Effect of botulinum toxin pretreatment on laser resurfacing results: a prospective, randomized, blinded trial. Zimbler MS, Holds JB, Kokoska MS, et al. Arch Facial Plast Surg. 2001;3(3):165-169.
Background: Facial laser resurfacing and chemodenervation with botulinum toxin type A are used independently as means of nonsurgical facial rejuvenation. Recent reports in the literature have described combining these 2 therapies, claiming improved and longer-lasting laser resurfacing results. To date, no scientific investigation has been undertaken to prove or disprove this theory.
