Red light therapy and blue light therapy are two types of phototherapy, or light therapy, that have been used for various medical and cosmetic purposes. Both types of light therapy use specific wavelengths of light to target specific cells and tissues in the body, and they have been shown to be effective in treating a range of conditions. In this article, we will explore what red light therapy and blue light therapy are, how they work, and what they are used to treat.
Red Light Therapy
Red light therapy uses wavelengths of red light to stimulate the cells in the body. The wavelengths of red light used in red light therapy are typically in the range of 630 to 660 nanometers. Red light therapy has been shown to be effective in reducing inflammation, improving circulation, and stimulating the production of collagen and elastin, which are proteins that are essential for healthy skin. Red light therapy has been used to treat a range of conditions, including acne, rosacea, eczema, and psoriasis. It has also been used to reduce the appearance of scars and stretch marks, and to improve the overall appearance and texture of the skin.
Blue Light Therapy
Blue light therapy uses wavelengths of blue light to kill bacteria and reduce inflammation. The wavelengths of blue light used in blue light therapy are typically in the range of 400 to 420 nanometers. Studies have found that blue light therapy can eradicate acne-causing bacteria, decrease inflammation, and enhance the look of your skin. It has been employed to treat an array of skin issues such as acne, rosacea, and eczema.
Differences Between Red & Blue Light Therapy
One of the main differences between red light therapy and blue light therapy is the wavelength of light that is used. Red light therapy uses longer wavelengths of light, which are absorbed by the deeper layers of the skin, while blue light therapy uses shorter wavelengths of light, which are absorbed by the surface layers of the skin. This means that red light therapy is more effective at stimulating the cells and tissues in the deeper layers of the skin, while blue light therapy is more effective at killing bacteria and reducing inflammation on the surface of the skin.
Another difference between red light therapy and blue light therapy is the type of conditions that they are used to treat. Red light therapy is primarily used to treat skin conditions and improve the overall appearance of the skin, while blue light therapy is primarily used to treat acne and other skin conditions that are caused by bacteria.
In terms of effectiveness, both red light therapy and blue light therapy have been shown to be effective in treating a range of conditions. However, the specific results and benefits of each type of light therapy can vary depending on the individual, the condition being treated, and the specific treatment protocol used. It is important to consult with a healthcare professional before starting any new treatment, including light therapy, to ensure that it is safe and appropriate for your specific needs.
You can buy at-home light therapy devices. Several companies specialize in making red light and blue light therapy wands. Make sure to consult a dermatologist in order to determine if light therapy is an appropriate treatment for you.
