Neuromodulators only work on wrinkles that are caused by muscle movement. Hence these are called DYNAMIC wrinkles, and are typically called “expression lines”.
The most typical dynamic wrinkles are on the upper face, like frown lines, crow’s feet and forehead lines. The most typical cause is muscular hyperactivity, which is the excessive contraction of the muscles in question.
Deep-set wrinkles such as the “11” between the brows, horizontal lines on the forehead, and crow’s feet around the eyes are not removable by any form of topical solutions, despite advertising that always tries to persuade the public otherwise! These wrinkles are caused by smiling, frowning, squinting, and other facial expressions which have folded the skin over many years.
On the other hand, neuromodulators alone do not work on fine lines and wrinkles that are brought on by drooping or loss of plumpness in the face. These are known as fixed wrinkles or STATIC wrinkles and are often the lines we find on the cheeks, neck, and jowl areas. In such cases, neuromodulators need to be combined with other injectables like Hydration Fillers/Skin-boosters holistic improvements.
