Abstract
The invention relates to methods of measuring the overall elasticity of skin and determining the portion of the overall elasticity that is due to elastic properties and the portion of overall elasticity that is due to viscoelastic properties of the skin and correlating the results of the measurement to an individual's chronological age. The invention also relates to methods of measuring improvements in a person's skin health by measuring elasticity before, during and after human clinical trials of topical and/or oral treatment compositions. The parameters for determining elasticity are based on areas that are defined on a deformation/relaxation curve and require that an inflection point be determined for each skin sample analyzed.
