WG-SP-1103 LED Colorful Photon Rejuvenation Mask Facial Beauty Instrument, Infrared 1. Material: Silicone 2. Battery capacity: 1000mAh 3. Input: 100-240V, 5060Hz 4. Output: 5V 1A 5. It uses the principle of light irradiation, which is safe and simple, and can be reused to maintain facial skin. 6. It improves the activity of cells, promotes cell metabolism, and makes the skin secrete a large amount of collagen and fibrous tissue to fill itself. 7. It accelerates blood return to increase skin elasticity, improves the condition of sallow and dull skin, and thus achieves whitening, skin rejuvenation, anti-wrinkle, spot lightening and other repair effects. 8. It uses 7 different cold light sources, namely red, blue, green, yellow, purple, and cyan blue. Each laser light has different effects and can deal with different skin problems. One instrument has multiple effects, which is practical and affordable. 9. Light source: Red light: wavelength range: 760~622 nanometers; Orange light: wavelength range: 622~597 nanometers; Yellow light: wavelength range: 597~577 nanometers; Green light: wavelength range: 577~492 nanometers; Cyan light: wavelength range: 492~450 nanometers; Blue light: wavelength range: 450~435 nanometers; Violet light: wavelength range: 435~390 nanometers
