Does red light therapy slow aging?

Who doesn’t want to look and feel young forever? As we get older, we all want to hold on to our youthful vitality for as long as possible. This has led to a boom in anti-aging products and procedures promising to turn back the clock. Red light therapy has emerged as one of the most buzzed-about anti-aging treatments, said to impart a wide array of benefits from skin rejuvenation to pain relief. But does the science support the hype? As a savvy consumer, you want proof before investing time and money into any anti-aging strategy.

By the end of this article, you’ll understand the real potential of red light therapy for anti-aging – as well as smart strategies for tapping into its benefits yourself.

What is Red Light Therapy?

Red light therapy, also known as photobiomodulation or low-level laser therapy (LLLT), is a non-invasive treatment that utilizes red and near-infrared light to stimulate cellular regeneration and boost tissue repair. It exposes the skin to wavelengths of natural light between 600-900 nanometers, using LEDs (light emitting diodes).

When absorbed by the skin and cells, this red light energizes the mitochondria, which are the powerhouses of our cells. This boosts adenosine triphosphate (ATP) production, which fuels cellular activity and facilitates healing and regeneration.

Red light therapy is commonly used by dermatologists and aestheticians to reverse signs of aging, reduce inflammation, treat acne, promote wound healing, and alleviate pain. At-home red light therapy devices are also growing in popularity for their anti-aging and skin-enhancing benefits.

How Red Light Therapy Slows Down Aging?

To understand how red light therapy may slow aging, we need to start at the cellular level. Our bodies are composed of billions of cells that make up our tissues and organs. Within these cells are organelles called mitochondria that act as “powerhouses” to produce energy that fuels all bodily processes.

As we age, mitochondrial function declines. This leads to reduced energy production, impaired cell function, and the onset of degenerative changes over time. Research shows red and near-infrared light can boost declining mitochondrial function by inducing a biochemical effect in cells, stimulating energy production and revitalizing cell and tissue performance.

Specifically, when red or near-infrared light is absorbed by a cell, it activates mitochondria to produce more adenosine triphosphate (ATP), the main source of cellular energy. This causes a cascade of signaling effects that ultimately stimulate cellular repair and regeneration. Cellular communication is enhanced, inflammation reduced, antioxidants produced, damaged tissue repaired, circulation improved, and more.

In this way, red light therapy is thought to act as a catalyst that shifts cells into a reparative, youthful state. The light essentially “recharges” aging cells to help combat the gradual decline in how cells and tissues function. This potential to revive aging cells and tissues is why red light therapy is believed to have anti-aging effects throughout the body.

One of the biggest claimed benefits of red light therapy is a more youthful, radiant complexion. This is a key driver behind the rise of high-tech light panels in spas and dermatology clinics. But are the dramatic before-and-after images we see truly supported by science? It is true that multiple studies demonstrate red and near infrared light can improve signs of skin aging. Here’s a review of some of the evidence:

  • A 2006 study found that subjects experienced improvements in skin softness, smoothness, and firmness after nine sessions of red light therapy over five weeks.
  • A 2007 clinical study found that after eight 830 and 633nm red light treatments over four weeks, subjects experienced a significant 36% reduction in wrinkles and a 19% increase in skin elasticity.
  • A 2009 study found that red light therapy was effective in improving skin wrinkle depth and surface roughness, with more than 90 percent of people experiencing visibly smoother and firmer skin.
  • A 2014 study showed that red light therapy can regenerate skin and increase intradermal collagen.

While the body of evidence is still emerging, these results are promising. Red light appears capable of improving wrinkles, skin laxity, collagen production, tone/texture, and more – all key factors in more youthful looking skin.

Is Red Light Therapy Safe?

Red light therapy is considered very safe, with minimal side effects. The low-heat LEDs used in quality home devices pose no UV danger or risk of burns.

Red light is non-toxic and will not damage existing skin cells or tissue. It does not break down collagen like ablative laser resurfacing treatments. Most people find red light pleasant and relaxing.

Mild side effects like headache or dizziness can sometimes occur if sessions exceed 10 minutes. Redness or rashes may appear with photosensitizing medication. Overall, red light is gentle enough for all skin types with no downtime.

To ensure safe use:

  • Confirm your device emits light between 600-900 nm. Far infrared or UV could be unsafe.
  • Read all instructions carefully and don’t exceed recommended session times.
  • Avoid directing light into the eyes. Wear included safety goggles.
  • Ask your doctor before use if you are on medication or have health conditions.
  • Use strict eyewear and limit sessions if you have a photosensitivity disorder.

Is Red Light Therapy Worth It?

Given the research, red light therapy does appear to be a worthwhile anti-aging intervention. It is a non-invasive and low-risk approach to maintaining health and slowing age-related decline. But is investing in at-home red light therapy devices worth the cost? Here are some factors to consider:


  • Non-pharmaceutical option without side effects
  • Convenient at-home treatment
  • Addresses multiple aspects of aging
  • Easy to incorporate into routine
  • No recovery time required
  • Support body’s natural anti-aging processes


  • Purchase price of home devices ($200-$1000)
  • Ongoing energy costs for use
  • Daily 10-20 minute treatment times
  • Effects accumulative over time
  • Results can take weeks/months to notice


  • Effects likely gradual compared to cosmetic anti-aging options
  • Not a replacement for medical care
  • Benefits enhanced when combined with healthy lifestyle

Target Users

Those most likely to benefit from red light therapy include:

  • People looking for a natural anti-aging option
  • Individuals noticing first signs of aging
  • People with age-related chronic health conditions
  • Senior citizens looking to maintain health parameters
  • Middle-aged adults seeking prevention

While red light therapy requires an initial investment and ongoing commitment, it offers a drug-free way to combat aging without adverse effects. Given its broad health benefits, it can appeal to a wide demographic looking to slow age-related physical and mental decline. With a healthy lifestyle, red light therapy may be a worthwhile anti-aging strategy.
