(LED) light therapy is growing in popularity in both aesthetician offices and at home. Using varying LED wavelengths, this skincare technique purportedly helps:

Treat acne

Reduce inflammation

Promote anti-aging effects

You may be a candidate for LED light therapy if you have these types of skincare concerns and haven’t gotten the results you want from over-the-counter (OTC) skin products. LED therapy is also safe for all skin colors, and it doesn’t cause any burning.

LED lights have only recently been used as a skin treatment. Different wavelengths of the visible light spectrum correspond to different colors of LED light and penetrate the skin to different depths. Depending on how deeply they penetrate, LED lights are thought to have different biological effects.

Red and blue lights are typically promoted in LED skin treatments. Experts believe that red LED light acts on cells in the skin known as fibroblasts, which play a role in production of collagen, a protein that makes up a large part of connective tissue and helps the skin to recover when it's harmed. So, in theory, red light could help to reverse some of the signs related to photoaging in the skin. In addition, some studies show that red light may help to restore hair for those with androgenetic alopecia, or male- and female-pattern hair loss.

Blue light:

Experts believe that blue LED light reduces activity in the sebaceous glands, which are small oil-producing glands in the skin. This reduction in activity causes the glands to produce less oil, possibly improving acne symptoms.Blue light may also kill a type of bacteria that contributes to acne by causing inflammation. Animal researchTrusted Source indicates that blue light can improve the healing of third degree burns.

Red light:

Red LED light may improve scarring and signs of aging, such as wrinkles. It may do thisTrusted Source by acting on fibroblasts, which are skin cells that are responsible for collagen production. Collagen is a protein in the skin and other connective tissues. It plays a role in skin healing. The body produces less collagen as a person ages, which causes the skin to show signs of aging. Red light also reduces skin inflammation.

LED light therapy can help treat a variety of skin problems, including:

  1. scarring
  2. signs of aging, including wrinkles and age spots
  3. sun damage
  4. other inflammatory skin conditions
  5. acne
  6. wound healing
  7. dull skin
  8. eczema
  9. psoriasis
  10. rosacea

LED light therapy is noninvasive, so no recovery time is required. You should be able to continue with your everyday activities once your treatment is over. Unlike chemical peels or laser therapy, LED light therapy does not cause burns. The treatment is also safe for all types and colors of skin.  In-office LED light therapy requires up to 10 sessions or more, each spaced out about a week apart. You may start to see minor results after your first session. Results will be more dramatic and noticeable once you’ve finished all of your treatments. Even after you’ve achieved the recommended number of sessions, your results aren’t permanent.

As your skin cells turn over, you may lose some collagen and start to see signs of aging again. You may also start to see acne breakouts. This is why it’s recommended that you go back for maintenance treatments every few months or as recommended by your provider.

LED light therapy is suitable for use on any body part, including the face, hands, neck, and chest. Following treatment, no recovery time is necessary.
