Adjuvant Oral Zinc and Botulinum Toxin, Adjuvant Zinc May Increase the Efficacy of Botulinum Toxin, Botulinum Toxin, Cosmetic, Glabellar Frown Lines, Zinc Supplementation for Botulinum Toxin Treatment of the Forehead
Conditions
Brief summary
The current literature suggests that zinc supplementation may increase the duration of botulinum toxin; however, each study had their limitations. Further, no one has studied the effect of zinc supplementation for botulinum toxin treatment of the forehead. The purpose of this study is to evaluate the effect of zinc supplementation on frontalis muscle denervation by objectively assessing the degree of forehead rhytids and movement of the eyebrows.
Interventions
