What are people's experiences with red light therapy as a treatment for prurigo nodularis?
Red light therapy specifically isn't well-documented as a PN treatment in current research. The light-based therapy most studied for PN is phototherapy, which uses UVB (ultraviolet B) rays rather than red light.
Here's what's known about phototherapy for PN:
- It can help ease intense itching
- It may be especially useful when topical treatments aren't working
- It tends to work best when large areas of the body are affected
- It requires visits to a clinic 2–3 times per week
- Results can take 6–8 weeks to appear, and relief may be incomplete
It's worth noting that tanning beds and natural sunlight are not safe substitutes — they emit mostly UVA rays and carry real risks like skin cancer. Supervised phototherapy in a clinical setting is the safer route.
Since red light therapy falls outside what's currently documented for PN, it's best to have an open conversation with your dermatologist before trying it. They can help weigh any potential benefits against risks for your specific situation.
