Thank you for your questions! **1. Is it safe for the neck?** Yes, this device is designed for use on the face, neck, and body when used as directed. Start at a low intensity and avoid direct exposure to the eyes. **2. Where can I get eye protection?** One pair of protective goggles is included in the package. Additional eye protectors are available in our [Accessories](https://www.freyara.com/accessories) section. **3. Does it help with collagen, wrinkles, and skin glow?** Yes! The 630nm red light and 850nm near-infrared light may help support collagen production, improve the appearance of fine lines and wrinkles, and promote smoother, healthier-looking skin with consistent use. **4. Can it help with shoulder, back, and knee pain?** Red and near-infrared light therapy may help relieve mild muscle soreness and discomfort in these areas. However, results vary, and it is not a substitute for medical treatment of persistent joint or back pain. We hope this helps! 

Yes, you may feel a slight warmth on your skin when the device is turned on, especially at higher settings or when the infrared/NIR mode is activated. This is normal. However, the sensation should be a comfortable warmth—it should not feel hot, painful, or cause a burning sensation. If you experience significant heat, redness, itching, or discomfort, stop using the device immediately and lower the setting, increase the distance, or shorten the treatment time. When using the device on your face, please wear protective eyewear to avoid direct exposure of the light source to your eyes.
