Younger patients often seek Botox treatments as a preventative measure to keep skin smooth and voluminous before the onset of facial wrinkles and lines. Preventative Botox can keep wrinkles from forming in the first place, rather than attempting to fix them after they have developed. By slowing down the use of the muscles, preventative Botox can prevent fine lines and wrinkles, including some lines that are harder to treat once they form, such as the marionette lines.
