SKIN WRINKLE EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for non-invasively and quantitatively evaluating a state of wrinkles on a skin owing to a change in the interior of the skin such as a corium layer, etc. SOLUTION: The state of wrinkles on the skin is evaluated based on the orientation of collagen in the interior of the skin. Extra-short pulse light is applied preferably to the interior of the skin to detect second harmonic generation light (SHG light) generated. Measurement of the orientation of collagen in the interior of the skin is performed based on a detection result thereof. COPYRIGHT: (C)2010,JPO&INPIT
