Is it possible to use red and blue light therapy for herpes zoster?

It is acceptable to use red and blue light irradiation for the treatment of herpes zoster. Herpes zoster is an infectious disease caused by the varicella-zoster virus infection, and typically presents with symptoms such as rash and pain. Red and blue light irradiation therapy for herpes zoster mainly utilizes high-frequency light sources to irradiate the skin, which can promote the resolution of rashes, relieve symptoms of skin itching and pain, and has antibacterial effects, helping to eliminate localized virus particles and promote disease recovery. However, using red and blue light irradiation alone may not achieve a complete cure. It is usually necessary to combine it with antiviral medications, such as acyclovir cream, for treatment. In addition, patients should maintain local cleanliness and care during treatment, avoid contact with irritating substances, and keep the skin dry and clean to promote recovery.
