LED Light Therapy Benefits, Procedures, Red Light, Blue Light, Yellow Light

Updated: Sep 12, 2022

LED light therapy is a non-invasive, painless treatment. During treatment, you might feel some warmth but no discomfort.



Are there different kinds of LED light therapy?

LED light therapy uses various wavelengths that correspond to different visible colors. Each color penetrates the skin at different depths.


Blue light affects the uppermost layer of your skin.

Yellow light penetrates deeper.

Red light travels further into your skin.

Near-infrared light penetrates deepest.

Different LED colors do different things. For example, experts believe:


Red LED light therapy may reduce inflammation and stimulate the production of collagen, a protein responsible for younger-looking skin that diminishes with age.

Blue LED light therapy may destroy acne-causing bacteria (P. acnes).

During treatment, skin specialists may use a combination of lights to treat your specific issue.


Red light: Wave length: 620-700nm ( penetrates deepest)

  • anti aging

  • heal old scars

  • stimulate collagen and elastin production which are the building blocks of the skin.

  • reduces inflammation caused by blemishes, sun damage by accelerating the healing process thus improving skin tone and reducing wrinkles.


Yellow LED lights: Wave length: 590–560 nm (penetrates deeper than blue light)

  • triggers the lymphatic system to remove toxins from the exposed area.

  • increases blood circulation which improves wound healing

  • increases the skin’s ability to retain moisture, keeps the skin hydrated and amplifies your skincare regimen.

Blue LED lights: Wave length: 405nm to 420nm (affects the uppermost layer of your skin)

  • Anti-bacterial. This allows it kills off acne-causing bacteria and is most useful during the eruptive phase to address the problem at its source.

How long does it take for LED light therapy to work? What happens during in-office LED light therapy?

To see significant benefits, you typically need to have a series of in-office treatments. You may need a treatment each week for about a month. Then you might need maintenance treatments every month or every few months.


Some at-home devices may also require a substantial time commitment. You might need to use your device twice a day for 30 to 60 minutes for four to five weeks. Other devices take just a few minutes a day.


What happens during in-office LED light therapy?

After putting on your goggles, lie on your back as your healthcare provider places the LED light therapy device above your face. Lie still during the entire treatment as the device works. The treatment usually lasts about 20 minutes.
