Handheld device for determining skin age, proliferation status and photodamage level
First Claim
1. A probe for measuring at least one parameter of skin condition, comprising:
- an optical radiation source for generating light to be projected upon the skin to be examined;
an optical radiation detector for measuring the light signal from the skin in response to the light projected on the skin by the optical radiation source and generating an output signal indicative of the value of the at least one parameter, said probe being a self-contained unit that may be held in a human hand.

Abstract
A self-contained, handheld probe for measuring at least one parameter of skin condition, has one or more light sources that may be used to project light upon the skin. The light projected is of a selected wavelength known to generate a specific fluorescence that is indicative of the skin parameter of interest in accordance with a known correlation. To produce the proper excitation light, a light source generating that wavelength is used or a broader spectrum of light is selectively filtered to pass the wavelength of interest. Lenses, fiber optic elements or waveguides may be employed to project the light onto the skin at a specific location and/or to deliver the skin response to a light detector, which measures the light signal from the skin. and generates an output signal indicative of the value of the at least one parameter. The probe may be used to measure skin age, photodamage and/or proliferation.
