Led therapy

LED therapy has grown in popularity in the past few years. It promises to fight acne and signs of aging with the use of light technology. And travelers can find it more easily than ever at resort spas where clients want , not just pampering skin care treatments. You may have heard it referred to as blue light, red light, Omnilux or maybe Lite Luxe.

LED Skin Treatment Information and Tips.

While Omnilux and Lite Luxe are actual brand names and red or blue light refers to the type of treatment (red is great for lines and wrinkles while blue is used to treat acne), essentially these are all forms of LED light .

Can LED lights really lead to better skin?

An LED facial, aka Color Light Therapy , uses four clinically proven wavelengths of UV-free LED lights that claims to boost collagen production and treat existing acne. Sounds miraculous, but it could also be too good to be true. FEMAIL writer Unity Blott tested out the £LED blue light therapy treatment loved by everyone from Kourtney Kardashian to Jessica Alba to see if it could rid her of breakouts for good.

How do they compare to other sources of light? Discover the facts about them here.

Suffice it to say, that so far, all the pigments identified in green plants absorb light wavelengths in the UV , blue, red and far-red regions of the light spectrum while ignoring (or avoiding!) the green and yellow regions.

A grow light or plant light is an artificial light source, generally an electric light, designed to stimulate plant growth by emitting an electromagnetic spectrum appropriate for photosynthesis.

Grow lights are used in applications where there is either no naturally occurring light, or where supplemental light is required.
