Lipid study uncovers anti-aging potential

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.
