For years there has been research conducted on the health benefits of soy. Along with being a good source of antioxidants and protein, soy can also be beneficial to the skin.
According the the Mayo Clinic, soy may improve the signs of sun damage to the skin. This includes discoloration, blotchiness and texture. Though more research needs to be conducted, there has also been preliminary evidence that shows that soy may help with skin aging by possibly reducing wrinkles.
The National Institutes of Health reports that a study conducted on hairless mice found that treating the rodents' skin with soy resulted in the skin having a better overall appearance and less wrinkles.
The study states in the conclusion, "it appears that isoflavones (soy) had an anti-aging effect on the UV-damaged hairless mice model."
Though more research needs to be conducted to determine the anti-aging effect that soy has on human skin, these results are promising. Women looking to improve their skin and minimize the appearance of black skin dark spots should consider using an African American skin care products that contains soy.
