A two-layer model of laser interaction with skin: A photothermal effect analysis

摘要

In order to understand the photothermal effect mechanism of laser interaction with skin, we employed a two-layer model to describe the heat generation, transportation, and dispersion in the procedure of laser interaction with skin. A skin temperature distribution corresponding to the laser interaction direction is calculated to describe the time of skin gasification and the possible thermal injury. The magnitude of time is ms. This basic process provides a possible quantitative recognition of the applications of laser in clinical skin care.
