Collagen Peptides May Improve Skin Elasticity

Aging results in decreased skin elasticity, with contributes to wrinkles. A recent study suggests that taking oral supplements of a specific group of collagen peptides called collagen hydrolysate may improve skin elasticity by as much as 30%.

Participants in the study included 69 women between the ages of 35 and 55. Over the course of eight weeks, they took either 2.5 or 5 grams of a collagen peptides oral supplement or a placebo once a day.

The researchers found that skin elasticity was improved in both of the supplement groups at the four and eight-week point and that both doses resulted in statistically equal results. They also found that the results were more pronounced in women over the age of 50.

They also noted a positive influence on skin moisture (an 11% improvement) and on skin evaporation (a 6% improvement) in women over 50.

Additionally, the effects were still noticeable after a 4-week washout period, which suggests that this supplement may have long-lasting benefits.

Researchers from the University of Kiel in Germany, the Collagen Research Institute in Germany, Skin Investigation and Technology in Germany and the University of Sao Paulo in Brazil conducted the study. It was published online ahead of print on August 14, 2013, in Skin Pharmacology and Physiology.

Collagen peptides aren’t the only natural way to help retain and improve skin elasticity. Previous research has linked French maritime bark extract and taking regular antioxidant supplements with improved skin health.
