What Is Red Light Therapy And How Does It Works?

Red light therapy is a type of phototherapy that uses low-level red light to treat various skin conditions and improve overall skin appearance. Red light therapy works by penetrating the skin and increasing blood circulation. It helps to improve cellular metabolism and promotes the production of collagen and elastin.

In addition, red light therapy can also help to speed up the healing process following surgery or injury. While there is no cure for aging, red light therapy can help to reduce the visible signs of aging. It also improves overall skin health. It’s sometimes also called photobiomodulation therapy or low-level light therapy. During red light therapy, a device emits near-infrared light waves that pass through the skin and into the body.

Once these light waves reach deep tissue, they promote healing by stimulating cell production and increasing blood flow. Red light therapy is often used to improve the appearance of the skin, reduce inflammation, and relieve pain. However, it may also help to speed up wound healing, reduce the side effects of chemotherapy, and ease muscle soreness.
