Method and system for characterizing tactile perception

摘要

An acoustic emission system for objectively measuring tactile skin attributes and methods of using same. The system includes: (A) Means for generating an acoustic emission signal from skin; (B) Means for collecting, storing and displaying said emission signal; (C) means for correlating said emission signal with an attribute of said skin; wherein said system is used as a clinical tool to evaluate efficacy of cosmetic skin care and/or cleansing products. A cosmetic product selection system is also provided which includes a cosmetic composition for reducing the appearance of undesirable skin attributes and an acoustic emission system associated with the composition. A method for assessing tactile skin attributes using an acoustic emission system, as well as of evaluating progress of the combat against the signs of undesirable skin attributes occurring over a period of time within which the composition is applied to an area of skin being monitored is provided.
