Authors Katarina Kesty, MD, MBA and David J. Goldberg, MD, JD, investigated the optimal number of units and longevity of abobotulinumtoxinA for the treatment of oily skin through a randomized, double-blind, placebo-controlled study. They published their findings in the Journal of Dermatologic Surgery.
The study included 50 subjects that got either 0, 15, 30 or 45 units of abobotulinumtoxinA injected into their foreheads. Six months after the treatment, subjects were evaluated for the effectiveness of the treatment in decreasing the oiliness of their skin and the duration of this effect.
The subjects who received 30 or 45 units of neurotoxin experienced a significant reduction in oily skin. There were no treatment-related adverse events reported during the study, and both the subjects and investigators reported a high level of satisfaction with the treatment. They concluded that the use of 30 or 45 units of abobotulinumtoxinA are safe and effective doses in treating oily skin for improved cosmetic appearance. Read the full study here.
