In addition to being used at home this red light therapy for face also meets the needs of going out such as at work training traveling or on business trips. No longer need to interrupt your red light therapy even for a short time out truly meeting the needs of daily use 【Innovative Design】The infrared light therapy is equipped with a detachable stand. Take off the stand you could hold and use the light therapy lamp for the specific part like face neck shoulders arms waist belly legs knees etc. Besides it could be placed on the ground and adjusted the angle to up to 160° with the magnetic stand combined. Compared with the other red light panels seen on the market our red light therapy for body comes with a more flexible adjustment so that we could enjoy this red light therapy in a more comfortable and effective state 【Optical Lens Tech.】Our infrared red light therapy are innovatively added optical lenses to make the emitted light more focused improving the luminous efficiency of the entire light therapy panel.

The dual-chip lamp beads contributes to our led light therapy for face to enable three wavelength modes. (Red \u0026amp; Infrared light \/ Red light \/ Near infrared light) The redlight-therapy device face will autostop after finishing light therapy devices. We would like to recommend that use it about 20-30mins a day and insist to reach the effect 【3 Wavelength Modes and Superior Efficacy】Our red light therapy panel contains 225 lamp beads with wavelengths of 660nm (red light) and 850nm (near-infrared light) which is the best combination of wavelengths.The 660nm red light can be effectively absorbed by the skin improving the appearance of the skin making your skin in an active state and maintaining its health.
