abstract: ten women, between the ages of l8 and 65, with moderate hyperpigmentation (demonstrating striking uneven pigmentation when screened with ultraviolet light) were selected to participate in the study. The subjects were given sample "a" and "b" which were randomly assigned to the left or right side of the face. Panelists were instructed to apply the products twice a day (morning and evening) to the facial area for 8 weeks. Expert grader evaluations for fine lines/wrinkles, reduction in pigmentation, irritation potential, and overall improvements of the skin were made at baseline and at 4 and 8 weeks after product use. Standard 35 mm and ultraviolet photographs were also taken, standardizing distance and positioning of the subjects, pre and post product application.
Data generated for Radiance Revealing Complex verses prescription hydroquinone indicated no differences in irritation potential or reduction in fine lines and wrinkles. Conversely, a 13% difference between the products was noted for general skin lightening and overall improvement (Radiance Revealing Complex being directionally better).
results: In conclusion, the data generated for the products tested implies that Radiance Revealing Complex is directionally better than prescription strength hydroquinone.
