Can red light therapy help with prurigo nodularis scarring, loss of pigmentation, and white spots?
Red light therapy isn't something that comes up specifically in the current research on prurigo nodularis. The light-based treatment that has been studied for PN is phototherapy, which uses controlled UVB rays in a clinical setting.
When PN nodules heal, they can leave behind:
- Scarring
- Skin discoloration (lighter or darker patches)
- Raised areas even after the nodule is gone
These changes happen because new collagen tissue forms over the healed wound, which can affect how the skin looks and its pigmentation. The most important thing to know is that any UV or light-based treatment — including red light therapy — should be discussed with a dermatologist before trying it. Unsupervised light exposure carries risks, including skin damage.
A dermatologist experienced in PN would be the best person to advise on whether red light therapy is appropriate for your specific skin concerns, and whether it could complement your existing treatment plan.
