Red Light Therapy

 what is it and how is it used?


Whilst red light therapy may seem like a recent buzzword, it is actually a technology that has been around for a long time.

In 1903 physician Niels Ryberg Finsen won the Nobel Prize for his treatment of smallpox and lupus using red light.

In Russia low level laser therapy is regularly use in standard medical care and has been since the 1970s.

In the 1990s NASA used red light LEDs (light emitting diodes) to grow plants in space – the LEDs sped up plant cell metabolism and photosynthesis.

But what exactly is red light therapy?



What is Red Light Therapy?


Red light therapy (RLT) also known low level light therapy (LLLT), photobiomodulation (PBM) and low-power laser therapy (LPLT), works by using low level wavelengths of light to penetrate cells.

It strengthens the mitochondria (the brain of the cell) and encourages enhanced cellular activity, in doing so, the cell will create more ATP (adenosine triphosphate). ATP is the energy-car

rying molecule, a cell making more energy will function more efficiently, and be able to rejuvenate and repair itself.


What are the benefits of Red Light Therapy?


Red light therapy has numerous benefits and can be used to treat a plethora of ailments. The production of ATP and strengthening of cells allows the body to heal and protect itself.


  • It helps rejuvenate facial skin and smooths skin tone.
  • Builds collagen in the skin to reduce wrinkles.
  • It helps to repair sun damage.
  • Red light activates the lymphatic system for potentially improved detoxification.
  • Decreases inflammation in the skin.
  • Helps fade scars and stretch marks.
  • Improves hair growth to reverse balding.
  • Stimulates slow healing wounds.
  • Can prevent recurring cold sores, or herpes simplex.
  • Helpful in the short term for carpal tunnel syndrome.
  • Beneficial for skin to reduce eczema, rosacea and acne.


RLT is heavily endorsed by many celebrities as well as aestheticians around the globe. The multiple benefits mean that it is a multi-tasking treatment that can help with skin issues from acne to wrinkles, stimulate hair regrowth and minimise stretch marks – potentially all at the same time!



Is it safe to use?


In short – yes. It is FDA approved and poses minimal health risks.


RLT can be safely used on all ages, to heal wounds in children, minimise acne in teenagers and promote hair regrowth in grandads!


Some light therapy devices may pulse or flash, which may not be suitable for those with a history of seizures. However, these devices can be avoided as many do not have this feature.


Studies indicate that red light therapy is safe during pregnancy, however it would always be advisable to confirm this with your doctor or midwife.


Whilst red light therapy poses no danger to eye health, some people find it too bright – wearing tanning glasses will make this more comfortable.


How do I get Red Light Therapy?

RLT is available in many forms. There are many spas and clinics that offer RLT treatments, often in the form of an opera mask – a mask that is placed over the face.

It is also possible to purchase RLT devices to use at home. It is advisable to ask an aesthetician or dermatologist for advice on how to use this to ensure you are using it correctly.

For hair loss, RLT can be administered via a helmet or alternatively through a brush or comb with Red light LEDs.
