1. A method for determining the presence of moisturizing substances on skin, which comprises providing a moisturizing composition which includes an active material capable of binding with water to form a complex, applying the moisturizing composition to desired areas of the skin to form a film or coating which includes such complex and which inhibits moisture loss from the skin, and subsequently testing skin previously treated with such moisturizing composition for the presence of the active material remaining on the previously treated skin, the presence of which active material is directly correlated to the amount of moisturizer composition remaining on the skin.

Abstract
A method for testing skin for presence of moisturizing substances is provided which method includes the steps of applying to the skin a moisturizer formulation which includes protein, urea and/or glucose and/or other reducing sugar such as fructose all of which bind with water and form a film or coating on the skin which inhibits moisture loss from the skin, and subsequently testing the skin for the presence of protein, urea and/or glucose and/or other reducing sugar remaining on the skin which is directly correlated to the amount of moisturizer formulation remaining on the skin. When it is determined through the testing that there has been at least a predetermined loss of protein, urea and/or glucose or other reducing sugar, additional moisturizer is then applied to the skin.
