Objective
Dermatologists, aestheticians and Clarisonic Skin Care Brush users report improved absorption of serums and moisturizers following cleansing with the Clarisonic vs. other methods. In a clinical study, the absorption of an antioxidant commonly used in over-the-counter anti-aging products was evaluated following either manual cleansing or cleansing with the Clarisonic skin care brush.
Methods
Twenty Clarisonic users participated in the study. An aesthetician cleansed one-half of each subject’s forehead with the clarisonic and a cleanser for 20 seconds. cleanser remaining was gently removed by wicking with a moist cotton gauze. An equal amount of a 16% solution of Vitamin C (ascorbic acid) was applied to a defined location on each side of the forehead. After 20 minutes, ten skin sampling discs (D-Squame, CuDerm; Dallas TX) were used to sequentially collect corneocytes from the stratum corneum of each test site. Each disc was placed in an individual vial and sent to a laboratory for chemical analysis. The first two samples from each site represent product that was not absorbed. The remaining eight sets of samples for all 20 subjects were further analyzed for the amount and depth of absorption.
Results
Subjects demonstrated, on average, 30% greater absorption of ascorbic acid into the skin following cleansing with the Clarisonic compared to manual cleansing. Greater depth of penetration was noted after Clarisonic cleansing, with 61% more ascorbic acid present in the deepest 4 sets of samples collected from each side of the forehead.
Discussion
The clarisonic skin care brush has previously been shown to gently cleanse while maintaining skin hydration. These factors may contribute to the increased absorption of topical products observed following cleansing with the Clarisonic and documented in this study. Further research is needed to determine the exact mechanism of action for this documented increase. |
