LED, or Light Emitting Diode therapy..

is a skincare treatment that uses varying wavelengths of light, including red and blue. NASA originally developed it for plant growth experiments on shuttle missions and later found it to have promise for wound treatment.

LED light therapy is now used by some aestheticians to help regenerate the skin from aging. It’s also used for acne.

Different colours of light therapy are used for different skin types/problems for example red is primarily used for anti-aging, while blue is used for acne treatment.
