Research Summary
Skin hydration is a complex process that influences the physical and mechanical properties of the skin. Over the years, various technologies have emerged to assess this parameter, with the current standard being electrical probe-based instruments. However, these instruments are limited in their ability to provide detailed information, prompting the development and use of more sophisticated spectroscopic and imaging methodologies.
These advanced techniques allow for in-depth skin analysis, offering insights into skin structure and composition. Modern imaging and spectroscopic methods have revolutionized skin research in both dermatological and cosmetic fields. They are now frequently used in conjunction with traditional methods to comprehensively assess both healthy and pathological skin.
This article reviews the current techniques employed in measuring skin hydration, providing an overview of their principles of operation and their applications in skin-related research.
