Bunny Lines
Bunny lines are the small diagonal wrinkles that fan out across the sides of the nose. Like other expression lines, they appear when you scrunch your nose, smile widely or laugh, and ease when your face relaxes.
Usually subtle, sometimes more noticeable
For most people bunny lines stay light and only show with movement. They can become more defined in those with strong, frequent expressions, or alongside other changes around the eyes and nose. Knowing what drives them helps you decide whether they are worth addressing at all.
Why do bunny lines appear?
Bunny lines come mainly from the nasalis, the small muscle that scrunches the nose during expression. Every scrunch folds the thin skin along the sides of the bridge. As with all expression lines, the question is how well your skin recovers from that folding, and that depends largely on its collagen and elastin reserves.
Repeated nose movement
Scrunching the nose when you smile, laugh or react to a bright light folds the skin diagonally across the same spots. Repeated often enough, this continuous motion encourages fine lines to form and, in time, to remain faintly visible at rest.
Collagen and elastin decline
Collagen gives skin its firmness and elastin its bounce; both are made by fibroblasts in the dermis. The skin over the sides of the nose is about 2 mm thick and crinkles each time you scrunch or laugh. As we age, fibroblast output drops and elastin stops renewing, so this skin recoils less. The diagonal bunny lines that once vanished now linger.
Sun exposure
Ultraviolet rays, and UVA in particular, reach deep into the skin and break down collagen and elastin faster than the body can rebuild them, a process called photoaging. By some estimates it drives up to 80% of visible skin aging. Bright light also makes you squint and scrunch, adding movement to skin that is already losing resilience. The weaker the support along the nose, the more readily the line deepens.
Oxidative stress and lifestyle
Daily habits pile on. Smoking, alcohol, pollution and too little sleep generate oxidative stress, an excess of unstable molecules called free radicals that corrode collagen and elastin. A sugar-rich diet adds glycation, where sugar stiffens these fibres. Both speed how fast lines along the nose form and set.
