Simulated consumer use of a battery-powered, hand-held, portable diode laser (810 nm) for hair removal: A safety, efficacy and ease-of-use study

Lasers Surg Med. 2007 Jul;39(6):476-93. doi: 10.1002/lsm.20518.


Background and objectives: Safety, efficacy and ease-of-use of a hair removal diode laser for consumer use were evaluated.

Study design/materials and methods: The treatment group consisting of 77 appropriate users measured safety and efficacy from three self-administered treatments. The non-treatment group consisting of 44 inappropriate users measured safety from delivery of a single laser pulse.

Results: The mean hair reduction was 61% 3 weeks after the first treatment, 70% 3 weeks after the second treatment, 60% 1 month after the third treatment, 24% 2 months after the third treatment, 6% 3 months after the third treatment, 41% 6 months after the third treatment, 31% 9 months after the third treatment, and 33% 12 months after the third treatment. The only observed side effect for appropriate users was transient erythema.

Conclusions: In simulated consumer use, the laser was highly effective at removing hair with minimal side effects for appropriate users.
