Collagen Drink Improves Skin Health in Young and Middle-Aged Women: Study

A collagen drink combining collagen peptides (CP) and elastin peptides (EP) demonstrated significant improvements in skin health among young and middle-aged women according to a recent study. The findings of this study were published in the Journal of Dermatologic Science and Cosmetic Technology.

This research explored the effects of an orally administered collagen drink on the skin health of women aged between 25 and 50 years. While previous studies have shown the individual benefits of CP and EP in vitro and in vivo, this trial was focused on evaluating the combined effects of these peptides in the context of skin health.

The participants in the study were divided into two groups where one received the collagen drink daily for 8 weeks and the other group received a placebo. The primary outcomes measured were the skin hydration, elasticity, transepidermal water loss (TEWL), collagen content in the dermis, pore size, wrinkle length, skin smoothness, and overall skin roughness. Also, mass spectrometry was employed to assess the bioavailability of collagen peptides by measuring specific collagen efficacy components in the blood.

The results were strong, with the collagen drink group showing significant improvements in multiple skin health indicators when compared to the placebo group. There was a remarkable increase (39.19%) in skin hydration among the participants who consumed the collagen drink, this indicates its effectiveness in maintaining moisture levels in the skin. The Transepidermal Water Loss group also experienced a 33.45% reduction which suggested a strengthened skin barrier that reduces moisture loss. Skin Elasticity improved by 25.37%, demonstrating the ability of the drink to restore the skin's natural firmness and resilience. A 21.64% increase in dermal collagen content was observed which reflected the potential of the drink to promote collagen synthesis within the skin.

The study found a 7.94% decrease in pore size and an 18.09% reduction in wrinkle length by highlighting the drink's anti-aging benefits. The participants reported a 2.85% improvement in skin smoothness and a 15.32% decrease in skin roughness, which further contributed to the overall youthful appearance of the skin. The study also revealed a significant reduction in overall pore volume by 60%, as well as decreases in skin luminosity (15.20%) and smoothness index (22.55%), suggesting a notable enhancement in skin texture. Overall, these findings suggest that regular consumption of a CP and EP-enriched collagen drink could be a valuable addition to the skincare regimen of individuals looking to maintain or iprove their skin health as they age.
