Red Light Therapy Is Hot Right Now: Here’s Why It's Time to Get Into It

Celebrities like the Kardashians have been using red light therapy for years now, and it's one of the best-kept beauty secrets so far. Perhaps that's why Kim has that creamy, dreamy complexion many women would die for. 

And yet, it's not really a secret. Many A-list celebrities are on record parading their red light therapy home setups. We're talking Jessica Alba, Chrissy Teigen, Emma Stone, and many more. Celebrity aestheticians such as Shani Darden are front-line supporters of RLT, but why is it so hot right now if the technology is not new?

Why Red Light Therapy is Trending 

Red light therapy is so big right now because it is literally the magic solution for flawless skin. Unlike Korean skincare, facial masks, vegan and organic cosmetics, and lots of other fads, red light therapy is firmly rooted in science. The thing is, we are only just discovering how and why it works. 

Red light therapy is a treatment that involves irradiating the body using specific wavelengths of light in the visible range. This light, between 600nm and 1300nm, is absorbed into the skin and causes various cosmetic and health benefits. 

Perhaps the biggest reason why red light therapy is so big is the fact that it is one of the treatments that can actually reverse signs of aging on the skin. It can smoothen out fine wrinkles, eliminate acne, improve skin elasticity, and generally restore youthfulness to the skin. 

RLT does all this without requiring invasive procedures or expensive cosmetic products. It has no side effects whatsoever, which is why it remains a very attractive option for those looking for an effective skincare fix. 

Shani says that she loves red light therapy because of its repair and regeneration effects. It helps get rid of acne, heal psoriasis, and get rid of stretch marks. Her claims are backed by scientific studies that show the efficacy of red light therapy on the skin.

What Are the Benefits of Red Light Therapy, and How Does it Work?

Red light therapy relies on low-energy, long-wavelength light in the visible orange-red spectrum to irradiate and penetrate the skin. The cells in the skin's dermis and epidermis absorb this light energy, which then influences cell behavior on a nuclear level.

Red light therapy triggers increased energy production in the cell mitochondria. This in turn causes increased cell activity, causing all kinds of health benefits.

  • Increased Collagen Production

Red light therapy triggers the increased production of collagen by cells known as fibroblasts. These cells sit just below the skin, so absorbing red light helps them to produce more of this essential collagen. 

As you know, collagen helps to give the skin its elasticity and youthful look. It also makes the skin more supple and helps scars and wounds heal faster. 

Collagen is also a major building block of bone, hair, muscles, and tendons. Thus, irradiation with red light helps to heal and restore these parts, giving the whole body a plump and youthful look. 

  • More Fibroblast Cells

In addition to producing more collagen, red light therapy also stimulates fibroblasts to reproduce faster. Having more fibroblasts means that more collagen can be produced and older, worn-out cells are pushed outwards. The result is a smooth, radiant skin complexion and texture.

  • Reduced Inflammation

Red light therapy has been shown to help reduce inflammation and pain in the body, usually in conjunction with near-infrared light and low-level laser therapy. Scientists are still researching how this happens, but studies show that it can stimulate healing, relieve nerve pain, and increase the production of anti-inflammatory agents. 

This study goes further to pinpoint the positive effects of red light therapy in patients suffering from various injuries and inflammatory pain. In the skin, its biggest benefit is seen in faster healing, elimination of rashes and burns, reduced itching, and healing of redness.

It can go so far as to facilitate healing from skin conditions such as eczema, psoriasis, seborrheic dermatitis, and breakouts of rosacea, rashes, and pimples.

  • Faster Muscle Recovery 

After working out, muscle cells need time to recover and heal from chemical and physical exertion. Thanks to its anti-inflammatory and healing properties, red light therapy helps muscle cells recover faster and thus help to improve performance in athletes. 

  • Brightens the Skin

Increased cell regeneration in the skin is a prime benefit that restores youthfulness and radiance to the skin. Red light therapy leads to the increased formation of new cells, which then replace the old and worn-out cells above them. 

  • Fights Acne and Scars

Red light therapy can help fight pimples by killing bacteria in skin pores. It also reduces the overproduction of skin sebum, which can clog skin pores and cause pimples to form. In this way, RLT can help to fight acne and remove old scars from the skin. 

Who's Using Red Light Therapy?


Lots of celebrities are in on the latest beauty secrets. Red light therapy posts are now in every corner of Instagram and TikTok, but here are five of the biggest names to join this trend so far. 

  • Olivia Munn

Olivia says she has a professional red light therapy set up in her home, and she loves sharing them with her girlfriends when they come to visit. She told US Magazine in 2018, "One of the best things is the red and blue light mask … and I keep a zapper with me wherever I go."

  • Chrissy Teigen

Chrissy is a self-acknowledged ambassador of red light therapy masks. She has lots of Instagram posts about herself basking under the healing glow of red light therapy- see for yourself.

  • Kim Kardashian

Back in 2018, Kim was using a $2,000  home red light therapy system to help treat her chronic psoriasis. It seems to have worked because she later gave the treatment glowing reviews. Kourtney picked it up as well, so there's that.

  • Emma Stone

The gorgeous Emma Stone loves red light therapy. She has taken to giving portable RLT devices to all her friends and family every chance she gets. Can it get hotter than this?

  • Victoria Beckham

The posh Victoria Beckham keeps her skin flawless in many ways, but this year she's swearing by LED red light masks. As the founder of her own beauty line, you bet she knows what she's doing. According to Woman and Home, she said, "Red light is for collagen and blood flow."


Due to the combined benefits of red light therapy on the muscles, skin, and overall body health, athletes are getting drawn to red light therapy in increasingly large numbers. It is more effective for them, too, because muscle cells have a larger number of mitochondria and thus produce more energy. 

Red light therapy helps to prevent soreness in the muscles as well as pain, fatigue, and stiffness. Perhaps that's why elite athletes such as DeMarcus Lawrence, Keenan Allen, and Patrick Peterson are using RLT to help improve performance organically.
