1. Product Introduction
The 660nm LED Red Light Therapy Pen is a compact, handheld device designed for targeted photobiomodulation therapy. It uses a powerful 660nm red LED light to deliver non-invasive treatment to small or specific areas of the body. Ideal for personal or professional use, the pen promotes skin repair, reduces discomfort, and accelerates tissue recovery. Its ergonomic design ensures easy handling, making it suitable for daily home therapy or travel use.
2. Wavelength Principle Introduction
The 660nm wavelength belongs to the visible red light spectrum, known for its strong absorption by mitochondria in skin and muscle cells. When applied to the skin, it enhances cellular energy (ATP) production, improves microcirculation, and stimulates collagen regeneration. This wavelength penetrates about 3–5 mm into tissues, making it ideal for surface-level conditions such as wounds, acne, inflammation, and pain in shallow muscles or joints.
3. Application Scope
This red light therapy pen is suitable for a wide range of uses, including skin rejuvenation, acne and scar reduction, wrinkle improvement, and minor wound healing. It can also help relieve localized pain caused by arthritis, joint stiffness, muscle fatigue, or inflammation. The focused beam design allows accurate treatment on small target areas such as fingers, knees, or facial zones, offering safe and effective therapy for both beauty and pain relief applications.
4. Buttons and Usage Suggestions
The device features a single multifunctional button for simple operation. Press the button to switch among three adjustable modes: continuous high power, continuous low power, and pulsed high power. For best results, aim the light at the treatment area from a short distance for 5–10 minutes per session, 1–2 times daily. Always wear protective goggles during use. Regular and consistent treatment helps achieve optimal healing and rejuvenation effects.
