LED stands for Light Emitting Diode, which is a computer chip encased in a glass-like resin, which emits therapeutic wavelengths (or colours) of light energy.
Not to be confused with laser, the light therapy was originally developed to fast-track the healing of wounds and post surgery scars. The rejuvenation of healthy skin, too, was a happy coincidence.
LED is great for reducing the appearance of fine lines and wrinkles, improving uneven skin tone, reducing pores size, brightening the skin and rejuvenating the youthful look of your skin.
Light Therapy is also used to enhance other therapies such as microdermabrasion or peels and enhance the effects of botox and fillers.
