Retinol might be one of the most studied ingredients with hundreds of studies to its name, but Resveratrol has been hogging all the limelight of late. Researchers across the world have been researching with Resveratrol, not only because it has emerged as one of the best ingredients for the skin and a potential cure for cancer, but also because of the fact that it has a lot more to offer as well. This section tries to keep you posted about the latest research surrounding Resveratrol.
Resveratrol has been found to be a potent antioxidant and an effective free radical scavenger
A group of researchers working for the Otto-von-Guericke University conducted a study to examine the antioxidant benefits of Resveratrol. In this study, the authors investigated Resveratrol and Oxyresveratrol, and discovered that both ingredients offer the body with free radical scavenging capabilities and potent antioxidant properties. The researchers found that both Resveratrol and Oxyresveratrol managed to significantly diminish the nitrate levels in the body. Furthermore, the study also indicated that Oxyresveratrol showed a lower cytotoxicity when compared to Resveratrol.
Study finds that Resveratrol offers protective effects against UVA irradiated HaCaT cells
Researchers working for the Xiangya Hospital in China recently conducted a study in order to try and determine the photoprotective effects of Resveratrol on UVA irradiated HaCaT cells. In this study, researchers tested HaCaT cells under UVA irradiation with Resveratrol and divided the testing objects into a UVA irradiation group and a control group. The study showed that Resveratrol was successful in enhancing the proliferation activity of the HaCaT subjected to UVA irradiation. The experts also tested their results under an electron microscope. This test revealed that Resveratrol can also relieve the injury caused to the ultrastructure of HaCaT cells. Thus, it would be safe to say that Resveratrol possesses the powers to prevent oxidation caused by UVA irradiation and prevent cell proliferation of HaCaT cells.
Resveratrol might be helpful in preventing short-term UVB radiation damage
A group of researchers working for the University of Wisconsin conducted a study to examine the effects that Resveratrol had to offer in terms of protecting the skin from UVB damage. UVB damage is considered to be extremely dangerous because it leads to nonmelanoma skin cancer, the most common type of cancer among humans. During the course of the study, researchers discovered that a single application of Resveratrol actually managed to significantly inhibit the UVB damage caused in hairless mice. It was also observed that Resveratrol helped in inhibiting an increase in the level of lipid peroxidation, a common marker for oxidative stress. When both these observations are taken together, one can easily derive that Resveratrol might be offering substantial protection from the damage caused by the UVB rays of the sun.
Study finds that Resveratrol can prevent ethanol induced toxic effects
Researchers working for the University of South Carolina School of Medicine, USA tried to test potential agents that could protect the cerebellum from the toxic effects of ethanol in a study. Ethanol exposure during pregnancy can lead to a range of abnormalities in infants. These abnormalities are termed as FASD and therefore, it is imperative to prevent ethanol exposure during pregnancy. The study examined whether or not Resveratrrol could protect the cerebellar granule neurons from cell death induced by ethanol. After administering Resveratrol in postnatal day 7 rat pups, the researchers managed to prove that Resveratrol can actually prevent ethanol-induced apoptosis by increasing the chances survival of cerebellar granule cells and scavenging reactive oxygen species in the cerebellum’s external granule layer. Thus, the study helped to prove that Resveratrol offered neuroprotective effects to the cerebellum in a rodent model of FASD.
