A Guide To Red Light Therapy: Answering 8 Commonly Asked Questions
July 25, 2019

Chances are, you’ve heard about red light therapy. It’s regularly featured in the news, and everyone from celebrities to professional athletes and Instagram influencers are hopping on the red light therapy bandwagon.

Although the benefits of red light therapy might seem like a modern-day miracle, it’s not a new concept to the medical community. In fact, red light therapy was first discovered more than 100 years ago.

However, as red light therapy has grown in popularity, so have questions surrounding its efficacy and treatment potential.

So, what is red light therapy? And what does red light therapy do?

In its most basic definition, red light therapy is the application of specific energy wavelengths to the body to upregulate cellular performance and achieve therapeutic benefits, including anti-aging, pain management, and wound healing.

Red light therapy has been studied and tested in hundreds of clinical trials over the past few decades, and it has proven to be safe and effective with no negative, harmful, or long-term side effects.

As the manufacturer of the only device cleared by the FDA to simultaneously emit blue, red, and near-infrared light energy, we’ve encountered many questions over the past decade.

Below are answers to the 8 most commonly asked questions about red light therapy:

How long has red light therapy been around?

Red light therapy first gained prominence in 1903, when Danish physicist Niels Ryberg Finsen was awarded the Nobel Prize for his invention of light therapy for skin tuberculosis.

However, red light therapy has come a long way in the 100+ years since.

NASA scientists first used red light therapy to stimulate plant growth on space stations in the 1990s, and then began wondering “what can light therapy do for astronauts?” shortly after.

Astronauts are required to work in very irregular conditions, and they often become susceptible to health risks such as muscle and bone atrophy and delayed wound healing during long-term space missions. This observation led scientists to discover that human cells require gravity to stimulate growth, and any fluctuation in gravity will disturb overall cellular function.

Using that logic, NASA tested red light therapy on astronauts, and found that it had the ability to improve cellular function and combat the effects of living in zero gravity environments. According to a NASA-led abstract from 2002, “LEDs stimulate the basic energy processes in the mitochondria (energy compartments) of each cell,” and an LED blanket device was found to be effective in the prevention of bone and muscle atrophy.

Based on NASA’s findings, the medical community at large began to recommend red light therapy for its therapeutic treatment potential.

So, what is red light therapy?

Red light therapy is the application of specific wavelengths of light energy to human tissue to obtain therapeutic benefits.

Red wavelengths penetrate deep into the skin’s dermal layer to specifically target cells at the source. The energy absorbed by the cells is then used to naturally improve cellular performance.

Low-level light therapy is delivered through light emitting diodes (LEDs), and it has the potential to treat a variety of skin and pain conditions.

You might have heard people refer to red light therapy in a number of ways:

  • Low Level Light Therapy
  • Light-Activated Biostimulation
  • Phototherapy
  • LED (Light Emitting Diode) Therapy
  • Photobiomodulation

No matter what you call it – the science behind red light therapy is the same.

How does red light therapy work?

Like plants absorb sunlight to power photosynthesis and boost tissue growth, human cells can absorb light wavelengths to stimulate the production of collagen and elastin. Red light therapy also boosts circulation to deliver oxygen and nutrients to living tissues.


Similar to photosynthesis, cells absorb red, blue, and near-infrared light wavelengths to power performance.Similar to photosynthesis, cells absorb red, blue, and near-infrared light wavelengths to power performance.

In other words, human cells can absorb particles of light (photons) and transform that energy into adenosine triphosphate (ATP), the main source of energy that cells need to power metabolic processes. The resulting elevation of ATP is then used to upregulate cellular performance and repair tissue damage.

When your body absorbs particular wavelengths of light energy, it converts that energy to produce more ATP, thus boosting the body’s natural ability to regain and maintain vitality.

What can red light therapy do?

Red light therapy is constantly being tested and trialed to evaluate its efficacy for a number of different treatments, and the FDA currently recognizes light therapy as a proven solution for acne, anti-aging, and pain management.

There is evidence to suggest red light therapy can also treat / relieve the following conditions:

  • Delayed wound healing
  • Hair growth in people with alopecia
  • Pain from carpal tunnel syndrome & arthritis
  • Faster healing of diabetic foot ulcers
  • Inflammation from psoriasis
  • Fine lines, wrinkles, and sun spots
  • Recurring cold sores from herpes virus
  • Scar tissue formation / appearance
  • Muscle & joint recovery after physical activity
  • Itching from eczema
  • Reduces chemotherapy side effects
  • Muscle stiffness and spasms
  • Reduce appearance of stretch marks

The list of red light therapy benefits is impressive, and it has the potential to grow as additional clinical trials are performed.

Is red light therapy safe?

Red light therapy is safe and clinically proven for the treatment of a variety of skin and pain management conditions. Red light therapy is also non-toxic, non-invasive, and an affordable alternative to prescription drugs and harsh topical treatments.

Unlike other types of light therapy treatments, LEDs do not contain ultraviolet (UV) rays, so there is no risk of cancer-causing damage to skin tissue.

In comparison to lasers, LEDs generate negligible amounts of heat and are not considered a significant risk to the general population.

What are the side effects of red light therapy?

In general, side effects from red light therapy are rare. If they do occur, they typically involve temporary redness of the treated area. Side effects are minor and do not last long.

Red light therapy treatment is non-invasive, painless, requires no recovery time, and can be used on all skin types and tones.

How much do red light therapy treatments cost?

Rates vary depending on where you live, but one 30-minute session at a dermatologist’s office can range from $25 - $85 or more.

However, red light therapy is more effective if you keep up with treatments on a regular basis. For anti-aging, for example, most professionals recommend 2-3 treatments per week, so visiting a dermatologist that often can be inconvenient and expensive.

Generic “at-home” red light therapy kits can cost $25 - $250+, but not all devices are created equal. Cheap options typically do not deliver the same results as professional-grade equipment.

If you’re looking to incorporate red light therapy into your weekly self-care routine, it’s recommended that you purchase a professional-grade device. All factors considered, spending a little extra on high-quality light therapy is well worth the investment.

Take Celluma SKIN, for example, which simultaneously treats both acne and aging. If you were to use Celluma SKIN 3 x per week for a year, the total cost breakdown would equal approximately $10 per treatment. After 2 years? Only $5 per treatment – much less than the $25 - $85 you’d spend in an office setting.

Celluma SKIN addresses both acne and aging in a single deviceCelluma SKIN addresses both acne and aging in a single device.

Where can I buy a red light therapy device?

There are a number of red light therapy devices on the market – you can even find products on Amazon. However – much like other “too-good-to-be-true” deals, you should be cautious before you buy.

If you want to invest in red light therapy, it’s worth the money to buy an FDA-cleared device; that way, you’ll actually see results from consistent treatment. Inexpensive, non-regulated devices are often ineffective, or stop working after a month or two.

Bottom line? Do your research and trust the professionals. Purchase a reputable device that has a proven track record of success – one that professional dermatologists and estheticians use with their patients every day.
