Correlation between skin absorbance and skin burns caused by near-infrared laser irradiation in several mammalian species

The purpose of this study is to obtain the relationship between skin absorbance, a rise in temperature on the skin surface, and skin burns in several mammalian species and to estimate burn risk in humans. We measured the skin absorbance of the species by diffuse reflectance spectroscopy and applied a near-infrared pulsed laser to each species on their skin. Laser irradiation raised temperature on the skin surface and caused skin burns in areas with higher absorbance, regardless of the species. We estimated the risk of skin burns for each skin type by comparing skin absorbance between humans and the mammals.
