Red light therapy (RLT) is a type of treatment that uses red and near-infrared light to improve the overall health of the skin. This therapy is often used to treat conditions like wrinkles, acne, scars, and dark spots and the overall appearance of your skin, but with the additional of near infrared it can also provide whole-body healing benefits as well. Red light therapy is becoming increasingly popular as more people are looking for alternative treatments for both their skin problems, anti-aging effects and chronic illnesses… or even just for optimizing wellness and vitality!
Red light therapy is a visible wavelength of 630-660 nanometers, with near infrared in the 800-990 nanometer parameters. This penetration boosts collagen production which leads to firmer, smoother skin with fewer wrinkles and fine lines. Red light therapy is often used in conjunction with other treatments like micro needling or chemical peels to maximize results.
Here are some of the other skin-related benefits:
- Reduces wrinkles and fine lines: Have you heard of using lasers to reduce the appearance of fine lines and wrinkles? What about red light therapy? A growing body of evidence suggests that red light therapy can be an effective way to reduce the appearance of fine lines and wrinkles, with few, to no side effects. Here's a look at how it works.
Red light therapy is a type of phototherapy that uses low-level wavelengths of red or near-infrared light to stimulate skin cells and promote healing. Studies have shown that red light therapy can increase collagen production, improve blood circulation, and reduce inflammation. All of these effects can help to reduce the appearance of fine lines and wrinkles.
This study looked at the effects of RLT on 136 volunteers who had significant sun damage. The women were divided into two groups, with one group receiving eight weeks of twice-weekly treatments with a red light device, and the other group receiving no treatment. At the end of the study, the researchers found that the treated group had significantly less wrinkles than the untreated group, with less skin roughness.
Additionally, LED (Light-Emitting Diode) therapy has proven improved skin tone with 91% of subjects in a 12-week followup, according to a study in The Journal of Cosmetic Dermatology.
2. Stimulates collagen production: Collagen is a protein found in the connective tissue of our bodies, including skin, joints, bones, and tendons. It's what gives our skin its elasticity and strength. Unfortunately, as we age, our bodies produce less and less collagen. This loss of collagen leads to wrinkles, sagging skin, and a loss of firmness.
The light in red light therapy stimulates collagen production and helps to speed up cell turnover. Red light therapy works by penetrating deep into the skin to stimulate collagen production. This process is known as "photobiomodulation," which can modulate inflammatory cells.
When our bodies are exposed to certain wavelengths of light, it causes a chain reaction that leads to increased collagen production. But not all wavelengths of light are equal when it comes to photobiomodulation. Studies have shown that red and near-infrared light are the most effective for stimulating collagen production.
One study found LED treatments would increase collagen 31% more in treated vs. non-LED treated individuals, as evaluated on a tissue-engineered Human Reconstructed Skin model.
Other studies have shown similar results. A study published in 2014 found that red light therapy can increase intradermal collagen density and reduce fine lines and wrinkles.
One of the best things about RLT is that it's completely safe and has no negative side effects. Unlike some other skin care treatments, there's no risk of sun damage with red light therapy. You can use it as often as you like without fear of damaging your skin. In fact, many people find that their skin looks and feels healthier after just a few sessions of red light therapy!
