Should Distance Vary by Body Area?

Yes, distance should vary depending on the body area being treated with red light therapy. Different tissues respond differently to light, and adjusting the distance helps optimize effectiveness.

Facial vs Body Areas

• Face: thinner skin, requires moderate intensity (10–20 cm)
• Muscles: deeper tissue, may benefit from closer positioning
• Joints: often require higher intensity and closer distance

Why Variation Matters

Different areas of the body have different:

• skin thickness
• blood flow levels
• tissue depth

Adjusting distance ensures each area receives the appropriate therapeutic dose.

Conclusion

Yes, distance should vary by body area. Tailoring your positioning improves overall treatment effectiveness.
