Red and blue LED light can make a significant impact on your quest for complexion perfection.
For some people, using light emitting diodes (LEDs) to treat things like acne and aging may sound too good to be true. How can it be that shining coloured lights on your face will clear up zits and make your skin look plump and youthful? Well, the science is in the stars. About 40 years ago, scientists at NASA discovered that light therapy could repair damaged skin cells and speed up healing.
Over recent years we’ve seen great results when using light to treat a variety of common skin conditions. The technical term is LED photomodulation, and it works in a similar way to photosynthesis by triggering the body to convert light energy into cell energy, encouraging natural cellular activity and ‘re-energising’ skin cells.
We focus on the most researched and effective light waves: red and blue.
Red for Wrinkles
Red infrared light therapy uses visible red light wavelengths from 630-660 nanometres (nm) and infrared light wavelengths at around 880nm to penetrate deep into the layers of the skin, increasing cellular energy and jump-starting the production of collagen and elastin to help make skin firm and supple.
The layers of the skin have a high content of blood and water, which makes it easy for the skin to absorb the light, these substances literally drink it up. Most researchers agree that light therapy increases production of adenosine triphosphate (ATP), the battery life of cells. It also targets the water layers in elastin — the protein responsible for skin elasticity – gradually restoring its elastic function and reducing the appearance of facial wrinkles.
Red light also boosts blood circulation, which effectively transports oxygen and nutrients to the skin (hello glow!), and it’s a great healing treatment for rosacea and eczema too.
Blue for Blemishes
Blue Infrared light has a wavelength of 400–490 nm and is especially good for treating acne. When blue light reaches the sebaceous glands in the skin, it can help activate porphyrins, which are compounds inside acne bacteria (technically called propionibacterium acnes). When porphyrins are activated, they release reactive oxygen molecules that damage the bacteria internally, killing it from the inside out. And because red light helps accelerate wound repair, it’s often used in combination with blue light to treat acne, encourage healing, and lessen acne scarring and under the skin lesions.
Who’d have thought it? Red and blue light can effectively and gently create significant changes in the skin at a deep level encouraging the complexion perfection you long for.
