Bunny lines

Bun­ny lines are fine, dia­go­nal wrink­les on the sides of the upper nasal bridge. They owe their name to the way rab­bits wrink­le their noses.

Cau­ses

They are cau­sed by a small mus­cle on the nose that con­tracts when laug­hing, scrun­ching the nose or squin­ting. Some peo­p­le natu­ral­ly use this mus­cle more than others. Bun­ny lines can also beco­me more noti­ceable after the fore­head and frown line have been trea­ted with botu­li­num toxin, as facial expres­si­on shifts to neigh­bou­ring muscles.

Sym­ptoms

The lines are main­ly visi­ble during move­ment and may extend towards the inner cor­ners of the eyes. Over time they can also show at rest.

Tre­at­ment

The usu­al tre­at­ment is a very small amount of botu­li­num toxin pla­ced pre­cis­e­ly into the nasal mus­cle. The effect appears after a few days and typi­cal­ly lasts three to four months. It is often com­bi­ned with tre­at­ment of the frown line and cro­w’s feet to keep expres­si­ons balan­ced. Too high a dose can affect the upper lip.
