Red Light Therapy (RLT) is another term for what is widely known as Low Level Laser Therapy (LLLT), LED Therapy or Cold Laser Therapy. It is a non-invasive, painless treatment used for healing many medical conditions, including skin rejuvenation. Red Light Therapy (RLT) also comes under the broad category of Therapeutic Laser known as Photobiomodulation Therapy (PBMT) or Photo Medicine. Red Light Therapy (RLT) is associated with many home use LLLt devices to improve skin and to manage chronic pain.
Red Light Therapy (RLT) references the light wavelengths used, which are within the Infra Red / IR (600-700 nm) and Near Infrared / NIR (780-1100 nm) wavelength range. Visible light ranges, while beneficial, are limited by their shallow penetration of 1-3 mm , which is perfect for treating skin conditions including acne and signs of ageing. Invisible or NIR light wavelengths penetrate much deeper, clinical results indicate up to 10 cm. The therapeutic process enables light to carry electrons throughout the body to restore damaged cells, address problems that arise from damage cells, and to provide pain relief.
Class 1 devices cannot harm the eyes, which is why they are freely available for home use. Power output for Red Light Therapy | LED equipment is usually can increase up 500 mW to fall within a low power laser category. We recommend a number of Class 1 home use laser devices for our patients to use in between treatments in the clinic, including the Handy Cure Laser and the B Cure Laser.
Some Red Light Therapy | LED products on the market have increased the power output. Class 2 lasers are limited to a maximum output power of 1 milliwatt or one-thousandth of a watt (abbreviated to mW). The NovoThor Red Light Therapy bed is a good example.
Class 3b Laser is widely used within most clinical Low Level Laser equipment used by the medical profession in the area of Photobiomodulation (PMBT). Class 3b Laser does not create a thermal effect so it does not burn, however Class 3b laser could damage the eyes if shone directly into them. Protective goggles are always worn and the treatment is administered by a professionally trained therapist.
Class 3b Laser is considered the most effective Red Light Therapy available and is employed for healing and pain relief, clinical trials and research in the Laser Therapy field. At Laser Medicine we use a variety of probes with different wavelengths and power output depending on the specific medical condition or type of treatment. Skin, as mentioned earlier, requires a different approach to, for example, bone fracture repair.
Laser devices with an output power of above 500 mW can burn the skin. This kind of Laser should not be used for Low Level Laser | Photobiomodulation Therapy and is misleading if this is the manufacturer’s claim. Class 4 Lasers are typically used for procedures that create an ablative or thermal response in the skin such as hair removal tattoo removal.
