Brief Summary:
Previous studies have shown that cranberry phytochemicals scavenge reactive carbonyls. Cranberry polyphenols have been reported to attenuate collagen degradation and inhibit oxidative stress in human cells. We hypothesize that cranberry juice consumption will attenuate skin photoaging and improve skin health in women via alleviate oxidative stress.

Detailed Description:
One of the causative factors of skin ageing is cumulative oxidative damages due to aerobic metabolism and UV irradiation. Cumulation of reactive oxygen species (ROS) causes collagen glycation and crosslinking which are direct causes of skin ageing. Previous studies have shown that cranberry phytochemicals scavenge reactive carbonyls. Cranberry polyphenols have been reported to attenuate collagen degradation and inhibit oxidative stress in human cells. It is unknown whether cranberry juice consumption could protect against UV -induced erythema and improve overall skin health. Furthermore, if it does have effect, what will be the mechanism? This human intervention study will be conducted to answer these questions. We hypothesize that cranberry juice consumption will attenuate skin photoaging and improve skin health in women via alleviate oxidative stress.

Primary Outcome Measures :
  1. Change from baseline Skin color change after UV irradiation at 28 days [ Time Frame: Baseline, 28 days ]
    Irradiation will be applied to dorsal skin (region not typically exposed to the sun) using an FDA approved UVB phototherapy light and a UV light meter. At each assessment, skin color will be measured before and 24 h after irradiation. Skin color will be evaluated by a colorimeter using the 3-dimensional color system with L-, a-, and b-values. L- and b- values assess lightness and browning effects, respectively. The a-value (red/green-axis) is a measure for reddening (erythema). The Δa-values (a-value 24 h after irradiation minus a-value before irradiation) will compared between baseline through 3 months; decreasing Δa-values indicates a photoprotective effect.

  2. Change from baseline Skin transepidermal water loss [ Time Frame: Baseline, 28 days ]
    Skin transepidermal water loss an will be measured using a Tewameter (CK Electronic GmbH, Germany). This is a handheld probes that allow for quick and easy measurements

  3. Change from baseline SELS parameters [ Time Frame: Baseline, 28 days ]
    SELS (Surface evaluation of the Living Skin) parameters, including smoothness, roughness, scaliness, and wrinkles, will be determined using a Visioscan VC20. This hand-hold device scans a 1 cm x 1 cm skin area (https://www.courage-khazaka.de/en/scientific-products/all-products/imaging/16-wissenschaftliche-produkte/alle-produkte/150-visioscan-e). Visioscan VC20 scanner consists of a camera, a high- resolution video sensor, and a UVA light no hazardous to human skin.

  4. Change in skin microbiome [ Time Frame: Baseline, 28 days ]
    For skin swabbing, a 4x4-cm square on a forearm will be swabbed with a cotton swab soaked in 0.9% sodium chloride with 0.1% Tween-20 in a Z-stroke manner.

  5. Change in baseline skin pH [ Time Frame: Baseline, 28 days ]
    Skin pH will be assessed using a skin pH meter (CK Electronic GmbH, Germany). This is a handheld probes that allow for quick and easy measurements.

  6. Change from baseline hydration [ Time Frame: Baseline, 28 days ]
    Skin hydration will be measured with a Corneometer (CK Electronic GmbH, Germany. This is a handheld probe that allows for quick and easy measurements.

  7. Change in Skin erythema and melanin index [ Time Frame: Baseline, 28 days ]
    Skin erythema and melanin index will be assessed with a Mexameter, (CK Electronic GmbH, Germany). Each of these are handheld probes that allow for quick and easy measurements

  8. Change in skin lipidome [ Time Frame: baseline, 28 days ]
    Stratum corneum layer on forearm skin will be sampled with 16 D-squame® tapes using a standard noninvasive tape stripping technique. This will be sent for lipidomic analysis


Secondary Outcome Measures :
  1. Survival rate of human keratinocyte under UV light [ Time Frame: 24 hours ]
    The immortalized human keratinocyte cell line (HaCaT) will be cultured in Dulbecco's Modified Eagle Medium. Cells will be incubated with human serum collected after 2-hour and 4-hour cranberry juice intake or water intake for 24 hours.
