Since researchers have found that two glasses of wine a day can keep skin sagging at bay, you might be ready to stock up on a few bottles.
But there’s a catch: It’s not the alcohol content in wine that has been shown to benefit your complexion.
Alcohol can have a drying effect on your skin every time you drink it, according to a charity drink consciousThis makes it “wrinkled, dull and gray or bloated and swollen” and prone to conditions like eczema, psoriasis and rosacea.
The team behind the new research – presented at the annual meeting of the American Society for Nutrition – in gave the participants dealcoholized wine from which most or all of the alcohol content had been removed.
They found that women who drank two glasses of non-alcoholic Muscadine wine daily showed significant improvements in their skin’s elasticity and water retention.
Researchers suspected that the anti-aging effect on women’s skin could be due to chemical compounds in wine called polyphenols that occur naturally in many plants.
“Muscadine grapes were found to have a unique polyphenol profile compared to other red wine varieties,” said Lindsey Christman, PhD, who conducted the research along with Liwei Gu, PhD, professor of food chemistry and functional foods at the University of Florida.
“Our study suggests that muscadine vine polyphenols have the potential to improve skin condition, particularly elasticity and transepidermal water loss, in middle-aged and older women.”
Muscadine grapes are native to the southeastern United States and are commonly used in winemaking. Previous research has shown that polyphenols may help reduce inflammation and oxidative stress.

dr Christman explained, “We used dealcoholized muscadine wine because we were interested in the effect of the bioactive compounds in wine, particularly the polyphenols, on skin health.”
For the study, the researchers asked 17 women, ages 40 to 67, to drink 10 ounces — about two wine glasses — of dealcoholized wine or a placebo drink that didn’t contain polyphenols every day for six weeks.
They took a three-week break and then switched the women to the other drink for another six weeks.
They examined the women’s skin at the beginning and end of the six-week period for signs of inflammation and oxidative stress and found that drinking muscadine wine significantly improved skin elasticity.
A loss of elasticity causes the skin to become more saggy with age.
The muscadine wine also appeared to reduce water loss from the skin’s surface, a value that suggests the skin provides a more effective barrier against damage.
However, the researchers observed no significant difference in the amount of wrinkles on the skin between participants who drank wine or placebo.
“This cross-over study showed that six-week consumption of dealcoholized muscadine wine resulted in improvements in certain age-related skin parameters, such as forearm elasticity and facial skin barrier function, compared to baseline and placebo,” said Dr. Christian.
“This is likely due to the reduction in inflammation and oxidative stress.”
She pointed out that the results of the study would likely be different if the participants had drunk wine with alcohol.
She also acknowledged that repeating the study with a larger and more diverse group of people could help confirm the results, as only 17 women participated.
