The use of light as medicine may be making its way back into the skincare scene, but it has been around for—well,  ever. “The sun is your best medicine” isn’t just a popular saying, it’s true. The “invention” of concentrated light medicine in the medical world dates back as early as 1895 when it was first utilized by Niels Ryberg Finsen to treat lupus vulgaris. What happened? The treatment was soon replaced with antibiotics, much like today’s light medicine alternatives being swapped for pharmaceutical drugs. The good news is doctors and their patients are seeing the pros to using an all natural treatment that isn’t a “trend”-enter light medicine back onto the scene.

There are five major types of light medicine that are utilized for several different ailments. The various wavelengths have specific chemical reactions within the body’s cells that allow them to treat a wide array of conditions ranging from pain management and wound healing to acne and anti-aging. Below are the most popular uses of light medicine and what they can offer the world of medicine.
