Measurement of home-use laser and intense pulsed light systems for hair removal: preliminary report.
BACKGROUND
Laser and intense pulsed light (IPL) devices are used routinely by healthcare professionals for hair removal, but laser and light technology devices intended for home use have so far had little impact in the consumer market. However, as multinational companies enter this market, there will be an explosion in the use of such devices by the consumer.


OBJECTIVE
This investigation focuses on the technical performance of the devices tested and although no clinical data are presented, the measured parameters are those that will directly impact efficacy in hair reduction, efficient coverage of skin, and safety in terms of unintentional eye exposure to the light source or incorrect settings for a given skin type. Consumers will consult healthcare professionals with experience of light-based therapies for guidance and this study provides useful reference information on available home-use devices.


METHODS
Previously published standard test methods were used to evaluate the devices tested.


RESULTS
Some of the devices measured in this study showed significant discrepancies between claims made by the manufacturers and the parameters measured.


CONCLUSIONS
There is an urgent need for early ratification of the draft international IEC 60601-1 intense light standard, which will encompass manufacturing standards for both professional and home-use hair removal devices.
