Botulinum toxin
ListedCan soften selected movement-related lines temporarily; dosing and placement require a qualified clinician.
Expression lines that become more visible when facial muscles move. Lines visible when the face is at rest.


The same eight facts on every condition comparison.

Dynamic Wrinkles Fine lines fan outward from the outer corner of the eye during a smile.

Static Wrinkles Creases remain visible at the outer corner while the eye is open.
Repeated facial muscle movement folds the overlying skin. These lines become more visible during expressions such as smiling or frowning.
Aging, ultraviolet exposure and repeated folding change collagen and elastic support. The resulting creases remain visible even when the facial muscles are relaxed.
Dynamic Wrinkles. Usually becomes more noticeable during adult ageing; facial anatomy creates wide variation.
Static Wrinkles. Usually becomes more noticeable during adult ageing; facial anatomy creates wide variation.
Repeated muscle movement folds overlying skin.
Ageing, ultraviolet exposure and repeated folding change collagen and elasticity.
Evidence labels come from each condition’s own treatment list.
Cosmetic options depend on the depth of the lines, skin type and goals. A clinician may consider resurfacing or other procedures after discussing likely improvement, pigment risk and recovery.

Expression lines move with the underlying muscles and may become visible at rest over time. Cosmetic treatment is optional, and the effects of treatments such as botulinum toxin are temporary.
Lines visible at rest tend to persist and may deepen over time. Sun protection helps limit further damage; cosmetic procedures can improve appearance but do not stop aging.
These are usually cosmetic structural changes rather than signs of disease.

Seek medical assessment for sudden, painful or one-sided change rather than assuming it is ageing.

Use sunscreen, gentle moisturizer and avoid smoking. Choose procedures only after an individual assessment.
