Is red light therapy scientifically proven?

There is no scientific evidence to support the use of red light therapy to lose weight, cancer, eliminate cellulite, or mental health problems, such as depression and seasonal affective disorder (SAD). The main objective of the study was the improvement of subjective skin complexion and skin feel. Volunteers were asked to specify their level according to the statements in the questionnaire by marking a position along a solid black line between two endpoints measuring 10 cm, which served as a visual analog scale (VAS). The secondary objectives were the improvement of measurement parameters using a DermaLab Combo (Cortex Technology, Hadsund, Denmark), a computer-supported skin diagnostic system equipped with a high resolution (20 MHz) rotating ultrasound sensor probe for the determination of changes in collagen intradermal density, measured as collagen intensity score (CIS).

A Primoslite digital fringe projection system (GFM Messtechnik, Berlin, Germany) was used to measure the objective arithmetic roughness (Ra) of the skin surface in the periorbital region. Some authors emphasize the importance of different wavelengths for optimal results, 16—18.26—28 In our study, the differences between RLT and ELT treatments in clinical outcome and patient satisfaction were not significant, indicating that, despite spectral differences, both light sources were proportional. effective with respect to the objectives of the study. Additional studies of treatment parameters are needed.

Although there is early research into RLT, there is still no conclusive evidence that it is a beneficial treatment. Many studies show that treatment is promising, but more extensive clinical studies in humans will help determine possible applications of RLT. 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. In addition, some studies show that red light can help restore hair for people with androgenetic alopecia or male and female pattern hair loss, he says. Aging, disease, or lifestyle factors can cause mitochondria to produce less ATP. red light therapy triggers a reaction that helps reverse this decline.

Red light therapy is a non-invasive treatment that uses red or near infrared light to help heal muscles, skin, or other parts of the body. We talked to dermatologist Rhonda Klein, MD, about the claims of red light therapy and how she uses red light therapy in her practice. Often, blue and red light are used in combination to help fight acne, blue light is directed at C. But does red light therapy really work? Over the past two decades, thousands of published studies have focused on red light therapy.

Red light beds found in salons are said to help reduce cosmetic skin problems, such as stretch marks and wrinkles. No matter what type of traffic light you're treated with, exact wavelength matters; you can't just sit under a red light for half an hour and wait for results (except maybe a traffic ticket). Relationship between dose and wavelength ranges for ELT and RLT light sources, normalized to spectral range 611—650 nm. The combined use of red and NIR light allows you to experience the unique benefits of each wavelength.

We investigated the safety and efficacy of a new non-thermal, non-ablative, atraumatic and polychromatic low-level polychromatic light treatment modality with a focus on pleasant skin feel, improved skin appearance, increased intradermal collagen, and visible reduction of fine lines and wrinkles in the future. randomized controlled trial involving 136 volunteers. Laser and pulsed light therapies work by causing controlled damage to the outer layer of skin, which then induces tissue repair. The Los Angeles Times also reports that, under the right conditions, red light therapy can reduce inflammation, potentially allowing tissues to heal faster than they would in the absence of treatment.

NIR light is particularly effective at penetrating deep into muscle and connective tissue to stimulate healthy tissue growth (by increasing cellular energy), increasing blood flow and reducing inflammation. Some light therapies also use blue lights or full spectrum lights, but different wavelengths of light have different effects. Red light stimulates mitochondria (the energy centers of muscle cells) to produce more energy, leading to faster cell regeneration and growth. In addition, the soothing warmth of red light treatments can offer an immediate sense of well-being, contributing to a decrease in pain perception.

A small study published in the Journal of Cosmetic and Laser Therapy explored the effect of low-level light on people with alopecia. . .
