Red Light Therapy: What Is It and How Does It Work?
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 conditions, inflammation, muscle pain, and other conditions.
Red light therapy uses light-emitting diode (LED) technology and various wavelengths of light. Some people report that using these lights improves various conditions, but more research is needed to confirm these results.
Benefits:
- Treat skin changes like scars, stretch marks, and wrinkles
- Treat skin conditions such as psoriasis and acne
- Reduce inflammation or edema
- Repair muscle tissues
- Promote healthy ageing
Endre Mester discovered it in 1967. He noticed that laser light helped promote hair growth and wound healing in rats.
In the 1990s, scientists used light-emitting diode (LED) technology to grow potatoes in space. The intense red LEDs helped promote photosynthesis, and the scientists reported that their hands healed faster.
Red light was then studied for its potential medicinal application during space travel. Researchers hoped it would help treat 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.
