Static wrinkles are caused by a loss of elasticity in the skin due to aging and environmental factors such as sun exposure or smoking. These types of wrinkles are best treated by dermal fillers.
Dynamic wrinkles are caused by repeated muscular contractions or facial expressions. In fact, some of these wrinkles, like worry lines, frown lines or laugh lines, are often named after facial expressions. When you’re young, your skin is more elastic and the lines easily bounce back to a normal, wrinkle-free look. But as you age, these lines become permanent fixtures on your face.
If the wrinkle is not caused by muscular contractions, a Botox for wrinkles treatment will not be effective and another treatment option should be considered.
