Six-month follow-up multicenter prospective study of 368 patients, phototypes III to V, on epilation efficacy using an 810-nm diode laser at low fluence

Laser hair removal is currently a popular cosmetic procedure. Traditional high-fluence laser treatment for hair elimination is associated with discomfort and adverse events and it is restricted to low phototype skins. A multicenter study of hair epilation with low fluences and high repetition pulse rate using an 810-nm diode laser was carried out on 368 patients (phototypes III to V) to test its efficacy in a 6-month follow-up after five treatments on the face and various body areas. Objective and subjective assessment as well as histologies show a high index of patient satisfaction due to high efficacy of hair elimination, also proved histologically by the damage observed at hair structure level. Results obtained a high degree of patient satisfaction and a low index of adverse events. Laser epilation was well accepted regarding discomfort and was also complication-free for dark and tanned skins. Treatment is easy to conduct and requires adapting the movement of the hand-piece to a constant speed in order to achieve high-energy deposit on tissue avoiding risks of burning.
