Earlier this year, Chenbin Liu and co-authors from the School of Chemistry and Chemical Engineering at Nanjing University (Nanjing, China) published in the IEEE Sensors Journal on the use of a mobile phone to detect skin mechanical properties and hydration.

According to the article abstract, one widely used method by clinicians to detect skin hydration is the skin turgor or pressure test, which is a visual assessment of skin’s mechanical properties. While no special equipment is necessary, it lacks quantification and is hard to practice by non-experts.
