Research Summary:
The purpose of this randomized, placebo-controlled, blind study was to investigate the effects of the drinkable nutraceutical ELASTEN® (QUIRIS Healthcare, Gütersloh, Germany) on skin aging and skin health. The drinkable ampoules provide a blend of 2.5 g of collagen peptides, acerola fruit extract, vitamin C, zinc, biotin, and a native vitamin E complex. This controlled interventional trial was conducted with 72 healthy women aged 35 years or older. Participants received either the food supplement (n = 36) or a placebo (n = 36) for twelve weeks.
A skin assessment was performed based on objective validated methods, including corneometry (for skin hydration), cutometry (for elasticity), silicon skin replicas with optical 3D phase-shift rapid in-vivo measurements (PRIMOS) (for roughness), and skin sonography (for density). The verum group was followed for an additional four weeks, without intake of the test product, to evaluate the sustainability of the changes induced by the product.
The test product significantly improved skin hydration, elasticity, roughness, and density. The differences between the verum group and the placebo group were statistically significant for all test parameters. These positive effects were largely retained during the follow-up period. The measured effects were fully consistent with the subjective assessments of the study participants. Additionally, the nutraceutical was well tolerated.
