LED red light therapy is a broad term that encompasses various wavelengths – or colors – of LED to stimulate a cellular response in the skin. The most popular and well-researched forms of red light for anti-aging benefits are red, amber, and infrared light. When used together, these wavelengths help to reduce the appearance of lines and wrinkles, enhance skin radiance, and promote overall skin vitality.

Red light facial devices use light-emitting diodes (LED) to emit wavelengths – various colors of light – to the skin. Once light photons are absorbed by cell components, they stimulate a biochemical response in the skin. Different forms of red light – like amber, red, and infrared – produce different reactions in the skin to address your unique skin needs.

Red light therapy is well-researched and is considered safe when used appropriately. Professionals often recommend LED red light therapy because it is safe, non-invasive, and painless. Unlike other forms of light therapy, red light therapy does not expose skin to ultraviolet (UV) wavelengths, which causes skin damage. Be sure to look for FDA-Cleared facial devices, which have been rigorously tested to ensure they are safe and effective.
