Participants were divided into two groups: 36 received the nutraceutical (2.5 g collagen peptides, acerola fruit extract, vitamin C, zinc, biotin, vitamin E complex) and 36 received a placebo for twelve weeks. Skin assessments were performed using corneometry for hydration, cutometry for elasticity, silicon skin replicas with PRIMOS for roughness, and skin sonography for density. The verum group was followed for an additional four weeks without the product to assess the sustainability of effects. ## Results The test product significantly improved skin hydration, elasticity, roughness, and density. Statistically significant differences were observed between the verum group and the placebo group for all tested parameters. These positive effects were largely retained during the four-week follow-up period. Subjective assessments by participants were consistent with the measured effects, and the nutraceutical was well tolerated. ## Conclusion The drinkable nutraceutical ELASTEN significantly improves objective parameters of skin aging and health, including hydration, elasticity, roughness, and density, with sustained effects after product cessation. ## Limitations The abstract does not explicitly state any limitations of the study. ## Verbatim from the abstract > the product significantly improved skin hydration, elasticity, roughness and density ## Where this study is used on Magellan This paper is one of the citations behind the evidence grade on the pages below.
