What is LED Light Therapy?

LED light therapy has a fascinating origin story. It all began with NASA in the 1990s. NASA scientists were initially exploring the use of light-emitting diodes (LEDs) for plant growth experiments in space. But they stumbled upon something unexpected: these LEDs could also promote wound healing in astronauts. This discovery opened up a new world of possibilities for skincare and beyond.

How Does It Work?

At its core, LED light therapy uses light-emitting diodes to emit specific wavelengths of light. These wavelengths penetrate the skin at different depths, triggering various biological processes. For example, red light therapy typically uses wavelengths between 630 to 660 nanometers. This light penetrates deep into the skin, stimulating collagen production and reducing inflammation. On the other hand, blue light therapy uses wavelengths between 405 to 420 nanometers, targeting acne-causing bacteria.

The Science Behind the Glow

When these light wavelengths hit your skin, they interact with molecules called chromophores. These chromophores absorb the light and convert it into energy. This energy then triggers a series of reactions, such as increased collagen synthesis and improved blood flow. Collagen is a protein that keeps your skin firm and elastic, so boosting its production can help reduce fine lines and wrinkles.

Multiple Skin Benefits

LED light therapy isn't just for anti-aging. It can also treat a variety of skin conditions:

  • Acne: Blue light targets the bacteria that cause acne, helping to clear breakouts and prevent future ones.
  • Psoriasis: Some studies have shown that LED light therapy can reduce the symptoms of psoriasis by decreasing inflammation.
  • Wound Healing: The increased collagen production and improved blood flow can speed up the healing process and reduce scarring.

Real-World Applications

Today, LED light therapy is widely used in dermatology and esthetics. Dermatologists often combine it with other treatments like creams and facials to maximize results. You can also find a range of at-home devices, including LED masks, that make it easier to incorporate this therapy into your skincare routine.

In summary, LED light therapy is a non-invasive, science-backed treatment with a variety of skin benefits. From its NASA origins to its modern-day applications, this technology continues to revolutionize skincare.

How Do LED Light Therapy Masks Work?

LED light therapy masks use different wavelengths of light to target various skin issues. Here's a breakdown of how they work:

Light Wavelengths

Each LED mask uses specific light wavelengths to penetrate the skin and trigger beneficial changes. These wavelengths are measured in nanometers (nm) and each color targets a different skin concern.

  • Red Light (630 nm): Stimulates collagen production.
  • Blue Light (460 nm): Kills acne-causing bacteria.
  • Near-Infrared Light (850 nm): Promotes wound healing and reduces inflammation.

Molecular Changes

The light from these masks penetrates the skin and reaches the dermis, the middle layer of skin. This triggers molecular changes that can improve skin health.

Collagen Production

Red light is particularly effective in stimulating collagen production. Collagen is a protein that helps keep your skin firm and elastic. As you age, collagen breaks down, leading to wrinkles and sagging skin. Red light therapy helps to boost collagen levels, which can reduce the appearance of fine lines and wrinkles. According to a study with 52 female participants, red LED light treatment significantly improved eye-area wrinkles.

Bacteria Targeting

Blue light targets the surface layer of the skin, where acne-causing bacteria live. By killing these bacteria, blue light therapy helps to reduce and prevent breakouts. Research shows that blue light therapy can reduce acne blemishes by 46 to 76 percent after 4 to 12 weeks of treatment.

Skin Penetration

Different wavelengths penetrate the skin to different depths:

  • Red Light: Penetrates deeper into the dermis, where collagen and elastin are produced.
  • Blue Light: Stays closer to the surface, targeting bacteria in the epidermis.
  • Near-Infrared Light: Goes even deeper, reaching tissues below the dermis to promote healing and reduce inflammation.


LED light therapy masks use various wavelengths to penetrate the skin and trigger beneficial changes. Red light stimulates collagen production, blue light kills acne-causing bacteria, and near-infrared light promotes healing and reduces inflammation. By understanding how these wavelengths work, you can better appreciate the science behind the glow.

Next, we'll explore the specific benefits of each type of light therapy and how they can improve your skin.

Benefits of LED Light Therapy Masks

LED light therapy masks offer a range of benefits for your skin, from reducing wrinkles to treating acne. Let's break down how these masks can help you achieve a healthier, more radiant complexion.

Wrinkle Reduction

Red light therapy is a powerhouse when it comes to combating wrinkles. It works by stimulating collagen production in the skin. Collagen is the protein that keeps your skin firm and elastic. According to Abigail Waldman, clinical director of the Mohs and Dermatologic Surgery Center at Brigham and Women’s Hospital, red light LEDs penetrate the dermis and can boost collagen and elastin production. This helps to reduce fine lines and wrinkles, giving your skin a smoother, more youthful appearance.

Acne Treatment

Blue light therapy targets acne-causing bacteria. These bacteria live on the skin's surface and can lead to breakouts. Blue light penetrates the epidermis, killing these bacteria and helping to prevent future breakouts. According to Shoshana Marmon, a board-certified dermatologist, blue light also helps regulate oil production and reduce inflammation, leading to clearer skin. Clinical studies have shown that blue light therapy can reduce acne blemishes by 46 to 76 percent after 4 to 12 weeks of consistent use.

Inflammation Decrease

LED light therapy is also effective at reducing inflammation. Near-infrared (NIR) light, which penetrates deeper into the skin, can help reduce inflammation and promote healing. This can be especially beneficial for those with inflammatory skin conditions like eczema or psoriasis. Research funded by NASA found that NIR light significantly accelerated the healing process in various injuries, including musculoskeletal injuries and lacerations.

Skin Tone Improvement

Using LED light therapy masks can also improve your skin tone. Red and NIR lights increase blood circulation, which helps to deliver more oxygen and nutrients to your skin cells. This results in a more even skin tone and a healthy glow. Some masks even include green light, which can help reduce pigmentation and even out your complexion.

Texture Enhancement

Lastly, LED light therapy can enhance your skin's texture. By promoting collagen production and increasing cell turnover, these masks help to smooth out rough patches and improve overall skin texture. This can make your skin feel softer and more supple.

In summary, LED light therapy masks offer multiple benefits, from reducing wrinkles and treating acne to decreasing inflammation and improving skin tone and texture. These masks are a versatile tool in your skincare arsenal, helping you achieve a radiant, youthful complexion with consistent use.

Does LED Light Therapy Face Mask Work?

Red Light Therapy

Red light therapy is known for its ability to stimulate collagen production. Collagen is a protein that keeps your skin firm and elastic. When red light penetrates the skin, it reaches the dermis, the middle layer of the skin, and encourages fibroblast cells to produce more collagen. This helps reduce fine lines and wrinkles by making the skin plumper and more resilient.

A clinical study funded by NASA found that high-intensity red and near-infrared LEDs significantly accelerated the healing of oxygen-deprived wounds in rats. This same mechanism helps in reducing inflammation and promoting skin health.

Blue Light Therapy

Blue light therapy targets the epidermis, the outer layer of the skin, and is effective against acne-causing bacteria. Blue light penetrates hair follicles and pores, where it stops the metabolism of bacteria, effectively killing them. This helps prevent future breakouts and reduces existing acne.

According to Shoshana Marmon, a board-certified dermatologist, blue light also helps regulate oil production and reduce inflammation, leading to clearer skin. However, some experts are cautious about blue light exposure due to concerns about free radical damage, which can accelerate aging. More research is needed to fully understand these effects.

Other Light Colors

Green Light

Green light therapy has been shown to improve skin pigmentation issues. It works by inhibiting excess melanin production, which can help reduce hyperpigmentation and even out skin tone. Recent research from Rockefeller University presented at the Global Aesthetics Conference showed that green light increased growth factor and collagen pathways while greatly reducing inflammatory pathways.

Yellow Light

Yellow light is beneficial for reducing redness and inflammation. It penetrates the skin at a shallow level, making it effective for treating sensitive skin and conditions like rosacea. Yellow light can also improve photoaged skin, helping to reduce the appearance of sun damage.

In-office treatments use medical-grade devices that deliver specific wavelengths at precise power densities, making them generally more effective than at-home devices. However, consistent use of at-home LED masks can still yield significant results. For example, the Omnilux Contour LED mask recommends using it three to five times a week for four to six weeks to see noticeable improvements.

In summary, LED light therapy masks can be effective for various skin concerns, including wrinkles, acne, pigmentation, and redness. The key to success is consistency and patience. If you stick to a regular routine, you can achieve long-term benefits and healthier, more radiant skin.

At-Home LED Masks vs. In-Office Treatments

When considering LED light therapy for your skin, you might wonder whether to choose at-home LED masks or professional in-office treatments. Let's break down the differences.

Power Levels

In-office treatments use high-powered LED devices. These are more intense and can penetrate deeper into the skin. This is why they are often more effective in a shorter amount of time.

At-home LED masks, like the ones from Glow Therapy, are designed to be safe for daily use. They are less powerful but still effective if used consistently. According to Dr. Janiene Luke, at-home masks are not as highly powered as professional devices, but they can still be a good option when used as directed.


Both at-home and in-office LED treatments are generally safe. However, it’s crucial to ensure that your at-home mask is FDA-cleared. This means it has been tested for safety. Always follow the manufacturer’s instructions to avoid potential risks.

Eye safety is another important factor. Dr. Robert Layman emphasizes using blackout goggles to protect your eyes during light therapy. Some at-home masks come with built-in eye protection, but it's always good to check.


Professional treatments are often more effective due to their higher power levels and the expertise of the practitioner. They can target specific skin issues more precisely.

However, at-home masks can still deliver great results. For instance, the CurrentBody LED mask has been clinically proven to show visible improvements within four weeks when used consistently.

Dermatologist Supervision

In-office treatments come with the benefit of dermatologist supervision. A professional can tailor the treatment to your specific skin needs and monitor your progress. This personalized care often leads to better results.

Using an at-home mask means you won’t have this expert guidance. It’s a good idea to consult with a dermatologist before starting any new skincare treatment, even if it's at home.


One of the biggest advantages of at-home LED masks is convenience. You can use them anytime, anywhere, which makes it easier to stick to a consistent routine. This is particularly useful for those with busy schedules.

On the other hand, in-office treatments require appointments and travel time, which might not be feasible for everyone.

In summary, both at-home and in-office LED light therapy have their pros and cons. If you prefer the convenience and lower cost of at-home masks, be prepared to use them consistently for the best results. If you want faster, more targeted outcomes and don’t mind the extra effort, in-office treatments might be the way to go.
