What is Light Therapy?

Light therapy, also known as photobiomodulation, is the process of creating energy from light—a vital factor for survival of all living things.

Light Therapy

Did you know there are ways to manipulate light waves into correcting the issues forged by ultraviolet (UV) light? At NuFACE, we’re always on the cutting edge of technology. For example, our microcurrent technology has revolutionized skincare, going deep down to the muscle to tone, lift, and sculpt the face. We also produce advanced light therapy skincare. Our light-therapy attachment has been lab-tested and FDA-Cleared to increase collagen production, correct discoloration, and reduce inflammation safely and effectively. Continue reading to learn about light therapy, the different ways you can use light to treat skin, and how to maximize results for your skin!

How Does Light Therapy Work?

Plants use chlorophyll to convert sunlight into food and energy through photosynthesis to help the plant flourish. The same goes for our skin. Different wavelength colors of light trigger natural, intracellular reactions within our skin. Each color of light naturally obtains a different wavelength that penetrates the skin at varying depths, resulting in unique energy that has biologic effects in the skin.

  • Infrared - Not visible to the naked eye. Stimulates fibroblasts to increase collagen and elastin; promotes circulation; minimizes appearance of pores.
  • Red - Stimulates the body’s natural healing response. Increases collagen and elastin production; boosts cell energy; reduces inflammation and damage caused by oxidative stress.
  • Amber - Soothes and calms the skin; improves the look of dull skin.
  • Green - Addresses skin pigmentation; calms inflammation; helps broken capillaries.
  • Blue - Kills some bacteria associated with acne; reduces oil production; calms and soothes skin¹.

What is Red Light Therapy?

Red light therapy is a treatment that helps skin, muscle tissue, and other parts of your body heal. It exposes you to low levels of red or near-infrared light that is a proven method of reducing fine lines and wrinkles, backed by numerous research and clinical studies. In aesthetic applications, red light is often emitted through LEDs (light emitting diodes) which produce light energy with very little heat, providing a non-invasive, comfortable experience for the client. It is a safe and effective technology for clients who wish to naturally reduce fine lines and deep wrinkles, while improving the overall appearance of the skin. Optimal red light therapy results are achieved with regular use, with the most noticeable reduction of fine lines and wrinkles occurring at 6 to 8 weeks of treatment.

Red Light Therapy has been Clinically Shown to:

Reduce fine lines and wrinkles

Encourage an increase in elastin and collagen production

Reduce the appearance of scars

Improves facial texture and feel¹

Improve skin complexion¹

Temporarily increase local circulation

Increase ATP production

Promote wound healing

Stimulate hair Growth

Red light therapy devices have increased in popularity in recent years as an easy-to-use and non-invasive anti-aging treatment that can be done at home.

Origin of Red Light Therapy

To find a solution for growing plants and feeding astronauts in space, NASA enlisted the expertise of plant biologists, who looked to LED lights for the answer. Once LEDs proved to be successful in plant growth, NASA investigated the use of LED therapy in tissue healing and found positive results². This research fueled the development of innovative and powerful LEDs that are now used in a variety of medical and aesthetic applications.

Some red light therapy devices utilize a flashing of the red light during treatment to provide a stronger more efficacious treatment for treating lines and wrinkles. This is because as the device flashes, it decreases the heating response in the skin and allows the wavelength to penetrate deeper into tissue with a higher average power than using a continuous waveform³.

Continuous wavelength therapy is more commonly used for pain management as it allows cells to relax, reducing pain and inflammation. For greater cosmetic benefits pulsed light is used to oppose this relaxation and increase ATP by up to 4X more than continuous wavelength treatments—partially due to the high energy dense skin can tolerate with the flashing mechanism⁴. Studies also found that when cells were treated with a pulsed laser light they began to produce more protein than on their own.⁵

Red light therapy devices have increased in popularity in recent years as an easy-to-use and non-invasive anti-aging treatment that can be done at home6. Devices range from smaller, concentrated treatment attachments to wearable masks and full-body panels.

Red light therapy devices are regulated by the FDA in the US and international governing bodies globally, which enforce the highest standards for safety and require rigorous testing to gain clearance to be sold. However, not all devices sold into the market are cleared by the FDA and meet these international safety standards.

Clinical studies are commitments made by companies to show the true efficacy of their devices used—all studies are monitored and performed by professionals, such as dermatologists, to maintain the validity of the product.

Light therapy penetrates deep into the skin, down to the dermis (where collagen is made to retain our skin’s flexibility). Here, the “light emitting diode” (LED) comes in the form of both masks or portable lights for different intensity levels.

Skincare light therapy can target the wrinkles we mentioned before. Still, LED light therapy can also be very beneficial for those who suffer from certain skin conditions or those looking to support their overall skin wellness. You can also use red light therapy at home to help reduce the appearance of discoloration and dark spots from the sun’s UV rays.

There is a wide variety of light therapy on the market, and you’ll need to pick the right lighting color based on your needs. So whether you’re looking for a youthful glow or clearer skin, LED therapy has you covered!

One of the most popular forms of light therapy is red light therapy. This type of LED wavelength only focuses on the skin epidermis. This is the skin’s outside layer, and when this area is targeted, it results in more collagen, increased energy of cells, support for blood circulation, and skin-soothing benefits. In addition, since this is low-level light therapy, it is highly safe and an entirely non-invasive procedure to support skin health.

Another popular form of LED light therapy is blue light therapy. This light activates a drying effect in the skin deep in the oil glands, which can help ease specific skin issues. For example, acne and clogged pores are often a result of the overproduction of oil and tampering down on these glands is one of your best lines of defense. It is also known to combat bacteria on your skin, which in turn can reduce blemishes.

If you’re looking for the most intensive form of LED therapy, look into infrared light for the ultimate skin rejuvenation. It benefits blood circulation and helps draw blood through the skin for more natural pigment in the face. So ditch the blush and say hello to infrared wavelengths of light!

One of the best ways to perfect the LED light therapy procedures is to ensure you put in the time and effort even after a session has ended.

The light therapy sessions should last anywhere from a half hour to an hour, depending on the machine used and how much area it covers or how powerful it is. This procedure may need to be repeated on a weeks-long basis. Smaller LED light therapy tools can be used for about ten minutes daily, and results are immediately seen.

Before and after your session, take some time to create an easy-to-follow skincare routine. Moisturizers, serums, and light exfoliants are all essential to long-lasting results. Unfortunately, there are no quick fixes for boosting collagen and sculpting your face — the more effort you put in, the better impact additional tools will create!

For example, we recommend using Prep-N-Glow Facial Wipes, our Super Antioxidant Booster for tightening skin, hydrating Aqua Gel Activator, and a Clean Sweep Brush to layer it all on.

The best part? All our products are clean, cruelty-free, and clinically tested. They are also all created by licensed aestheticians, making for only the best formulas and performance. In addition, we cut no corners in delivering top-notch sustainable skincare.

With the world of skincare constantly in evolution, you may feel slightly intimidated. We hope you’ll use NuFACE as an educational resource to make the safest, most informed decisions about your skin’s health. Light therapy passes the test!
