LED light therapy is a popular non-invasive skin treatment for acne, sun damage, wounds, and other skin problems. People can choose to have LED light therapy at a dermatologist’s office or to use a device at home. The treatment uses varying wavelengths of light to trigger the skin's natural healing processes to repair skin. Several treatments are necessary to see results.

In this article, we explore how LED light therapy works and who might be a good candidate. We also cover the possible side effects.

What is it?

Due to a lack of UV rays, it is safe to undergo LED therapy regularly.

LED stands for light-emitting diode. These lights have been in use since the 1960s, but people have only recently begun to use them as a skin treatment.

NASA originally developed LED lights for plant growth experiments in space. However, since then, LEDs have shown promising results in wound healing and human tissue growth.

Different wavelengths of light in LED lights, including blue and red, penetrate the skin at different depths. This penetration may trigger biological processes that help the skin rejuvenate and heal.

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 research 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 this 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.

One of the main benefits of LED light therapy is its safety record. According to research, LED light therapy has an excellent safety profile.

It does not contain UV rays, which can be harmful to the skin. Therefore, LED therapy is suitable for regular use.

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.

Does it work?

Research indicates that LED light therapy can be effective for wound healing and other types of skin damage.

In the past, Navy SEALs used LED light therapy to help heal wounds. The treatment led to improvements of more than 40% in musculoskeletal injuries in team members. It also reduced wound healing time.

When it comes to cosmetic procedures, a review of several studies indicates that LED light therapy devices can improve a range of skin conditions, including psoriasis and mild-to-moderate acne.

According to the American Academy of Dermatology, most people with acne will see an improvement in their symptoms from using LED light therapy, but they should not expect all acne to clear.

It is necessary to have several treatment sessions before noticing an improvement in skin appearance. People usually see the best results several weeks after their last treatment.It may also be necessary to have follow-up sessions to maintain these results.
