Richard Clark received FDA approval
Richard Clark, a plastic surgeon from Sacramento (CA), was the first to document a cosmetic use for botulinum toxin.
Clark realized that botulinum toxin (Botox® injections), which had been previously used only for cross eyed babies and facial tics, could also be injected to smooth the wrinkles of the right forehead to match her paralyzed left. He received FDA approval for this cosmetic application of the toxin and successfully treated the person and published the case study in 1989.
