Collagen Peptides Linked to Improved Appearance of Damaged Skin

While you can’t totally prevent wrinkles, there are steps that people can take if they want to try to have younger-looking skin. A recent study suggests that taking a daily supplement of five grams of collagen peptides derived from fish may improve skin moisture, elasticity, and wrinkles.


Participants in the study included 85 healthy Chinese women who were given either supplements with collagen hydrolysate with a low or high amount of bioactive collagen peptides or a placebo daily for eight weeks. The two collagen peptides used were prolyl-hydroxyproline and hydroxprolyl-glycine.


At the conclusion of the study, the women who took the higher dose supplements had significant improvements in skin moisture, elasticity, wrinkles, and roughness. While both doses showed improvements in skin moisture, but the lower dose one was not associated with changes in elasticity, wrinkles or roughness.


Researchers from Nitta Gelatin in Japan conducted the study. It was published online ahead of print on February 10, 2016, in the Journal of the Science of Food and Agriculture.


Previous studies suggest that collagen peptides may help with joint and bone health, particularly as we get older. Because collagen peptides dissolve in water, it’s best to take them in the form of a drink supplement.
