Real scientific value of popular non-invasive hydratation devices used in clinical studies
Short talk
Session 3: Hydration evaluation, what's new?
Day 2
10:40 am
Hydration remains a cornerstone parameter in dermatological research and cosmetic
evaluation, with the tools available to quantify it continuing to evolve. At Cosmetotest
2026 in Lyon, Tim Houser will present new insights into the measurement of skin
hydration, building on his 2025 contribution on skin color assessment. This year’s focus
will be an exploration into the real scientific value of popular non-invasive devices widely
applied in clinical and cosmetic studies. The presentation will highlight methodological
differences, sensitivity, and reproducibility of the instruments, with particular attention to
their performance in controlled study environments. By examining case data and
practical applications, Houser will discuss how these devices inform product testing and
innovation in cosmetic science. The session aims to provide researchers and industry
professionals with a critical perspective on hydration measurement technologies,
encouraging dialogue on standardization and best practices.

Tim Houser is President and Scientific Director of Dermico, as well as Chief Scientific
Officer of KGL Skin Study Center. With extensive expertise in non-invasive skin
measurement technologies, Houser is a leader in advancing methods for evaluating
skin color, hydration, and barrier function in both clinical and cosmetic contexts. Known
for bridging technical rigor with practical application, he has presented widely on
dermatological instrumentation, including his 2025 Cosmetotest talk on skin color. In
2026, he will share new insights on hydration measurement technologies.
Cortex Technology has spent more than 40 years advancing the science of skin
measurement, supporting researchers who require high precision, reproducible data for
product development and clinical evaluation. Our instruments are engineered to quantify
key biophysical parameters such as hydration dynamics, elasticity, TEWL, color, collagen,
skin thickness and others with exceptional sensitivity and stability. We design every
device with scientific rigor in mind—robust calibration, consistent probe to skin interaction,
and data outputs optimized for statistical analysis. Whether used in controlled laboratory
studies or large scale clinical trials, our solutions help researchers capture subtle changes
in skin physiology and validate claims with confidence. At Cosmetotest 2026, we will
highlight our newest developments in non invasive skin assessment technologies,
enabling deeper insight and supporting the industry’s demand for evidence based
innovation. Cortex Technology remains committed to empowering scientists with reliable
tools that advance the understanding of skin biology.
