Clarisonic sonic cleansing works so well that products absorb better

Methodology:

• 20 subjects participated in the study
• One side of the forehead was cleansed with Clarisonic sonic cleansing, the other cleansed manually
• Equal volumes of Vitamin C (aq) were applied to both sides of the forehead
• After 20 minutes, 10 consecutive skin tape strips on each treatment site were applied and removed
• Spectrometric chemical analysis was used to quantify the amount of Vitamin C on each tape strip indicating absorption into the skin at various depths

Results:

• Up to 61% greater absorption of Vitamin C after using Clarisonic sonic cleansing compared to manual cleansing
• Tape lifts were used to quantify the amount of Vitamin C absorbed into the skin, comparing Clarisonic sonic cleansing with manual cleansing
