What is LED light therapy? Light-emitting diode (LED) light is a technology that emits different wavelengths of light, which also includes light colors, on a visible light spectrum, according to board-certified dermatologist Dr. Reshimi Kapoor. She also explains the wavelengths can reach deep into layers of the skin. "Different wavelengths penetrate the skin at different depths and have varying biological effects on the skin depending on the depth of penetration," says Kapoor.

In the 90s, NASA began exploring the benefits of LED light therapy when it came to wound healing and since then, it has become a staple at many dermatology clinics and aesthetic spas.

What are the benefits of LED light therapy for skin? So what can you expect? Dr. Angela Lamb, a board-certified dermatologist, says this type of light therapy can provide skin benefits for a variety of goals, based on your area of concern. And while you might see a variety of lights, our experts says red and blue light therapy are most commonly used to help with the skin.

According to the Mayo Clinic , blue light targets the uppermost layer of skin, yellow light goes deeper and red light goes further in depth which is why it's a favorite for stimulating collagen. Read on to see more benefits of these lights.

Red light therapy

Fine lines and wrinkles

Collagen boost

Hair loss

"Red LED light has been shown to stimulate the fibroblast, a cell that plays a role in collagen production, which could help reduce signs of photoaging and improve fine lines and wrinkles ," says Kapoor. "Red light may also play a role in wound healing, decreasing inflammation and improving hair loss."

Blue light therapy

Acne and acne causing bacteria

Oil reduction

If you suffer from acne , blue light might be for you. Both dermatologists say this color targets acne by reducing oil production in the sebaceous glands and targeting acne-causing bacteria.

Other LED light colors

: Brightening

: Redness

While red and blue are the most common LED lights for skin, there are other options out there. Some devices even offer a mode that mixes blue and red, which will target fine lines and acne. However, Kapoor notes that while there is less evidence, green light can help with brightening the skin complexion and yellow light may help combat redness .
