Abstract

Background: A hydroquinone (HQ) skin care system has been designed for use in conjunction with nonsurgical procedures.Objective: The authors evaluate the efficacy of this system plus tretinoin for improving facial appearance in comparison to a standard skin care regimen in users of botulinum toxin Type A (BoNT-A).Methods: In this multicenter, randomized, investigator-masked, parallel-group study, 61 patients who received upper facial treatment with BoNT-A at a plastic surgery or dermatology clinic were randomly assigned to apply either the HQ system (cleanser, toner, proprietary 4% hydroquinone, exfoliant, and sunscreen) plus 0.05% tretinoin cream or a standard skin care regimen (cleanser, moisturizer, and sunscreen) for 120 days. Outcomes were assessed by the investigators and through a patient questionnaire.Results: Compared with standard skin care, the HQ system plus tretinoin resulted in significantly milder fine lines/wrinkles and hyperpigmentation at Days 30, 90, and 120 (p ≤.05) and significantly superior overall ratings for each of nine patient assessments at Days 90 and 120 (p ≤05). A relatively greater proportion of patients using the HQ system plus tretinoin believed that their study treatment had further enhanced the improvements attained with BoNT-A (86% vs 8%). Both regimens were generally well tolerated.Conclusions: Adjunctive use of the HQ system plus tretinoin can further enhance the improvements in facial appearance attained with BoNT-A. Applying the HQ system plus tretinoin offers multiple clinical benefits over standard skin care, including significantly greater improvements in fine lines/wrinkles and hyperpigmentation.
