How Does Red Light Therapy Work?

Red Light Therapy: Unlock the Power of Light for Healing and Wellness.

The Basics of Red Light Therapy

Red light wavelengths are administered to (shined upon) your skin and they penetrate to the cells below. Your mitochondria (the energy production centers or “powerhouses” of your cells) are stimulated, triggering the production of adenosine triphosphate (ATP). ATP is an organic compound within your body that is responsible for all biochemical energy transfer. It is frequently referred to as the “molecular currency” by which cellular energy is transferred throughout your body.


ATP is delivered to all of your bodily tissues and organs, elevating the energy level within your cells. Greater energy in your cells elicits higher oxygen levels, reduces inflammation, boosts your immune system, and improves your circulation.


Increased cellular energy activates the production of fibroblasts (specific connective tissue cells that create collagen and elastin). Collagen and elastin are the proteins responsible for maintaining your skin’s elasticity and suppleness, and they are also key players in your body’s natural healing process. Enhanced collagen and elastin levels result in your body having a heightened ability to heal itself, triggered at the cellular level.


Red light therapy is an emerging method of treating an almost infinite array of physical and mental health conditions and concerns. Its revolutionary healing properties and health benefits are increasingly recognized as successful in a wide range of applications including:

  • skin and eye health improvement
  • pain relief
  • weight management and cellulite reduction
  • treatment of depression and anxiety
  • injury and wound healing
  • treatment of certain diseases
  • increasing cognitive function
  • physical fitness enhancement, muscle-building, and recovery after exercise
  • improving overall bodily healing ability
  • thyroid health and boosting metabolism
  • many more assorted uses

Red light therapy is 100 percent natural and FDA-approved. It contains no harmful ultraviolet (UV) radiation and is safe for all ages and skin types.

Red light exists in a spectrum of wavelengths. The best wavelength to use depends upon the condition being treated and your specific objective(s). Certain wavelengths and ranges of wavelengths are known to have specialized healing abilities. 

Weight Loss, Fat-Burning, Cellulite Reduction, and Metabolism

Red light causes pores to form within fat cells, effectively killing them. In response to red light, lipids (fatty acid compounds) are expelled and dispersed from fat cells. Red light also stimulates adipocyte apoptosis, which is the natural death of fat cells.


Because your cells are more active, glucose (blood sugar) oxidation is increased. Glucose is burnt more efficiently via red light therapy, ridding your body of waste products more quickly.


Improved circulation also helps your cells dispose of unneeded waste more expediently.


Thyroid function is closely related to body weight. The thyroid is a gland that produces certain hormones in your body, many of which are linked to metabolism and weight gain or loss. Red light therapy assists with proper thyroid regulation.


Red light therapy promotes a healthy sleep pattern by releasing your body's natural melatonin, the hormone that helps regulate the body's sleep-wake cycle. Sleep is essential for maintaining bodily energy. If you don’t get enough sleep, or even if you sleep too much, it is nearly impossible for your body to reduce stress and sustain a healthy exercise and fitness regime. 


Red light therapy also serves to suppress your appetite, making it easier to manage food cravings and eat healthily.


Red light reduces inflammation in your body. Chronic inflammation is linked to obesity, so its reduction prevents the growth of further fat cells.


Please note - Red light therapy does indeed dissolve fat cells, but it works better in conjunction with proper diet and exercise than completely on its own. If you consume more calories than you burn (even while undergoing red light therapy), you will still gain weight (or stay the same, if caloric intake equals calories burned).

Skin Health and Reconditioning

Red light therapy has a powerful healing capacity, improves general facial skin health, acts as an anti-aging remedy, and treats numerous skin conditions and diseases. Red light therapy also helps to develop an even skin tone and a smoother skin texture, no matter what the problem.



Fine lines and wrinkles - Red light stimulates the production of fibroblasts and increases the production of collagen and elastin, thereby increasing hydration and cellular energy. The result is wrinkle prevention, reduction, and a smoother skin tone and texture. The skin becomes firmer and vibrant, with a more youthful appearance. Eye wrinkles, under-eye circles or hollows, bags, and “crow’s feet” can all be alleviated via red light therapy. Even deep wrinkles on the face and neck can be reduced with red light therapy, and shallow wrinkles and fine lines will virtually disappear.


Other conditions that create undesirable skin tone and texture issues and benefit from red light therapy include:

  • Sun Damage
  • Scars
  • Acne
  • Melasma
  • Eczema (Atopic dermatitis)
  • Psoriasis
  • Rosacea
  • Cold Sores (Fever Blisters, Herpes Simplex Virus Type 1 or 2)
  • Visible Veins and Broken Capillaries

Pain Management and Relief & Wound Healing

Red light therapy is well-known as a successful way to end chronic or temporary pain.


Inflammation is a predominant cause of pain, so red light therapy’s anti-inflammatory properties provide quick relief of any type of bodily pain. Better circulation, increased cellular oxygenation, better cellular nutrition, and improved ATP levels in your organs and tissues all result in pain relief.


Red light therapy addresses pain issues better than any drug or topical solution. Rather than temporarily dulling pain, red light therapy tackles the root cause at your body’s cellular level.


In wound healing, even stem cells within your bone marrow are stimulated and are deployed to the injury or wound site via red light therapy. This is significant because cells that are within close proximity to one another will communicate. Damaged cells at an injury site can potentially send harmful signals to neighboring cells, causing infection or prolonging healing time. Healthy stem cells, however, send the right message to damaged cells, signaling them to adapt to the properties of the newly arrived healthy cells.


The enhanced circulation quality stimulated by red light therapy increases the conveyance of oxygen, white blood cells, and nutrients to the wound or injury site, promoting healing even further.

Athletic Performance, Muscle-Building, and Post-Workout Recovery

Increased energy at the cellular level means that your body disposes of waste more expediently and your overall bodily energy is increased. This translates to improved stamina, endurance, strength, and speed, and a rise to your peak performance level.


Better circulation creates more capillaries (tiny blood vessels) to deliver oxygen and essential nutrients to your cells. Increased oxygenation and cellular nutrition result in less muscle damage during workouts. This means that you can boost your workout level, experience less exhaustion, sustain less tissue injury, and recover more quickly after exercise.


Muscle growth is compounded through ATP production and the resulting cellular energy boost. Your body’s new ability to work out more intensely naturally invokes a higher level of muscle development, and your muscle mass increases steadily.


Red light therapy is beneficial both pre– and post-workout.


Combined red and NIR light therapy can also prevent (or accelerate the healing of) sports injuries such as:

  • cartilage tears
  • knee injuries
  • tennis elbow
  • tendonitis
  • back pain
  • muscle strains or sprains
  • rotator cuff tears
  • Achilles tendon strains or tears
  • ”shin splints” (shin pain caused by overworking shin muscles and tendons), common in runners and dancers)
  • general joint, nerve, and muscle soreness

Mental Stamina and Cognitive Performance

Red light therapy provides great support for brain health. Brain cell function is improved, thus enhancing overall brain function. Red light therapy can increase mental stamina and cognitive abilities, treat psychiatric disorders and assist with the healing of a stroke (also known as a “brain attack” during which blood flow to an area of the brain is cut off).


Cerebral blood flow is increased, inflammation is reduced, stem cell production is revitalized, and metabolic cell function is improved via red light therapy. A process called neurogenesis is also stimulated. Neurogenesis refers to the regrowth of neurons within your brain. Neurons are fundamental brain and nervous system units that are responsible for receiving sensory input and sending appropriate signals to the rest of your body. Your brain gains a greater ability to form neural connections and function at a higher capacity.


Your ability to concentrate is improved, thinking and problem-solving skills are elevated, and overall mental sharpness and acuity are raised to new levels.


Depression, anxiety, and the symptoms of other mental illnesses can be lessened. Even degenerative brain diseases like Alzheimer’s Disease can benefit from red light therapy.

Beware of scams and devices sold for home use

By choosing professional-grade treatments, you can avoid these risks and ensure that red light therapy is administered safely and effectively by trained experts.

FDA Considerations

As red light therapy gains popularity, the market has seen an explosion of light-emitting products, many of which are not properly regulated. It’s important to understand that while red light therapy itself is FDA “APPROVED,” the devices used to administer the therapy are classified as FDA “CLEARED.” These non-invasive Class II medical devices undergo a less stringent approval process.

Unfortunately, some marketers falsely label their red light devices as FDA-approved, which is both inaccurate and illegal. Be cautious when purchasing devices online, as many of these products make unsubstantiated claims, may not work as advertised, and could even pose safety risks.

Choosing professional red light therapy at a trusted facility like Aura Light Therapy ensures you receive effective, safe, and expertly delivered treatments backed by advanced technology and proper protocols.
