A new study, published in the Journal of the American Academy of Dermatology, evaluates whether the use of vitamins in skin care products can slow or reverse the effects of sun damage.

Based on a comprehensive review of the available published data on the role of vitamins in skin care products, a research team found that there is evidence to support the potential role of vitamins A, C, E and B3 in modifying the photoaging process.

However, they say that whether these vitamins are effective when used topically in skin products remains to be proven.

"While it’s evident that these vitamins can play a role in fighting sun damage, the question still remains whether these properties are effective when delivered in skin care products," said Dr. Jenny Kim.

Overall, researchers stress that maintaining a healthy lifestyle, eating a healthy diet and practicing sun protection is key to avoiding sun damage.

In addition, individuals are urged to get an adequate daily supply of vitamins to maintain a healthy lifestyle, since any insufficiencies may negatively impact the skin’s overall appearance.
