What is blue light?
Blue light is defined as light within the wavelength range of 400-480 nm. This is because over 88% of the risk of photo-oxidative damage to the retina from fluorescent lamps (cool white or “broad spectrum”) is due to light wavelengths in the range of 400-480 nm. The blue light hazard is at its highest at 440 nm, and it drops to 80% of its highest point at 460 and 415 nm. On the other hand, green light at 500 nm is much less harmful to the retina than blue light at 440 nm.
What does blue light therapy do for the body?
Blue light therapy uses light with specific wavelengths, ranging from 400 to 500 nanometers. It treats a variety of skin conditions with a light therapy device that emits blue light.
Some cells in the body are very sensitive to blue light. This includes some types of bacteria, like the ones that cause acne, and even cancer cells.
Blue light is very short, so it doesn’t go deep into the skin, which makes it very useful for treating acne, inflammation, and other skin conditions.
Blue light therapy is also very effective when used with red light therapy.
Merican Blue Light Therapy: 480 nm wavelengthBlue light therapy is one type of light therapy that is quickly becoming well-known for some of its amazing benefits, especially when used with red and NIR light therapy.
It can repair sun damage and help treat precancerous lesions.Blue light used with a photosensitising agent has been found to be effective in treating actinic keratoses or precancerous lesions caused by sun damage. Treating an individual actinic keratosis lesion can prevent skin cancer. This treatment only targets diseased cells, with minimal effect on the surrounding tissue.
Mild to moderate acneBlue light treatment is now a popular skincare option for mild to moderate acne. The bacteria that cause acne (Propionibacterium acnes) are sensitive to light.
