What is Led Light Therapy?

LED Technology is based on semiconductor technology, there is a significant difference between lasers and LEDs is the way the light energy is delivered [optical power output (OPD)]. The peak power output of LEDs is measured in milliwatts, whereas that of lasers is measured in watts. LEDs provide a gentler delivery of the same wavelengths of light compared to lasers and at a substantially lower energy output. LEDs do not deliver enough power to damage tissues and do not have the same risk of accidental eye damage that lasers do.

In short: LED devices use color light therapy (UV-free - UV wavelengths are below 400nm) in specific wavelengths via tiny LED bulbs to increase blood circulation and promote collagen production, skin healing and acne reduction.

In the same way that plants use chlorophyll to convert sunlight into plant tissue, LEDs can trigger natural intracellular photo-biochemical reactions. Light is measured in wavelengths and is expressed in units of nanometers (nm). Different wavelengths have different chromophores and can have various effects on tissue. Wavelengths are often referred to using their associated color and include:

Blue (400-470 nm)
Green (470-550 nm)
Red (630-700 nm)
NIR (Near Infra Red) (700-1200) lights
