softer and less noticeable.

Many patients choose this treatment because it creates a refined and balanced appearance without dramatic change.

The goal is always to maintain natural expression while improving skin smoothness.

How long does bunny lines Botox last?

Like most Botox treatments, bunny lines Botox typically lasts three to four months.



Over time, muscle activity gradually returns and the wrinkles may reappear when making expressions.

Many patients choose to repeat the treatment a few times per year to maintain smoother skin in this area.

Is bunny lines Botox safe?

Botox has been used safely in medical treatments for decades when administered by trained professionals.

Because bunny lines treatments involve small doses of Botox, the procedure is quick and minimally invasive.

Safety depends on proper injection placement and appropriate dosing, which is why it is important to work with an experienced medical provider.

What to expect during the treatment

The treatment itself is very quick.

During your appointment, your provider will evaluate how the muscles around your nose move when you smile or scrunch your nose.

Small injections are then placed into the nasalis muscle.

The entire process usually takes only a few minutes, and most patients return to their normal activities right away.

When will you see results?

Results from bunny lines Botox usually begin to appear within three to five days.

Full results are typically visible after one to two weeks.

The change is subtle but noticeable. Many patients simply feel that their smile looks smoother and more balanced.

How many units of Botox are used for bunny lines?

Most treatments use a small number of units, typically between four and eight units, depending on muscle strength.

Can bunny lines Botox be combined with other treatments?

Yes. It is often combined with treatments for the forehead, masseter muscle, frown lines, or crow’s feet to create balanced facial results.
