Title: A Split-Face Evaluation to Assess the Efficacy of a Hydrolyzed Roe Cream in Reduction of Erythema Following Chemical Peel.

The PRO Rebalancing Lotion was applied to one side of the face of 30 healthy female subjects (average age=54.9 years, range 33-65 years) immediately following 4 to 15 minutes peel treatment. The opposite side remained untreated. Visia-CR digital photographs were taken at baseline and 8 and 24 hours post-facial peel. Objective dermal irritation assessments were done by a blinded investigator, graded on severity of facial erythema and edema on a 5-point scale; 0=none, 1=slight, 2=mild, 3=moderate, 4=severe. Subjects completed a perception questionnaire.

Reduction in erythema was greater (P less than or equal to: 0.05) for the treated side of the face compared to the untreated side at both 8 and 24 hours post-peel. Both sides showed reduction in erythema compared to immediate post-peel. No edema was observed. At eight hours, more than 50% of subjects agreed on the five attributes, and at 24 hours, 57% (17/30) of subjects agreed. At eight hours, greater than or equal to 80 percent of subjects strongly agreed or agreed that the treated skin feels hydrated and moisturized immediately after application. At 24 hours, more than 90 percent of subjects strongly agreed or agreed that treated skin feels perfectly hydrated and moisturized. When asked about their overall impression of the product, 60 percent (18 subjects) of subjects responded said, “I love it.” All subjects completed the study. No adverse events were reported.
