Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

A collagen-based drinkable supplement improved several objective measures of skin health and aging in women over 35.

The question

Does a drinkable nutraceutical containing collagen peptides and other micronutrients improve skin aging and skin health parameters?

What they tested

The drinkable nutraceutical ELASTEN will improve skin hydration, elasticity, roughness, and density compared to a placebo.

How they did it

This was a randomized, placebo-controlled, blind study involving 72 healthy women aged 35 years or older. 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.

What they found

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.

What it means

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.

Where the published abstract does not list limitations, we say so rather than inventing them. Read the full paper on PubMed before drawing conclusions.

Collagen Peptides

Collagen production declines with age, contributing to skin laxity, joint wear and connective-tissue fragility. Randomised trials of oral collagen peptides report measurable improvements in skin elasticity and joint comfort, making collagen a connective-tissue-focused element of a longevity routine.
