Red light therapy for eczema

Eczema is a chronic skin condition where the skin overreacts to external stimuli, leading to recurrent inflammation, itching, and a weakened skin barrier. Many people seek complementary treatments in addition to creams or medication. Red light therapy is one such option, and there is increasing scientific evidence that it actually works.

Red light versus UV light therapy: not the same

A common confusion: light therapy for eczema in the hospital uses UV light, which is very different from red light therapy. UV therapy does work for eczema but carries risks such as skin damage and an increased chance of skin cancer with long-term use. Red light therapy does not use UV radiation and therefore does not carry that risk.

How does red light work for eczema?

Red light therapy penetrates deep into the skin layers where inflammatory reactions occur. There, it activates the mitochondria in the skin cells, leading to increased cellular energy (ATP) production. This extra energy supports the repair of the skin barrier and inhibits the inflammatory response.

Red light (620 to 700 nm) works superficially and is ideal for skin problems such as eczema. Near-infrared penetrates deeper but is less relevant than red light for superficial skin complaints.

Specifically, red light for eczema can have the following effects: inhibiting skin inflammation, reducing itching by calming irritated tissue, strengthening the skin barrier through improved cell regeneration, and improving blood circulation so that skin cells are better supplied with oxygen and nutrients.

What does research say?

Researchers concluded in a study on red light therapy for eczema that they believe red light therapy can become a new effective therapy for eczema, where even rare and short treatments made a significant difference. No side effects were reported during or after the treatments.

The evidence is promising but not yet as strong as for some other applications such as skin rejuvenation or allergic rhinitis. Red light therapy is therefore considered a complementary treatment, not a replacement for medical policy.

How do you apply it?

For best results, it is recommended to apply red light therapy at least 3 to 5 times a week. A session typically lasts 5 to 10 minutes. Place the device approximately 30 to 45 centimeters away from the skin area to be treated and ensure that the light falls directly on the skin, without clothing or creams.

Preferably use the device on clean skin. Apply moisturizing cream after the session, not before, so that the light can reach the skin unimpeded. Pay attention to your skin's reaction in the first few weeks: in case of excessive redness or irritation, gradually increase the sessions.

Safety and when to consult a doctor

Red light therapy for eczema is safe for most people. No UV radiation is emitted, and the treatment is non-invasive. Use light therapy as a supplement, not as a replacement for medical treatment. For severe eczema, consultation with a specialist is always necessary. Also, consult a doctor if you are taking medication that makes you light-sensitive, or if your eczema suddenly worsens.
