A recent study suggests that using a new 4% hydroquinone skin care system—one specifically designed for use in conjunction with nonsurgical cosmetic skin treatments—in combination with tretinoin (Retin-A) further enhances the improvements in skin appearance attained using botulinum toxin type A.

Applying the hydroquinone system plus tretinoin may offer multiple clinical benefits over standard skin care, including significantly milder fine lines/wrinkles and hyperpigmentation. The results of the study, “Further Enhancement of Facial Appearance with a Hydroquinone Skin Care System Plus Tretinoin in Patients Previously Treated With Botulinum Toxin Type A,” appear in the July issue of the Aesthetic Surgery Journal.

In this multicenter, randomized, investigator-masked, parallel-group study, 61 patients who received upper facial treatment with botulinum toxin type A at a plastic surgery or dermatology clinic were randomly assigned to use either the hydroquinone 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.
