The Benefits of Light

The health benefits of light have been known for centuries: ancient Egypt, the Indus Valley, pre-imperial China, ancient Greece and the Roman Empire used it therapeutically and even marketed it. However, it was in the 20th century that phototherapy – one of the old names for photobiomodulation – took off. Its development was surrounded by a lot of mistrust, because light is a phenomenon composed of waves that are ‘not visible’ to the naked eye and that work in a particular way. Today, light therapy is gaining increasing recognition.

It is now recognized that light has an effect on cell metabolism: each of our cells contains a kind of internal energy factory, the mitochondria. If the mitochondria are not functioning properly (e.g. in case of inflammation), then the whole cell is affected. Light therapy will help the affected cells by providing them with the energy they (punctually) lack ATP (adenosine triphosphate)

Stimulating Cells to Help Them Function

This is the mission of photobiomodulation (PBM), formerly known as phototherapy, light therapy / light therapy: it will touch the cell, so that the latter enters ‘resonance’ and absorbs light energy; this energy will promote chemical and physical changes which will, in turn, stimulate the activity of the cell.

The result: the energy sent into the cell will participate in its healing and allow, among other things

  • cell regeneration, treatment and relief of pain (e.g. joint, tendons, rheumatic, chronic), soothing of inflammation, irritation, trauma, healing of lesions, treatment of skin disorders (e.g. psoriasis, red patches, rosacea, oedema).
  • Rehydration and rejuvenation (anti-ageing and anti-ageing action for skin rejuvenation), scalp care (e.g. hair regrowth), fitness and general well-being.

Depending on the context, photobiomodulation will be used :

  • as a complement to another medical treatment (including surgery), in order to potentiate the effects and help the immune system, or
  • in isolation, for example in aesthetic treatments.


There is never any apparent or violent reaction after a photobiomodulation session:

  • the technique is non-invasive and the light does not produce heat
  • the benefits of the light appear progressive, as the sessions go on. The number of sessions and their duration depend on the treatment to be performed.

Uses for everyone! 

Today, photobiomodulation (PBM) is used in several forms: by Low Voltage Laser Therapy (LLLT) or by LED therapy. All the devices offered by Mostleds concern LED photobiomodulation.

It is used for the treatment of human beings, but also for the treatment of animals.
