Abstract:
1. A method of evaluating treatment efficacy on a test subject comprising the following steps: 1) identifying a sub-population that includes the test subject; 2) creating a data set by measuring skin firmness at the jowls, skin firmness at the outer canthus, forehead lines, under eye lines, in vivo fluorescence related to glycation, lip lines and skin texture for a set of individuals within the sub-population; 3) using a computer processor to apply factor analysis to the data set to identify those factors that account for at least 50% of the observed skin aging; 4) using a computer processor to apply regression analysis to determine a linear combination of the factors that best fits the data; 5) measuring the test subject's skin firmness at the jowls, skin firmness at the outer canthus, forehead lines, under eye lines, in vivo fluorescence related to glycation, lip lines and skin texture; 6) calculating an objective apparent age score using the linear combination of factors for the test subject; 7) administering to the test subject a course of treatment that affects at least one factor in the linear combination of factors; 8) determining a second apparent age score for the test subject by repeating steps 5 and 6; 9) subtracting the first apparent age score from the second apparent age score; 10) associating a negative difference with an efficacious treatment.
