Primary outcomes

  1. skin moisture

    Time frame: subjects drank 50 ml every night for 28 days

    using corneometer CM825 to examine skin moisture (The higher the value, the more water content, C.U., corneometer units )

  2. skin elasticity

    Time frame: subjects drank 50 ml every night for 28 days

    using cutometer dual MPA580 to examine skin elasticity (The closer the R2 value is to 1, the better the elasticity and no unit)
