Red light therapy is known for its benefits in skin rejuvenation, pain relief, and muscle recovery. But a common question is: Do you need direct skin exposure, or can it work through clothes?
Does Red Light Therapy Work Over Clothing?
The short answer is no. For the best results, red light therapy should be applied directly to bare skin.
Clothing, even if thin, blocks or scatters a significant amount of red and near-infrared light. Since these wavelengths need to penetrate the skin to reach the cells, wearing clothes reduces effectiveness.
Why Direct Skin Exposure Matters
-
Deeper Penetration: Red and near-infrared light can reach several millimeters below the skin, but only without barriers.
-
Better Results: Direct exposure ensures maximum absorption, stimulating collagen production, reducing inflammation, and improving circulation.
-
Consistent Coverage: Clothes can create shadows or uneven areas, leading to less effective treatment.
Tips for Effective Red Light Therapy
-
Wear minimal clothing or expose the target area during sessions.
-
Keep the device close to the skin (usually 6–12 inches away, depending on instructions).
-
Follow recommended session times for safe and optimal results.
Key Takeaway
You should not rely on red light therapy through clothes. For the therapy to work effectively, direct skin contact is essential. Removing barriers ensures your skin and cells absorb the full benefits of the treatment.
Safety Note: Always wear eye protection during sessions, as red light can be harmful to the eyes if unprotected.
