As we age, everyone develops fine lines on their face—at first very subtle, but becoming more noticeable over time. These include “bunny lines,” affectionately known as “bunny wrinkles,” which run from the bridge of the nose toward the corners of the eyes. Here you’ll learn why they form and how you can have them treated easily.
The nose wrinkles with the funny name Bunny Lines remind of the facial expressions of a cute, sniffing or munching bunny. They are created by your individual facial expressions, for example when you snort or laugh. Not everyone is affected by them, but if you like to laugh often, Bunny Lines might show up in you too. In the beginning, the wrinkles are still very discreet and only show up with the appropriate facial expressions. This can look really cute. However, since if you like to laugh, you probably laugh more often, noticeable wrinkles will gradually develop from the fine lines that run from the root of your nose to both corners of your eyes. Also, do you have dry skin or enjoy extensive sunbathing? Both additionally support the development of the bunny-like nose wrinkles.
In young people, the wrinkles are often considered charming when laughing or nasally, especially since they appear when laughing and laughter radiates cheerfulness. These cute nose wrinkles belong to you and distinguish you like your very own character. However, as you age, your skin loses more and more elasticity and cell regeneration slows down. The once fine lines on the bridge of the nose become longer and stand out more clearly: from the root of the nose to the corners of the eyes, they can reach several centimeters in length, and from a certain depth of wrinkles, they remain more and more evident when the face is at rest. What looked charming in your younger years with an otherwise fresh, smooth complexion looks old as the years go by – until your face is eventually marked by deeper wrinkles.
On tanned skin, they often remain visible as lighter stripes. Nose wrinkles become a problem at the latest when they bother you and you no longer feel comfortable when you look in the mirror.
You have individual facial expressions. Facial expressions cause certain facial muscles to be used more frequently: Your facial expressions belong to you, and when you like to laugh in your charming way or wrinkle your nose, the very facial muscles in the area where the bunny-like wrinkles form become active. They form because the muscles activated there make your skin contract in a certain way over and over again. These are the initial fine lines you see. As soon as the muscles are no longer active, the young elastic skin returns to its original state. With the aging of the skin, this happens less and less, and even with relaxed facial muscles, expression lines remain: first very slight, later more and more pronounced, until at some point deeper furrows are visible. The process is the same as for forehead wrinkles.
At first, you may not even notice the fine lines on the bridge of your nose. But it’s easy to find out if you’re developing bunny lines in front of the mirror: look closely when you wrinkle your nose or laugh. While doing this, you can see if there are any small wrinkles running outward at the root of the nose. Is that the case? Then you can expect them to become more prominent and also longer as the years go by.
Since dry skin and sun exposure promote bunny lines, you can also take a look in the mirror if your skin feels particularly dry or after being exposed to regular UV rays. Then try wrinkling your nose: can you see fine wrinkles starting from the root of the nose? Try the same thing when you smile at your reflection.
Nose wrinkles should be treated at the latest when you find them disturbing. However, keep in mind that the sooner you do something about it, the more effective the result will be. This is because it is simply easier to reduce less pronounced wrinkles than those that have already burrowed deep into the skin when the facial muscles are at rest.
Also keep in mind that if wrinkles in other areas of the face are smoothed out with hyaluronic acid or Botox, it may increase wrinkles at the root of the nose. There are two reasons for this:
Bunny lines can be smoothed out in just a few minutes without surgery. Because these wrinkles are caused by muscle movement, the most effective approach is to target the muscle responsible directly.
A Botox treatment relaxes the nasal muscle that causes smile lines with just a few, very precisely placed injections. The lines smooth out, while your smile and facial expressions remain completely intact, because only a small, precisely defined area of muscle is treated. The treatment takes about ten minutes; you’ll see the first results after a few days, with the full effect visible after about two weeks, and the results last an average of 4 months.
As described above, bunny lines can become more pronounced if the eye muscle has been smoothed in another area, such as the crow’s feet, causing the untreated muscles to work harder as a result. That’s why we most often treat bunny lines as a supplement to another Botox treatment or hyaluronic acid injection. This isn’t just medically sensible—it’s also more affordable: As an additional treatment area, bunny lines cost only €90 instead of €140.
When it comes to bunny lines, skincare is actually more effective than for many other types of wrinkles. Dry skin and sun exposure noticeably accelerate their formation, so a good moisturizer and consistent sun protection really do help slow down the appearance of these fine lines. There’s just one thing they can’t do: smooth out a wrinkle that has already set in. That requires treatment targeting the muscle.
