Pomegranate and vitamin D protect the skin
- Pomegranate reduced facial wrinkles
Diet and lifestyle measures may help protect the skin. In this study, 28 healthy men and women, aged 25 to 55, took a placebo or 250 mg of pomegranate extract per day. Before and after four weeks, doctors measured facial wrinkle severity, and changes in the skin and gut microbiomes.
Those taking pomegranate saw a 6.2 percent decrease in facial wrinkle severity compared to a 1 percent increase for placebo, and also had 21.9 less oily sebum excretions on the forehead compared to a 17.2 increase for placebo. The skin microbiome also contained higher levels of good bacteria.
Beneficial short-chain fatty acids in the gut increased 38 percent for pomegranate vs. a 1.8 percent decrease for placebo. And those in the pomegranate group with higher levels of the gut bacteria, eggerthellaceae, had less trans-epidermal water loss—meaning more hydrated skin.

- Vitamin D supplements linked to less skin cancer
Because earlier studies have been inconclusive, doctors were not sure of the role vitamin D plays in cancers of the skin. This study included 498 men and women, aged 21 to 79, 96 of whom were immunosuppressed, increasing their chances for skin cancers. Doctors measured vitamin D levels and compared them with past or present melanomas, and any type of skin cancer.
Overall, those who regularly supplemented with vitamin D were less than half as likely as those who did not take vitamin D supplements to have, or to have had, a melanoma, and less likely to have, or to have had, any type of skin cancer.
