Abstract: This invention pertains to improved methods of classifying skin types as well as improved methods for determining the appropriateness of products and evaluating methods for treating particular skin. The methods typically utilize a “skin type” database containing one or more quantitative measures (e.g., NMR data) of skin properties. The database can optionally include various qualitative measures of skin as well (e.g., Glogau scale and/or Fitzpatrick scale values).
