In modern medical facilities, laser is becoming more important in aesthetic and medical applications. However, inappropriate laser irradiation can result in harmful effect such as thermal burn injury. This is owing to the thermal response of the skin due to laser irradiation is not well understood. In this study, the thermal response of skin to laser radiation was investigated under the effects of wavelength, laser intensity and incident time. The transient bioheat model was considered and

The amount of energy absorb is significantly higher in the shorter wavelength range and with the increasing intensity. Further, the darker skin color result in higher laser absorption. The obtained values provide an indication of the limitations that must be considered during laser-induced thermotherapy.
