Can Botox be used to prevent marionette lines?

Botox excels at treating crow's feet, glabellar and forehead lines. It does not address skin volume issues and facial folds due to cheek migration during facial aging. Facial fillers like Voluma can address this issue.

No, I don't recommend Botox for this, but filler can be used to improve marionette lines. It takes 1-2 weeks for final results. Hope this helps.
