Red Light Therapy Will Eventually Become The Source Of Youth.

Red light therapy is more and more popular all over the world.You can see them in the dermatologists’ offices and gyms.They promised to cure all your health woes with the flick of a switch.And it approved red light therapy is effective.

When i first time met the red light therapy product,i can not believe my eyes.The health care treatment can be so easy.Just need to press down the switch,The red light will cure the acnes,sore muscles from the celluar level.Sounds like a Panacea，you have to wonder: Too good to be true?

Through the experiments of experts,the red light therapy really effective in some health care application scenarios.Of course, there are some uncertain controversies.Here we will introduce how the Red Light Therapy works,and which benefits are ture and which benefits are not certain.

What is red light therapy?

RLT works its magic by delivering safe, concentrated wavelengths of natural light into your skin (around five millimeters, to be exact), where it’s absorbed by your cells. This “stimulates the production of collagen, elastin, and fibroblasts,” says Rhonda Klein, M.D., a board-certified dermatologist in Connecticut. That in turn enhances a little something known as ATP, the source of energy for every cell in the body (read: natural energy sans a 3 p.m. caffeine crash). “RLT also boosts circulation, bringing more oxygen and nutrients to your cells and tissues,” Klein says.

Translation? When your cells are hit with the red light wavelengths, a host of regenerative effects occur, leading to potential benefits like younger-looking skin, enhanced muscle repair, and diminished scarring.

As evidence for the benefits of RLT mounts, so do ways to soak them up. Professional wellness spots—your dermatologist’s office, local spa, or maybe even a fancy gym—offer a variety of options, from full-body panels that allow you to bask in the glow to smaller devices for more targeted treatments. You can also do DIY treatments at home with a handheld red light device, red light face mask, or even a RLT bed, if you want to go all in.

It’s not just any red light that delivers this performance-optimizing boost, however; two wavelengths of red light in particular—660 nanometers and 850 nanometers—deliver the best biological response, explains Michael Hamblin, M.D., an associate professor at Harvard Medical School. The former, 660 nanometers, is more quickly absorbed by the skin, making it the go-to for cosmetic treatments that address signs of aging, while 850 nanometer wavelengths penetrate deeper into your body to help with muscle recovery, joint pain, and full body health.

In other words, you can’t just pop a red light bulb into your desk lamp and expect to jump-start a cellular time machine. When you visit a professional, you can expect a treatment utilizing one of these optimal wavelengths, but if you buy a DIY device, be sure to check that it specifies an output intensity. “With so many devices coming out online, it’s a good idea to consult a dermatologist or other skin-care specialist to guide you on the most effective choice,” says Klein. (You should also be wary of tanning salons that swap out UV bulbs for red bulbs in tanning beds and bill them as “antiaging” treatments, she adds.)

Red light therapy benefits：

1.Speed Up Wound Healing

Wolverine-esque wound healing is just one of the many benefits touted by proponents of RLT.And clinical cases do prove that RLT can speed up wound healing. A 2014 study found red light therapy promoted “increased tissue repair and healing,and also has beneficial effects on wrinkles, acne scars, hypertrophic scars, and healing of burns.”

2.Muscle Relax,repair and recovery.

When it comes to muscle repair and recovery, evidence suggests RLT has benefits when used both pre- and postworkout. A 2014 study found that the therapeutic technique led to reduced muscle strength loss, less muscle soreness, and fewer range-of-motion impairments for up to four days after exercise. A more recent 2018 study also proved that RLT both before and after exercise reduces knee muscle fatigue.

3.Pain Relief

Pain relief is the most important needs for the RLT user.Research has proved that when the body expose under the red light ,it can relieve osteoarthritis knee pain, meniscus tears, general knee pain, rheumatoid arthritis, and back pain.FDA has approved Red light therapy as a effective device to relieve minor pains and arthritis.

4.Improving skin health.

This is the women’s favorite feature.Red light therapy can clear up acne,Pigmentation.“I wouldn’t traditionally recommend red light therapy for severe acne, but it’s a wonderful additive therapy that’s safe and well-tolerated by all skin types and tones,” says Angela Lamb, M.D., associate professor of the department of dermatology at the Icahn School of Medicine at Mount Sinai Hospital in New York City. The skin-clearing secret lies in RLT’s anti-inflammatory effects, says Klein.It also can reduce oil production and bacterial levels on your skin.

5.Antiaging.

There are many studies proving red light therapy has antiaging benefits.A 2014 study that determined that users of RLT experienced significantly improved skin complexion and an increase in collagen. “Science shows that red light therapy protects existing collagen and boosts new production,” says Lamb. “It also can improve with texture, tone, pore size, and wrinkles.”

6.Weigh Lose

Red Light Therapy opens, liquifies, and shrinks existing fat cells. This feature is a boon for obese people.

7.Enhancing bone Recovery

A review in the Journal of Photochemistry and PhotobiologyTrusted Source examines the potential for RLT in treating facial bone defects.The researchers’ results indicate that RLT may help accelerate healing after treatment for facial bone defects. The review also notes that the therapy helped reduce inflammation and pain during the process.However, the researchers did call for a more standardized approach to determine whether or not the therapy is effective.

8.Hair Regrowth.

A small study in the Journal of Cosmetic and Laser Therapy explored the effect of low-level light on people with alopecia.The study revealed that people who received RLT had improved hair density, compared with those in a control group.

The authors note that the effect was beneficial when people applied light in wavelengths of both 665 nanometres (nm) and 808 nm.However, this was a smaller study, and more extensive clinical studies will help give backing to these claims.

Red light therapy side effects

The Red Light therapy is controversial is that how many red rays we need to achieve these benefits.researchers haven’t yet nailed down the optimal dose.So when you decide to use red light therapy at home ,you’d better to consult a board-certified dermatologist first.

Even though the red light therapy is natural,almost no risk,but if you use a low-quality device or expose to the red ray too much time,may damage the skin tissue leading to burns and blisters.
