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

Abstract

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.

Clinical assessment of a new 755 nm diode laser for hair removal: Efficacy, safety and practicality in 56 patients

“…On average, we consider that the clearances achieved were good in the context of the literature , and very good in comparison with our previous experience with other equipment . The efficacy percentages obtained appear lower than those achieved by Paasch et al in a single patient with more suitable hair removal characteristics, using lower (and less painful) fluences, with the same laser .…”

Laser Hair Removal: A Review

“…Studies using the diode laser have recently suggested a shift away from the criterion standard high‐fluence devices in favor of a low‐fluence (5–15 J/cm 2 ) approach. The latter provides comparable hair reduction, less discomfort, and fewer adverse effects even when treating phototype V skin and tanned individuals . The most common side effects were slight and transient erythema and pigmentary changes.…”

Permanent hair reduction with a home‐use diode laser: Safety and effectiveness 1 year after eight treatments

“…Lastly, it is interesting to compare the current results for this home‐use device to published results for prescription‐use devices. To this end, Table 4 summarizes some of the published results for diode lasers, in which it can be seen that a wide range of results are reported with long‐term hair removal (6 months or more) ranging from at least 34% to 65% under a variety of conditions 2, 3, 9, 18–24. In light of this, the present study demonstrates that the home‐use laser of the current study can produce results that are generally comparable to professional prescription‐use diode lasers when used in a series of treatments on indicated users and according to its instructions for use.…”
