Photobiomodulation Therapy for Diabetic Wound Healing
Quick fact
Photobiomodulation was accidentally discovered in the 1960s, and today, specific wavelengths like 660 nm (red) and 810 nm (near-infrared) are used to stimulate tissue repair.
Why this is interesting
Imagine a small handheld light, not a surgery, that could help stubborn diabetic wounds finally close. How can shining red light on the skin actually speed up healing?
