Nowadays, Led light therapy is very popular, but you may not familiar with the led light therapy color meanings, and the different color uses. Well, in this publication, we will introduce the led light therapy color meanings and uses.
What is LED Light Therapy
LED (Light Emitting Diode) phototherapy is a non-invasive treatment that uses different LED wavelengths to enter the skin layers to improve the skin.
Dermatologists and aestheticians commonly use LED light therapy to treat a range of skin problems, including：
- Treating acne
- Reducing inflammation
- Promote anti-aging effects
If you have these types of skin care issues and are not getting the results you want from over-the-counter (OTC) skin products, you may be a candidate for LED light therapy. LED therapy is safe for all skin colors and does not cause any burning.
LED Light Therapy Color Meanings
Different colors of LED light can have different effects on the skin. So, what color LED light we need for our treatment depends on what we want to achieve.
Here’s what the different colors of LED light therapy meanings
Blue light
Blue light is a range of the visible spectrum, defined as wavelengths between 400 and 525 nanometres. This includes the wavelengths between violet and cyan in the spectrum. Narrow-spectrum blue light (also known as blue LED light or short-wavelength LED light) is a high-energy form of visible light, defined as wavelengths between 400 and 450 nanometres. This light is common in LEDs and is also widely used in cosmetic applications.
Red light
Red light is the most common type of light used in led therapy and it has a longer wavelength, allowing it to penetrate the skin more deeply than blue light. Red light stimulates blood flow while stimulating the production of collagen and adenosine triphosphate (ATP), improving skin tone and texture. Infrared and red light work in combination to produce a regenerative effect in aging skin.
Stimulates collagen and elastin within the dermis, increasing blood flow and oxygenation to the skin, while delivering nutrients and antioxidants for repair. Increased protein regeneration makes skin look and feel plumper and brighter, and the density of the dermis is increased to fight the aging process.
Near infrared light
Penetrating deep into the skin, it can reach the bones, increasing cellular activity and making our cells behave more responsively. Increases production of collagen, elastin, and hyaluronic acid to maintain skin’s structure and make it look younger.
Near-infrared also reduces inflammation and pain by increasing blood flow and tissue oxygenation, supporting cellular health and repairing damage. In terms of skin tone, it regulates melanin production and increases antioxidants and nutrients within the skin. It also balances hormones like cortisol (the stress hormone), serotonin (the feel-good hormone), and melatonin (our sleep hormone).
LED Light Therapy Color Uses
Red LED light therapy reduces inflammation and stimulates the production of collagen, a protein responsible for young skin that decreases with age. Therefore, red LED light therapy can be used mainly for the treatment of blemishes, freckles, pigmentation etc.
Blue light (425 nm) has an anti-inflammatory effect on the skin, shortens healing time, and also prevents scarring after inflammation. Blue light targets and destroys acne bacteria in the sebaceous glands, thus reducing bacteria and the formation of spots or pustules. It also regulates oil production, balances oily skin or the T-zone and increases blood circulation, helping to eliminate toxins and nourish the skin.
Blue LED light therapy destroys the bacteria that cause acne (Propionibacterium acnes). Therefore, blue led light therapy can be used mainly for acne, folliculitis, rosacea, etc.
Does LED light therapy actually work?
There are studies that prove that LED light therapy can help reduce and improve some skin conditions and problems. However, it takes regular treatments to see real improvements in the skin to make a difference.
