What Are Bunny Lines?
Bunny lines are tiny wrinkles that tend to develop on the side of your nose, especially when you smile, laugh or squeeze your face. They are usually diagonal lines between nose bridge and top cheeks. They’re dynamic wrinkles, which means they develop during muscle contractions over the years. Bunny lines first show up when facial muscles are moving but can settle in as static wrinkles when the skin is less elastic.
Causes of Bunny Lines
There are several factors that play a role in the creation of bunny lines:
- Facial Movements: A common cause for bunny lines is the repeated contracting of the nasalis muscle that takes place during common facial expressions such as smiling and frowning. Constant movement gradually forms lines on the skin.
- Ageing: As you get older, your skin loses collagen and elastin, causing it to sag. This decreased elasticity is why lines that we make when we move our face can end up permanently engraved into the skin even when we’re not moving our face.
- Genetics: Hereditary factors may determine the speed and extent of wrinkle development. People with thin skin or robust facial muscles could find themselves getting bunny lines sooner.
- Skin Quality: Lifestyle and environmental factors like sunlight, smoking and dehydration, also play a role in the quality of skin on your lips and how soon fine lines appear.
Understanding Botox: Mechanism of Action
Botox is a neurotoxin made from botulinum toxin type A. It acts by temporarily paralyzing certain facial muscles, making it difficult for them to contract. For bunny lines, Botox is inserted into the nasalis muscle to avoid the creases of the skin when you make facial expressions. The end result is nicer skin that looks natural, without any distortion to the general activity of the face once the procedure is carried out correctly.
Types of Botox Used for Bunny Lines
There are several botulinum toxin brands suitable for treating bunny lines:
- Botox: The most common of brands, Botox is known for its predictability and accuracy. It has predictable results, and it has been well studied for cosmetic application.
- Bocouture: Bocouture is a botulinum toxin type A preparation with no complexing proteins. It is commonly used in those patients who lean in toward minimal additional proteins in the formulation to avoid resistance.
- Dysport: Dysport spreads a little more than Botox, and this is an advantage for larger areas. Although it is effective in those with more pronounced nasalis muscles, the dose must be adjusted accordingly in order to achieve the desired effect.
Applicability is determined according to personal requirements, degree of muscle tone and results sought, which will be discussed at your free consultation.

Bunny Lines Botox Treatment Explained
The Procedure Step-by-Step
The treatment process is quick and minimally invasive:
- Assessment: The lines are to be assessed between the nose. The muscle activity is measured and injection sites are determined.
- Preparation: The skin is cleaned well and a numbing cream is applied, if it is required for patient comfort.
- Injection: Tiny amounts of Botox are injected with a fine needle into the nasalis muscle on each side of the nose. How many injections are required depends upon the extent of the lines and the facial structure of the individual.
- Completion: The treatment takes 10 to 15 minutes generally, and has no downtime.
What to Expect: Treatment Timeline & Aftercare
You will begin seeing results within 3-5 days and the full effects will be apparent in about two weeks. Aftercare is straightforward:
- Do not rub or massage the treated area for 24 hours.
- Avoid heavy and energetic activities as well as intense heat on the treatment day.
- Do not lie down for 4 hours after the test.
Mild redness or swelling at injection sites usually subsides within a few hours.
Bunny Lines Botox Before and After: Real Results
Prior to treatment, bunny lines are noticeable when you speak and even at rest. The skin around the nose looks smoother and more relaxed following Botox, and fine creases are relatively blunted, without the conditioned reflex of a poker face. Natural results are usually obtained, there is no frozen look if injected properly.
Benefits of Bunny Lines Botox
- Immediate Visual Improvements
The most prominent benefit is the diminishment in lines bordering the sides of the nose. The skin appears smoother and the face looks rejuvenated. As the treatment is directed to a particular muscle the result is kept natural and the face aesthetic.
- Long-Term Skin Benefits and Maintenance Tips
Botox Bunny lines can become less severe with regular Botox injections over the long term. Keeping your skin healthy with hydration, sun-protection, and a skincare routine can also improve results. Botox can be a useful adjunct if used with other procedures; dermal fillers, for example, or skin boosters, and may enhance the overall appearance of the face.
FAQs About Bunny Lines and Botox
- How Long Does Bunny Line Botox Last?
Results usually last 3 to 4 months. Results may last depending on metabolism, muscle activity, and quantity of product used.
- How Many Units of Botox Are Used?
Bunny lines typically need 4 to 10 units, split between the left and right sides of the nose. The number will vary depending on the strength of your nasalis muscle and your level of wrinkle contractions.
- Will Bunny Lines Come Back After Botox?
Yes, Botox wears off and when muscles become more active again, the lines may return. Regular touch-up treatments may be necessary to maintain your results.
- Can Bunny Lines Appear because of Botox in Other Areas?
Sometimes yes! While treating other areas of the face like the forehead or crow’s feet, bunny lines can sometimes become more prominent. This is due to compensation by the nasalis muscle for diminished action of adjacent muscles.
- What Are the Side Effects?
We typically notice only temporary redness, minimal swelling, or a little bruising at the injection site. Occasionally you may experience some asymmetry or slight diffusion of the product, which can be corrected with follow up treatments.
- Is Bunny Lines Botox Suitable for Everyone?
The majority of healthy adults are eligible for this treatment. But it isn’t suitable for pregnant or nursing women or for anyone with specific neurological disorders. A complete consultation is necessary to determine candidacy.
