research Optothermal response and Tissue Damage analysis during Laser Hair Removal

February 2020 in “Journal of Physics Conference Series”

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.
