Monte Carlo Simulation of Light Distribution in Aging Skin
XIAO Zhengying
Abstract：To study photon transport in aging skin , on the basis that aging skin seven -layer model was built , light distribution of infinitely narrow photon beam , circularly flat beam and Gaussian beam in skin tissue were stimulated by means of monte carlo method so as to study difference between young skin and aging skin .The result shows that absorption energy density in epidermis of aging skin is smaller;dermis is on the contrary;fluence rate is larger;depth of penetration of photon is higher;in comparison with Gaussian beam , fluence rate of circularly flat beam is more uniform in radial direction distribution and suitable for skin rejuvenation in large area .
