In a four-week study 19 male and female panelists applied RENU Advanced Ultra Replenishing Moisturizer once per day to the face and neck. Skin moisture measurements were taken by a Corneometer® at the beginning and at the conclusion of the study. A Corneometer is the most used method to reproducibly and accurately determine the hydration level of the skin surface. The accuracy of other hydration measurement instrumentation is typically assessed against the standard of the Corneometer. In the clinical-dermatological application test, researchers screened and subjected participants to an initial dermatological examination before the clinical trial commenced. Individuals who show no signs of pathological changes in the skin are selected for the testing. Participants are instructed not to use any other similar formulations on the test site. Following the application period, the participants undergo another dermatological examination to ascertain whether the trial product has caused any irritation to the skin.
Corneometer analysis measured an increase in skin moisture by 43% over four weeks.
