LED Light Therapy
What is LED light therapy?
LED light therapy is a popular noninvasive skin treatment for acne, sun damage, wounds, and other skin problems. The treatment uses varying wavelengths of light to trigger the skin’s natural healing processes to repair the skin. Several treatments are necessary to see results. 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. 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 LED 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. Research indicates that blue light can improve the healing of third degree burns.
Red LED Light
Red LED light may improve scarring and signs of aging, such as wrinkles, 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
Uses and Benefits of LED therapy...
LED light therapy can help treat a variety of skin problems including acne, dermatitis, dull skin, eczema, psoriasis, rosacea, scarring, signs of aging, including wrinkles and age spots, sun damage, wound healing, and other inflammatory skin conditions
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.
Safety and Side Effects
In general, LED light therapy is safe. The procedure is noninvasive and does not cause burning or pain. However, experts caution that the long-term effects of these devices remain unknown. Short-term side effects are rare. When they do occur, they may include inflammation, rashes, skin redness or tenderness. Individuals should not use LED therapy if they take certain medications, such as isotretinoin (Accutane), for acne or use topical treatments that cause sensitivity to sunlight. People with skin conditions should speak to a dermatologist before using LED light therapy.
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.
Home devices are usually less effective than professional treatments.
