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.
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.
Previously published standard test methods were used to evaluate the devices tested.
Some of the devices measured in this study showed significant discrepancies between claims made by the manufacturers and the parameters measured.
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.
医疗保健专业人员经常使用激光和强脉冲光（IPL）设备进行脱毛，但迄今为止，家用激光和光技术设备在消费市场上的影响甚微。然而，随着跨国公司进入这个市场，消费者对这类设备的使用将会激增。
本研究聚焦于所测试设备的技术性能，尽管未提供临床数据，但所测量的参数是那些将直接影响毛发减少效果、皮肤有效覆盖范围以及在无意的眼部暴露于光源或针对特定皮肤类型的错误设置方面的安全性的参数。消费者会向有光基治疗经验的医疗保健专业人员咨询建议，本研究为现有的家用设备提供了有用的参考信息。
采用先前发表的标准测试方法来评估所测试的设备。
本研究中测量的一些设备在制造商声称的参数与实际测量的参数之间存在显著差异。
迫切需要尽早批准国际电工委员会（IEC）60601 - 1强光标准草案，该标准将涵盖专业和家用脱毛设备的制造标准。
