제안 방법
- The measurement is unitless, but is proportional to the dielectric constant of the surface layers of the skin, and increases as the skin becomes hydrated. The Nova DPM was used to take Sorption-Desorption measurements as described by Tagami, et aL〔이 Subjects held the left hand flat on a table and a baseline Nova DPM moisturization measurement was obtained. A 10-uI drop of water was placed onto the skin and spread so that it covered an area of approximately 1 cm in diameter.
- A 10-uI drop of water was placed onto the skin and spread so that it covered an area of approximately 1 cm in diameter. After ten seconds, the site was blotted dry, and Nova DPM measurements were repeated every 30 seconds for 3 minutes. The initial measurement immediately after water is removed from the skin is the water sorption property, or hydroscopicity of the skin.
- Subjects used their assigned dish detergent according to usage instructions for a period of nine weeks. The study lasted nine weeks with measurements taken initially and at 3, 6 and 9 weeks. The data reported here involves the initial and nine-week evaluations only.
- Mechanistically skin hydration can be improved with a moisturizer applied to the skin that draws moisture from the air, a humectant type moisturizer. In this test procedure, moisture was added to the skin surfece and absorption was measured via electrical low frequency, 30 Hz, impedance measurements, DPM units, of the stratum corneum. As might have been expected, neither test cell without moisturizer increased moisture absorption.
대상 데이터
- The data reported here involves the initial and nine-week evaluations only. One hundred four Japanese subjects completed the study that was run in the low humidity climates of Dallas, Texas and Colorado Springs, Colorado. Results were compared statistically using a paired t-test with changes from baseline being significant at the p<0.

- One hundred four Japanese subjects completed the study that was run in the low humidity climates of Dallas, Texas and Colorado Springs, Colorado. Results were compared statistically using a paired t-test with changes from baseline being significant at the p<0.05 level. Panelists reporting adverse events were terminated from the study and eliminated from the analysis.
