Patent ID: 8114022

Claim:
A business method for generating advertising claims, the method comprising the steps of: (a) determining the before use thickness of the Stratum Corneum on an area of a test subject's skin comprising the steps of: i. measuring the concentration profile of a Raman-active material as a function of depth within the test area using Confocal Raman Spectroscopy; then ii. processing the Confocal Raman Spectroscopy data obtained to determine said before use thickness of the Stratum Corneum; (b) providing said test subject with a personal care composition and instructions for use of said personal care composition; (c) determining the after use thickness of the Stratum Corneum on an area of a test subject's skin after the use of said personal care composition comprising the steps of: i. measuring the concentration profile of a Raman-active material as a function of depth within the test area using Confocal Raman Spectroscopy; then ii. processing the Confocal Raman Spectroscopy data obtained to determine said after use thickness of the Stratum Corneum; (d) calculating, using a computer, the effectiveness of the skin care composition wherein the thickness of the Stratum Corneum before and after the application of the personal care composition are input as parameters when calculating the effectiveness of the personal care composition; (e) utilizing said effectiveness of the personal care composition to generate said advertising claims.
