Answering FAQs About Red Light Laser Therapy

What do you know about red light laser therapy? RLT is getting more attention in the media and on social platforms with influencers and sports stars talking about how RLT changed their life. So, what is RLT? It's the application of red light to the skin's surface, offering you several health benefits.

You receive the therapy from a red light device specifically designed to emit wavelengths between 620 to 700-nm. These wavelengths penetrate around 10mm deep into the surface of the skin. There are a few different names for RLT, and you might have heard people refer to it as any of the following.

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

Regardless of the name of the therapy, they all use LED red light technology to produce the same effect. We realize you might have a few questions about red light therapy, and if it's the right choice. Check out this list of FAQs for more insight into the benefits of RLT.


What Is Red Light Therapy and How Does It Work?

The skin absorbs low-level red light therapy to energize the body at a cellular level. Red light boosts ATP production – making us feel alive and vital. These wavelengths also stimulate the production of the proteins collagen and elastin, helping restore a youthful look to your skin.

Red light therapy (RLT) helps to enhance your circulation, providing more oxygen to the muscular system and brain. As a result, you think clearer and feel energetic throughout the day.

As mentioned, red light therapy helps to boost the production of adenosine triphosphate (ATP). ATP is the source of cellular energy that powers metabolism, and enhanced ATP means a higher metabolic rate.

Therefore, with a higher resting metabolic rate, you'll start to burn off excess body fat stores, losing weight without ever setting foot in a gym.


What Can Red Light Laser Therapy Do?

There are so many advantages for RLT. The FDA already recognizes RLT for pain management, anti-aging therapy, and acne treatment. However, the benefits of this technology go much further. There s plenty of anecdotal evidence that suggests red light therapy could offer the following health benefits.

  • Enhanced wound healing times
  • The stimulation of hair growth for people with alopecia
  • Pain relief from carpal tunnel syndrome and arthritis
  • Reducing inflammation in people suffering from eczema and psoriasis
  • Anti-aging for treating sunspots, lines, and wrinkles
  • Relief from recurring cold sores
  • Healing of scar tissue
  • Enhanced muscle recovery after exercise
  • Improved recovery to joint injuries
  • Helps improve mobility from muscle spasms and stiffness
  • Reduce the appearance of unsightly stretch marks from weight loss or childbirth

While the need for clinical data exists to verify RLT as a valid treatment for these issues, the anecdotal evidence is substantial and worth noting.


Is Red Light Laser Therapy Safe?

Red light therapy is proven clinically safe for use on human beings. There is no toxicity from being exposed to red light for extended periods. However, the benefit of more prolonged exposure will eventually taper off.

If you're using a red light device at home, stick to the protocol recommended by your therapist. Extending your therapy sessions won't provide any additional benefit.  

RLT contains no ultraviolet (UV) rays, and there is no risk that you can develop skin cancer from overexposure to a red light device.


How Many Red Light Laser Treatments Do I Need?

The amount of treatments you require depends on your needs. For anti-aging, we recommend two to three treatments for 20 to 30-minutes each session.

For injury recovery and healing, we recommend adding an extra session each week. Try to keep your RLT sessions at least 48-hours apart for the best results.
