摘要

In modern medical facilities, laser technology is becoming more important in aesthetic and medical applications.However, inappropriate laser irradiation can result in harmful effects such as thermal burn injury. This occurs because thermalresponse of the skin due to laser irradiation is not well understood. In this study, the thermal response of skin to laser radiationwas investigated under the effects of wavelength, laser intensity, and incident time. The transient bioheat model was consideredand solved numerically using the finite element method. This study demonstrated that the skin temperature distribution dependsstrongly on the wavelength, intensity, and skin color type. The amount of energy absorption is significantly higher in the shorterwavelength range and with increasing intensity. Further, a darker skin color results in higher laser absorption. The obtainedvalues provide an indication of the limitations that must be considered during laser-induced thermotherapy.
