New 3D in Silico Model of Hair and Skin Heating During Laser Hair Removal

The efficacy and safety of conventional laser hair removal technology is fundamentally based on clinical case studies. However, the internal temperature of hair during treatment and thus the efficacy of the laser pulse cannot be measured or evaluated. Also the level of heat that reaches the surrounding skin tissue is just estimated in order to prevent burning. In this sense, any method that enables the measurement of the temperature that reaches the hair and skin during a laser pulse is a potential tool to improve laser hair removal technique and to increase the safety of laser technology. Here we develop new numerical multiphysics simulation software to simulate the hair removal process. We create 3D models of dermal tissue that include the epidermis, dermis and hair
