The 660nm wavelength is absorbed by the skin's surface layers, supporting cell activity and collagen production. The 850nm near-infrared wavelength penetrates deeper into tissues, promoting circulation and deeper cellular energy support. Using both wavelengths together provides a comprehensive, layered phototherapy experience.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this belt with a portable battery pack?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The belt supports 12V external power banks directly. If you only have a 5V USB power bank, you will need a USB boost cable (not included) to step up the voltage to 12V. For home use, the included AC adapter (compatible with EU, US, UK, and AU plugs) works seamlessly.\u003c\/p\u003e\n\u003ch4\u003eQ: How long should each light therapy session last?\u003c\/h4\u003e\n\u003cp\u003eA: Typical light therapy sessions range from 10 to 20 minutes per area.
