Outcome Measures

Primary Outcomes (1)

  • Change in skin hydration

    * Measurement site: forehead, volar forearm * Measurement time points: 0, 1, 2, 3 months * Measurement site: cheek * Measurement time points: 0, 1, 2 months * Measurement device: Corneometer CM 825 * Parameter unit: AU (arbitrary unit) * Number of measurements at each time point: at least 5 * Outcome measure: Change from baseline * Method of analysis: * Mean, standard deviation and confidence intervals will be calculated. * Normality of the data distribution will be assessed. * Comparison between HA group and placebo group will be assessed using independent sample T-test or Mann-Whitney U test as a nonparametric alternative.

Secondary Outcomes (3)

  • Change in TEWL

    0, 1, 2, 3 months

  • Change in skin elasticity

    0, 1, 2, 3 months

  • Change in wrinkle depth

    0, 1, 2, 3 months
