Red Light Therapy for Eczema: Calming Itch and Inflammation

Eczema (atopic dermatitis) brings itch, redness, and flare-ups that are hard to soothe. Can red light therapy help calm it? Here's an evidence-minded look.

How red light may help eczema

Red and near-infrared light have anti-inflammatory effects and support the skin barrier, which may reduce the itch-scratch cycle and redness that drive eczema flares. It's gentle and drug-free, unlike steroids.

What to expect

Red light isn't a cure, but used consistently it may help calm irritated areas and support healing between flares. Keep sessions short and gentle, and moisturize afterward.

How to use it safely

• Treat clean, bare skin with a low, comfortable dose.
• Avoid use on broken or weeping skin during severe flares unless your doctor approves.
• Be consistent — a few sessions per week over time.

If you have moderate-to-severe eczema or take photosensitizing medication, check with your dermatologist first. See our broader safety guide. Educational only; not medical advice.
