WEDNESDAY, Aug. 21, 2024 (HealthDay News) — A drink containing collagen peptides (CP), including tripeptides and elastin peptides (EP), has a positive effect on the skin health of young and middle-aged women, according to a study published in the June issue of Journal of Dermatology and Cosmetic Technology.

Shan Lu of Shenzhen Porshealth Bioengineering Co. in China and colleagues conducted a single-center randomized trial to investigate the effects of an orally administered collagen drink combining CP and EP on the skin health of young and middle-aged women. Participants consumed the WONDERLAB^® Fish collagen tripeptide drink over a period of eight weeks.

The researchers found that compared to the placebo group, the group consuming the collagen drink had significant improvements in skin hydration (39.19 percent increase) and reduced transepidermal water loss (33.45 percent decrease); skin elasticity, dermal collagen content and skin smoothness increased (25.37, 21.64 and 2.85 percent increase, respectively); and pore size, wrinkle length and skin roughness decreased (7.94, 18.09 and 15.32 percent decrease, respectively). Pore volume decreased by 60 percent; visual assessments showed a decrease in skin luminosity and skin smoothness index by 15.20 and 22.55 percent, respectively. Mass spectrometry revealed significant increases in collagen efficacy components, including blood pH and glycine-proline-hydroxyproline levels.

The beverage product “effectively improved skin hydration, elasticity and firmness, increased radiance and smoothness, reduced transepidermal water loss and wrinkles, minimized pores and roughness, and increased collagen content in the dermal layer as well as effective collagen components in the body,” the authors write.
