What is bunny lines Botox

Bunny lines Botox treats the fine diagonal lines that appear on either side of the nose when smiling, laughing, or scrunching the face. These characteristically oblique wrinkles are caused by repeated contraction of the nasalis muscle and can appear even in younger patients. Botulinum toxin type A gently relaxes the muscle at these precise points, softening the lines without compromising natural facial expression. It is a discreet and targeted approach in aesthetic medicine in Lisbon.

Who is it for

Suitable for anyone who notices visible diagonal lines on the sides of the nose when smiling, as well as for patients who have had glabellar Botox and find that bunny lines have become more prominent as a result, a well-documented compensatory muscle pattern. Not recommended during pregnancy, breastfeeding, in neuromuscular disorders, or with active infection in the nasal area.

What to expect from the session

The consultation begins with an assessment of nasal muscle dynamics during smiling and speaking. The toxin is applied with a microneedle at 1 to 2 points on each side of the nose. The session is quick, 10 to 15 minutes, no anaesthesia required, and you can leave with no visible signs of treatment.

Results timeline

Early softening becomes visible between day 3 and day 5. Full results stabilise between days 10 and 14, with bunny lines clearly reduced when smiling. Average duration is 3 to 4 months, varying according to individual muscle strength and how quickly your body metabolises the toxin.

Aftercare

For the first 4 hours, avoid lying down or bending the head forward. During the first 24 hours, skip intense physical exercise, saunas, and hot baths. Throughout the first week, avoid massaging the treated area, postpone aggressive facial treatments, and use sunscreen whenever you are exposed to the sun.
