Bunny Lines Treatment in Singapore
Bunny lines are fine wrinkles that appear along the sides and bridge of the nose, particularly when you smile, laugh or scrunch your nose. They are a type of dynamic wrinkle, caused by repeated movement of the facial muscles around the nose.
Over time, repeated facial movement, together with changes in collagen and skin elasticity, can make these lines more noticeable and, in some individuals, visible even when the face is relaxed.

What Causes Bunny Lines?
Bunny lines are mainly associated with repeated contraction of the nasalis muscle and surrounding facial muscles. When these muscles contract, the overlying skin folds, producing the characteristic lines around the bridge and sides of the nose.
They may become more noticeable due to:
- Repeated facial expressions
- Natural facial muscle movement
- Age-related changes in collagen and skin elasticity
- Individual facial anatomy and muscle activity
Bunny lines are a normal type of facial wrinkle and do not require treatment unless their appearance is a concern.
Dynamic vs Static Bunny Lines

Dynamic Bunny Lines
Bunny lines that appear mainly when smiling, squinting or scrunching the nose are known as dynamic wrinkles. They form when the muscles around the nose contract and temporarily fold the overlying skin. When the face relaxes, these lines may initially disappear or become much less noticeable.
Static Bunny Lines
Over time, repeated facial movement combined with age-related changes in collagen, elastin and skin elasticity can cause these creases to become more established.
Eventually, some bunny lines may remain visible even when the facial muscles are relaxed. These are commonly referred to as static wrinkles.
Understanding whether bunny lines are primarily dynamic, static, or a combination of both is important because not every wrinkle should be treated in the same way. Dynamic lines are largely influenced by muscle activity, while established static lines may also involve changes in the skin itself. The appropriate treatment approach therefore depends on the individual's facial movement, skin condition and severity of the lines.
How Are Bunny Lines Treated?
Treatment for bunny lines depends on whether they are primarily dynamic lines caused by muscle movement or more established static lines that remain visible when the face is relaxed.
Wrinkle-Relaxing Injections for Bunny Lines
For dynamic bunny lines, wrinkle-relaxing injections may be used to temporarily reduce the activity of the muscles responsible for creating the creases around the nose. By relaxing these targeted muscles, repeated folding of the skin is reduced, helping to soften the appearance of bunny lines while maintaining natural facial expression.
Treatment requires careful assessment of the individual's facial anatomy, muscle activity and wrinkle pattern. Appropriate injection points and dosage are important, particularly around the nose where several muscles contribute to facial expression.
The effects are temporary and gradually wear off as muscle activity returns. Results vary between individuals but typically last for several months.
Treating Static Bunny Lines
When bunny lines remain visible even when the face is relaxed, muscle activity may no longer be the only contributing factor. Changes in collagen, skin elasticity and skin texture can also contribute to more established lines.
Depending on the condition of the skin, treatments that aim to improve skin quality, texture and collagen support may be considered alongside treatment of the underlying muscle activity.
What Other Areas Can Wrinkle-Relaxing Injections Treat?
In addition to bunny lines, wrinkle-relaxing injections may be used for selected facial lines caused by repeated muscle movement
Common treatment areas may include:
Frown lines between the eyebrows
Horizontal forehead lines
Bunny lines around the nose
Crow's feet around the outer corners of the eyes
Selected brow areas
Chin dimpling or wrinkles
The areas treated, injection points and dosage will vary according to the individual's facial anatomy, muscle activity and treatment goals.
