There is no scientific evidence to support the use of red light therapy for weight loss, cancer, cellulite removal, or mental health problems such as depression and seasonal affective disorder (SAD). With red light therapy, you expose the skin to a lamp, device, or laser with a red light. A part of cells called mitochondria, sometimes called “energy generators” of cells, absorbs it and produces more energy. Some experts believe that this helps cells repair and be healthier.
This stimulates healing of skin and muscle tissue. Red and blue lights are often promoted in LED skin treatments. Experts believe that red LED light acts on skin cells known as fibroblasts, which play a role in the production of collagen, a protein that makes up a large part of connective tissue and helps the skin recover when damaged. So in theory, red light could help reverse some of the signs related to photoaging in the skin, says Dr.
Additionally, some studies show that red light can help restore hair for people with androgenetic alopecia, or male- female pattern hair loss, she says. Other forms of treatment, such as cold or hot lasers, do not have the same advantages as red light therapy from LEDs. This red light is natural and can penetrate deep into the skin, where cells can absorb and use it. The healing effects of phototherapy are nothing new: it was first used in the late 19th century to treat cutaneous tuberculosis (TB), and NASA used it in the 1980s to grow plants in outer space.
The different wavelengths of the visible light spectrum correspond to different colors of the LED light and penetrate the skin at different depths. Red light therapy can help offset the negative effects of blue light and promote overall well-being and cellular balance. Make sure your professional has credentials and a strong reputation for performing red light therapy. Remember to consult a qualified healthcare professional if you have specific questions about red light therapy.
Scientists discovered that intense light from red light-emitting diodes (LEDs) helped promote plant cell growth and photosynthesis. A controlled trial to determine the effectiveness of red and near-infrared light treatment in patient satisfaction, reduction of fine lines, wrinkles, skin roughness, and increased intradermal collagen density. There are no established guidelines for how long or intensively red light therapy should be applied, so there is a slight chance of adverse effects. Many studies have yielded promising results, but the benefits of red light therapy remain controversial.
RLT is just one part of a complete skincare routine and shouldn't be the only way a person cares for their skin. Red light therapy is a simple, non-invasive treatment that applies red and near infrared (NIR) light to a person's skin and cells. Red light therapy helps soothe and decrease redness, and minimize oil production and bacteria in the skin. A high-quality, medical-grade home red light therapy device, such as a Joovv, uses light-emitting diodes (LEDs) to deliver near-infrared and red light to the body during a treatment session.
