Bunny lines, such a cute name, but what are they?!

Bunny lines, such a cute name, right? But what are they?

Bunny lines refer to facial wrinkles that manifest on the sides of the nose, particularly noticeable during expressions such as smiling, laughing, or scrunching the nose – resembling the facial movements of a rabbit, hence the name 'bunny lines.' These lines develop due to the repetitive contraction of the (upper) nasalis muscle on the lateral nose with some contribution from the levator labii superioris alaeque nasi muscles.

While some find these lines adorable and cute, others are bothered by them. Fortunately, effective treatment exists for those who want to get rid of these lines.


The mainstay of treatment for bunny lines is botulinum toxin, such as Botox or Xeomin. Thorough clinical assessment should be performed by an experienced doctor as many facial muscles are involved in our glabella and nasal regions to ensure the correct diagnosis is made and the treatment is deemed appropriate.

Precise administration of botulinum toxin, targeting the responsible muscles for bunny line formation is performed in clinics, usually without the need for any anaesthesia. Exact dosage is determined based on the individual's facial structure and the extent of the lines.

Results are generally noticeable within 5 to 12 days post-treatment, depending on the specific dosage used and individual's clinical situation.


1. How long do they last? Bunny line treatment results typically last 3 to 6 months, with variations based on factors like skin type and muscle activity.

2. Is the treatment risky?

Botulinum toxin injection for facial wrinkles / lines is considered safe, with minor risks such as bruising, which usually resolves within days.

3. Can I combine bunny lines treatment with other treatments?

Bunny line treatment is frequently combined with other facial treatments for a comprehensive rejuvenation approach, e.g. botulinum toxin to other parts of the face, fillers, or energy-based machines.

4. When can I return to normal activities?

Minimal downtime is involved, with most patients resuming normal activities immediately after the procedure.

5. How do I know if I am suitable?

The treatment is generally suitable for most individuals, but a thorough consultation is crucial to assess suitability based on skin condition and health and also to fully inform individuals on risks and expected outcome.

6. Will I look natural afterwards?

Unlike forehead and crowfeet lines, even with near complete elimination of bunny lines one can still have very natural and authentic facial expressions.

7. Does it have a preventative effect?

While primarily addressing existing lines, the treatment may have a preventative effect on further development of linese by relaxing the nasalis muscle.

Individuals considering the procedure should schedule a consultation with an experienced plastic surgeon or dermatologist to discuss their goals and the potential outcomes they can anticipate.
