LED light therapy is a fast-growing technology used to treat a multitude of dermatological conditions in a safe and non-invasive manner.
The effects of LED light technology were first discovered by NASA in the 1980s when they successfully grew plants in space using red LED light to influence the growth of cells.
They later applied this technology to treat muscle and bone atrophy in astronauts. Since then, researchers have been studying the benefits of various wavelengths (colors) of light in everyday life such as cosmetic, clinical and holistic applications to improve our health, sports performance and how we look and feel.

Tell me more about LEDs!
A light-emitting diode (LED) is a semiconductor light source. When an LED is switched on, its moving electrons release energy in the form of photons. A photon is characterized by wavelength, and each wavelength corresponds to a particular color of light.
Each light color penetrates the skin tissue at a certain depth, with longer wavelengths penetrating deeper. Different cells and tissues absorb light at different wavelengths, which is why each light color affects the skin differently.
- Red light aids in anti-aging & anti-inflammation
- Green light helps to calm skin & lightens pigmentation
- Blue light fights acne & stabilizes oil production
