NCT04614753

Brief Summary

The objective of this clinical trial is to determine the activity of dealcoholized muscadine wine to alleviate oxidative stress, inflammation, skin photoaging, and alter gut microbiome in women 40-67 years of age. The investigators hypothesize that dealcoholized muscadine wine daily for 42 days will significantly alleviate oxidative stress, inflammation, skin photoaging, and alter the gut microbiome in women compared to drinking sugar water.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity of skin to UV radiation

    Irradiation will be applied to dorsal skin (back, scapular region not typically exposed to the sun) with 2 times of minimal erythema dose using an FDA approved UVB phototherapy light and a UV light meter. At each time point on day 0 and 29, skin color will be measured before and 24 h after irradiation. Skin color will be evaluated by a colorimeter.

    Baseline, 28 days

Secondary Outcomes (7)

  • skin transepidermal water loss

    Baseline, 28 days

  • Change in Gut Microbiome

    Baseline, 28 days

  • skin hydration

    Baseline, 28 days

  • skin erythema and melanin index

  • skin pH
