FOCUS#14: Testing expert discussion, all you need to know about the hydration evaluation

The FOCUS #14 is here, with all you need to know about expert discussion around hydration claim evaluation!

We are delighted to announce the publication of FOCUS #14, the latest edition of Skinobs’ semi-annual expert panel dedicated to the rapidly evolving field of hydration claim evaluation.

Hydration: the golden claim of the skincare industry

Hydration remains, without question, the golden claim of the skincare market. It is the foundation on which countless product lines are built, the promise consumers look for first, and the benchmark against which efficacy is most often judged. As consumer expectations rise and competition intensifies, hydration claims have never been so scrutinized, nor so central to product positioning.

This growing demand for proven, science-backed hydration benefits is driving a wave of innovation in testing methodologies. Brands and laboratories are seeking more precise, reliable, and sophisticated ways to measure how a product truly performs on the skin, from surface moisturization to deep barrier function, in order to substantiate claims that genuinely resonate with consumers.

This edition provides an essential overview of the current landscape, highlighting how technological innovation, biological understanding, and integrated evaluation strategies now converge to support hydration-focused product development. From corneometry and TEWL (transepidermal water loss) measurement to AI-assisted imaging, from molecular exploration of the skin barrier to standardized performance assessments, the tools available to R&D teams to evaluate and substantiate hydration have never been more sophisticated.

FOCUS #14 brings together leading experts who share their perspectives on these evolutions, offering valuable insights for cosmetic scientists, formulators, marketers, and anyone involved in skincare innovation. Whether you are exploring new claim possibilities, refining your hydration testing roadmap, or simply seeking inspiration for future developments, this edition will help you navigate the complex and multidisciplinary world of skin hydration evaluation.

By gathering diverse viewpoints, this publication reinforces Skinobs’ mission: to connect the cosmetics industry with reliable, cutting-edge testing solutions and to empower professionals with the knowledge they need to substantiate hydration claims and demonstrate product performance with confidence.
