Introduction
Dermatitis is a broad term that includes eczema, allergic dermatitis, and irritant dermatitis. These conditions often cause redness, itchiness, swelling, and discomfort. Many people look for gentle, non-drug solutions to reduce flare-ups. Red light therapy has recently gained attention as a natural option for soothing irritated skin.
But does it actually work for dermatitis? Let’s explore.
How Dermatitis Develops
Dermatitis can be triggered by:
-
Inflammation
-
Skin barrier dysfunction
-
Allergic reactions
-
Environmental irritants
-
Chronic dryness
Successful treatment requires reducing inflammation and restoring the skin’s protective barrier—exactly what red light therapy helps with.
How Red Light Therapy Helps Dermatitis
Red light therapy uses wavelengths such as 630–660 nm, which target inflammation and promote healing.
Key Benefits
✔ Reduces inflammation in irritated skin
✔ Improves moisture retention
✔ Supports skin barrier repair
✔ Decreases redness and swelling
✔ Promotes cellular regeneration
These effects help calm dermatitis flare-ups naturally and safely.
