Neurotoxins: Evidence for Prevention.

<p>Onabotulinum Toxin A is the gold standard treatment for temporary dynamic rhytid reduction. Clinicians have observed a long-term and preventive benefit for patients beyond muscle relaxation particularly in patients who receive repeated treatments over time. These changes include progressive reduction of rhytides, prevention of dynamic rhytides, and improvements in skin quality. In this brief paper, we review basic science, clinical, and anecdotal evidence that explores a long-term and potential preventive effect of Onabotulinum Toxin A injections.</p> <p><em>J Drugs Dermatol. 2017;16(6 Suppl):s87-90.</em></p>.
