Know What You’re Trying to Achieve
Your goal influences the type of device you should pick:
Skin rejuvenation & anti‑aging — focus on devices with strong red light wavelengths (~630–660 nm).
Deeper tissue recovery (muscles, joints, pain relief) — include near‑infrared (NIR) (~810–850 nm) in the specs.
General wellness & circulation support — Full‑body panels or larger devices with both wavelengths work best.
Why this matters:
Different wavelengths penetrate to different depths — red light is closer to the skin’s surface while NIR reaches deeper tissues.
2️⃣ Check the Wavelengths
Look for devices that clearly list their light wavelengths:
Red light (~630–660 nm): Best for skin health, collagen stimulation, and superficial tissue effects.
Near‑Infrared (~810–850 nm): Better for deeper tissues, muscle recovery, pain, and inflammation.
Tip: Avoid devices that don’t specify wavelengths — if they can’t tell you the ranges, the therapeutic benefit is hard to verify.
3️⃣ Look at Irradiance — Not Just Wattage
Irradiance (mW/cm²) shows how much light energy reaches your skin.
Devices with higher irradiance deliver more effective therapy in shorter time.
Aiming for 30–100+ mW/cm² at treatment distance is a good benchmark for at‑home devices.
👉 More LEDs doesn’t always mean better therapy — it’s about energy delivered to the body.
4️⃣ Choose the Right Size & Coverage
Different devices suit different use cases:
Small/Portable Units — great for spot treatments (e.g., face masks, handheld devices).
Mid‑Size Panels — ideal for larger muscle groups or multiple body parts.
Full‑Body Panels — best for whole‑body therapy (good for general wellness, recovery, and circulation).
Think about where and how often you’ll use the device. Larger panels take up more space but treat more area faster.
5️⃣ Safety & Certifications
Choose devices that are:
✔ FDA‑cleared or FDA‑listed (or CE/other credible safety marks).
✔ Built with quality LEDs and tested safety standards.
✔ Designed with eye safety in mind
