Claim:
1. A method for determining a concentration of melanin pigment in human skin comprising: a) measuring actual spectral reflectance of skin using a visible light intensity sensing device and recording multi-spectral data using a recording device for retrieval; b) selecting an initial concentration of a type of melanin pigment; c) simulating spectral reflectance using a Monte Carlo simulation, and recording the spectral reflectance simulated from the Monte Carlo simulation; d) comparing and measuring a difference between data of the actual spectral reflectance collected from the visible light intensity sensing device and data of the spectral reflectance simulated from the Monte Carlo simulation; e) determining if the difference between the data of the actual spectral reflectance collected from the visible light intensity sensing device and the data of the spectral reflectance simulated from the Monte Carlo simulation is smaller than an acceptable level; f) altering a concentration of the type of melanin pigment if the difference is larger than an acceptable level; g) repeating steps c), d), e) and f) until the difference between the data of the actual spectral reflectance collected from the visible light intensity sensing device and the data of the spectral reflectance simulated from the Monte Carlo simulation is smaller than an acceptable level; h) estimating the concentration of the type of melanin pigment.
