摘要：
The methods of this invention relate to means for measuring skin hydration. The methods of this invention utilize at least two wavelengths filtered by at least two polarizers to create digital images of skin treated with personal care products. The methods are useful for demonstrating the efficacy of skin care products intended to increase skin hydration and/or protect the skin from dehydration, even when such dehydration is not apparent to the naked eye.
