What is red light Therapy？

Red light therapy (RLT) is a therapeutic technique that uses low level wavelengths of red light to help treat skin conditions, such as wrinkles and psoriasis. Though the treatment seems promising, more research is needed.

Red light therapy (RLT) is a type of phototherapy that may help:

• treat skin issues, like stretch marks and wrinkles
• treat skin conditions, such as psoriasis, scars, and acne
• reduce inflammation or edema
• repair muscle tissues
• promote healthy aging

RLT is commonly referred to as photobiomodulation. It was accidentally discoveredTrusted Source by Endre Mester in 1967 at the Semmelweis Medical University in Budapest, Hungary. He noticed that laser light helped promote hair growth and wound healing in rats.

Scientific literature suggests there are nearly 60 other namesTrusted Source for RLT, such as:

• low level light therapy (LLLT)
• soft laser therapy
• cold laser therapy
• biostimulation
• photonic stimulation
• low power laser therapy (LPLT)

In the 1990s, light-emitting diode (LED) technology was used by scientists to help grow potatoes in space. The intense red LEDs helped promote photosynthesis. Supposedly, it also helped wounds on the scientists’ hands heal faster.

Red light was then studied for its potential medicinal application during space travel. Researchers hoped it would help treat the muscle atrophy, slow wound healing, and bone density issues caused by weightlessness in space.

Although RLT is gaining traction as a dermatological treatment for certain conditions, more clinical research is needed to fully support its claimed benefits.
