What ls Red Light Therapy? Everything You Need to Know

“If you clicked on this link, you may be asking yourself, ‘This looks cool, I’ve seen it everywhere on social media, but does red light therapy really work?’ The answer is yes, it does work – but with a caveat. However, before we go into detail about this red light that claims to cure everything (and arguably cures everything), let’s talk about what it is and why it works on our skin all over.

What is red light therapy?

“Red light therapy is a treatment method that exposes the skin to low levels of red or near-infrared light (most devices use light with wavelengths ranging from 630 to 700 nm),” said Dr. Blair Murphy Rose, a dermatologist certified by the committee. “Red light has been proven to reduce skin inflammation, stimulate fibroblasts’ production of collagen, thereby reducing and preventing wrinkles and improving skin texture.”

Dr. Whitney Bowe, a dermatologist from New York, said, “Unlike ultraviolet rays associated with skin cancer, premature aging, and accelerated aging, LED light is a visible spectrum of light that can benefit the skin. The longer the wavelength (i.e. red light), the deeper the penetration into the skin. Red LED light induces skin changes through a process called photobiomodulation, which does not require injury or trauma.”

The therapeutic benefits of this treatment were first noticed in the late 1980s, and NASA unexpectedly further proposed this hypothesis to some extent. (Scientists from NASA work under red and blue LED lights to simulate the photosynthesis of potato growth, and they point out that wound healing, i.e. hand wounds and abrasions, seems to occur faster.)

Nowadays, red light therapy is a common treatment method in both medical spa centers and living rooms. Bowe said, “LED therapy is used in the office together with other complementary therapies such as microneedles, chemical peeling, or laser therapy.”. “This is a non-invasive treatment that does not require any heat.”


What are the benefits of red light therapy?

Murphy Rose pointed out that frequent use of red light therapy can reduce inflammation, increase collagen production and density, and over time, improve skin texture and reduce wrinkles. This therapy is also used to treat pattern hair loss and hair loss, as well as to reduce body fat.

Bao said, “Red light therapy is believed to promote collagen synthesis in the dermis of the skin and help alleviate skin inflammation.”. The interaction between light and skin stimulates the regeneration, healing, and repair of skin cells, and supports our healthy collagen production and skin elasticity. These benefits can also be applied to scars, fine lines, and acne, although the latter are usually treated with blue light.

Laurence Newman, founder and CEO of CurrentBody, said, “In clinical practice, there are benefits from skin regeneration (collagen production, fine lines and wrinkles, pigmentation) to healing (using near-infrared light).”. Reducing inflammation has more benefits than simply reducing redness: when applied to certain parts of the body, phototherapy (also known as phototherapy) may help reduce pain and even heal deeper tissues.

How often should you use red light therapy?

The frequency and duration of red light exposure depend on the “content” and “location” of the red light therapy device. “Red light devices in the office are much more powerful than those you use at home, and FDA-approved devices for home use are safer and more effective than devices that are not FDA-approved,” Bowe said. “When we think of at-home devices “I recommend that patients continue to use it regularly (daily or 3-4 times a week) for at least 6 weeks to give the device a chance to work.” Bao goes on to note that it can take up to three months to achieve skin tightening results. Routine red light care.

While benefits like improving signs of photoaging and boosting collagen production can take months, red light can calm inflammation within a 10-minute session (the amount of exposure dermatologists recommend).

“While in-office LED treatments are effective and popular, at-home devices are a more cost-effective and convenient way to use LEDs,” Newman said. “You can use it more consistently at home, resulting in better long-term results for your skin.” That said, red light is an additional complexion aid, not an excuse to skip skin care. “The best at-home results can be achieved by combining light therapy with a well-designed skin care routine,” says Murphy-Rose.


Are there any risks with red light therapy?

Red light therapy is generally considered a safe and effective method for all skin types, but there are some common-sense caveats. Step one: Close your eyes.

“If you keep your eyes open, the light can cause damage,” Bao said. Second, your red light device or your skin should never be hot, not even warm. “If the wavelength of light generates heat, it triggers the pigment-producing cells in the skin to emit more melanin, so if you’re prone to hyperpigmentation, you want to be especially careful not to let it radiate heat.”

Murphy-Ross added that if you have any conditions that make you more photosensitive or take medications that increase photosensitivity, it’s best to talk to your healthcare provider before using red light. Before purchasing expensive equipment, make sure it has been properly vetted. “I always recommend doing your research before investing in LED equipment,” Newman says. “Not all LEDs are made the same and it’s important to check that your device is operating at the correct wavelength to deliver the results you want and has been tested for safety.”

Still, the non-invasive treatment has essentially no side effects. Whether you choose to treat your skin condition at a spa or try light therapy at home, the positive results of red light therapy are worth your time and money.
