Lipid study uncovers anti-aging potential
with strong anti-aging potential from tests on the ability of
lipids to fight skin aging.
Published in the Journal of Lipid Research, the study looked into the impact of seven naturally occurring fat molecules on skin aging. Effect on collagen The researchers said three of the lipids examined were capable of preventing UV-radiation from reducing collagen expression and increasing levels of matrix metalloproteinase (MMPs). They also said the molecules even increased collagen in undamaged skin cells. Most effective lipid Of these potential ingredients, phosphatidylserine (PS) was identified as the most promising for anti-aging skin care products. The scientists therefore decided to test the molecule on human skin. They applied a 2 percent PS solution to small areas of the buttock in both young and old volunteers and gave the skin a dose of UV radiation. In both natural and UV-induced aging, the study claimed the treatment prevented collagen reduction and increased MMPs. Anti-wrinkle potential The scientists said their finding suggest that PS may be a simple and natural way to fight wrinkles. Nonetheless they called for larger and longer trials to confirm its therapeutic benefits.
