TEWL measures of areas after twice-daily treatment with Light Formulation, vehicle, and vehicle plus as well as an untreated control area. Values are mean differences between the respective Week 1 and Week 2 recordings and baseline levels. Significance was set at P<0.05. a=significantly lower than untreated control (improvement); b=significantly lower than vehicle and vehicle plus; c=significantly lower than vehicle; d=significantly higher than untreated control (worsening) (P<0.05)
