Discussion of evaluating methods for photorejuvenation

摘要

Photorejuvenation is a promising technique for esthetics. But evaluating approach for efficacy of photorejuvenation is relatively behind demand. In this study, after discussion of current techniques, a novel evaluating method for photorejuvenation which combines reflectance and fluorescence spectroscopy is proposed. Laser induced autofluorescence spectroscopy can be used to detect biochemical information from depth of skin. Tristimulus values which reflect the color of skin can be obtained by diffuse reflectance spectroscopy. So combination of the reflectance and fluorescence spectrum is expected to be a promising tool for evaluating efficacy of photorejuvenation.
