How Far Should Handheld Devices Be from Skin?

Handheld red light therapy devices are designed for targeted treatments, meaning distance control is even more critical than with larger devices.

Recommended Distance

• 0–5 cm (direct contact or very close)
• 1–3 cm for sensitive areas

Why Close Distance Works Best

Handheld devices typically have lower output than panels, so being close ensures sufficient energy delivery. This is especially important for:

• joint pain
• muscle recovery
• spot skin treatments

When to Avoid Direct Contact

Avoid pressing too hard or using on broken skin unless the device is designed for it.

Conclusion: Handheld devices work best at very close range or direct contact for maximum effectiveness.
