The study analyzed the thermal effects of laser sources at wavelengths of 694, 755, and 1064 nm with varying fluences to optimize laser hair removal. Using a 3D model of human skin and methods like the Monte Carlo method and Arrhenius formula, it was found that a laser source of 10-15 J/cm² at 755 nm was optimal for light and moderate skin types, while 4.5-10 J/cm² at 755-1064 nm was suitable for dark skin, with a pulse width of 0.1 seconds. These findings aimed to aid in the design and development of effective hair removal devices.
