From the Research

Red light therapy (RLT) is not a recommended treatment for eczema based on the provided evidence, which focuses on topical corticosteroids and other treatments. The most recent and highest quality study, 1, found that potent topical steroids, Janus kinase inhibitors, and tacrolimus 0.1% were consistently ranked as among the most effective topical anti-inflammatory treatments for eczema. Some key points to consider when treating eczema include:

  • Topical corticosteroids are a first-line treatment for eczema, with potent and moderate topical corticosteroids being more effective than mild topical corticosteroids, primarily in moderate or severe eczema 2.
  • The effectiveness of topical corticosteroids is similar between once daily and twice daily (or more) frequent use to treat eczema flare-ups 2.
  • Topical corticosteroids weekend (proactive) therapy is probably better than no topical corticosteroids/reactive use to prevent eczema relapse (flare-ups) 2.
  • Phototherapy, including narrowband ultraviolet B (NB-UVB), ultraviolet A1 (UVA1), and psoralen plus ultraviolet A (PUVA), may be used to treat eczema, but the evidence is limited and of low certainty 3. It is essential to consult with a dermatologist before starting any treatment for eczema, especially if considering complementary approaches like RLT, and to continue prescribed eczema treatments while monitoring for any adverse reactions.
