What Blue Light Therapy Lamps Do
Blue light therapy lamps emit specific wavelengths, often around 400 to 490 nanometers, to target skin cells or influence circadian rhythms. They are commonly used for acne treatment, skin rejuvenation, and seasonal mood support. Devices vary in intensity, panel size, and wavelength specificity.
Key Features to Compare
Look for clinically relevant wavelengths, irradiance levels measured in milliwatts per square centimeter, and treatment timer controls. Larger panels cover more area, while smaller devices target specific zones. Check for FDA registration or equivalent certifications, and confirm whether the lamp includes protective eyewear. For a detailed overview of device types and safety considerations, see this guide from the American Academy of Dermatology.
How to Choose and Use Safely
Match the lamp to your goal: lower-intensity devices suit daily mood support, while higher-intensity options may be used for short acne or skin sessions. Follow manufacturer timing and distance guidelines to avoid eye or skin irritation. Consult a dermatologist if you take photosensitizing medications or have a skin condition.
