A new study suggests that de-alcoholized muscadine wine could be a secret to healthier skin.
Women who consumed two glasses of this wine daily exhibited notable improvements in their skin’s elasticity and water retention, as compared to those drinking a placebo.
This research represents the first randomized clinical trial investigating the effects of non-alcoholic wine consumption on skin health.
Researchers attribute the positive outcomes to polyphenols, chemical compounds naturally occurring in many plants.
Unique Polyphenolic Profile
“Muscadine grapes have a unique polyphenolic profile compared to other red wine varieties,” said Lindsey Christman, Ph.D., a researcher at the University of Florida.
“Our study suggests that muscadine wine polyphenols have potential to improve skin conditions, specifically elasticity and transepidermal water loss, in middle-aged and older women.”
Muscadine grapes, indigenous to the Southeastern United States, are frequently used in winemaking.
Previous studies have indicated that polyphenols in muscadine wine, including anthocyanins, quercetin, and ellagic acid, could help reduce inflammation and oxidative stress.
Study Design and Findings
The study involved 17 women aged 40–67 who were randomly assigned to drink either de-alcoholized wine or a placebo beverage, which resembled the wine in taste and appearance but lacked polyphenols.
After six weeks, a three-week break was observed before the participants switched to the opposite beverage for six more weeks.
The researchers observed significant improvements in skin elasticity and a decrease in water loss at the skin’s surface, indicating a more effective barrier against damage.
However, no substantial difference was noted in the amount of skin wrinkles.
Skin smoothness improved, and inflammation and oxidative stress decreased, but no significant difference was found between the wine and placebo group regarding these factors.
Results and Future Research
“This cross-over study demonstrated that six weeks of dealcoholized muscadine wine consumption resulted in improvement of certain skin parameters associated with aging, such as elasticity on the forearm and barrier function of the skin on the face, when compared to baseline and placebo,” said Christman.
Although the study involved a small group of participants, future research with larger and more diverse groups would further confirm these findings.
Researchers also pointed out that commercially available muscadine wine, which contains alcohol, might produce different results. Therefore, the specific effects of polyphenols on skin health were the focus of this study.
