LED Phototherapy Explained

What is LED Phototherapy?

Light Emitting Diode (LED) Phototherapy is a non-invasive treatment that targets specific non-thermal light to energise cells which triggers a cascade of bio stimulatory responses. It is scientifically proven for a wide range of indications including skin rejuvenation, acne and pigmentation to wound healing, psoriasis and pain relief.

Well evidenced for its regenerative and healing benefits, Phototherapy does not transfer heat or create trauma making it particularly effective to treat problematic and inflammatory conditions. With one of the highest safety profiles, it is pain free treatment without downtime and suitable for all skin types.

LED Phototherapy is now recognised as an essential skin care treatment due to its versatility and role in the foundation of skin optimisation and good skin health.

HOW DOES LED PHOTOTHERAPY WORK?

Phototherapy, meaning ‘Treatment with Light’ is based on the principle that all living cells have evolved to absorb and be influenced by light. Light is a powerful energy and when applied correctly, has a significant impact on how we look, feel and perform.

The mechanism of action is a natural response similar to that of photosynthesis through a process known as photobiomodulation.

The human body has an amazing capacity to heal itself and light plays a crucial role.

The treatment involves exposing the skin to specific wavelengths or nanometres (nm) from the visible (colour) and infrared (invisible) part of the light spectrum. Wavelength selection is crucial to the success of the LED treatment as it determines how effectively the light is absorbed. It is so much more than colour choice.

Achieving results with LED

Consistent and successful results with LED Phototherapy is determined by delivering precise clinically proven and scientifically evidenced parameters to ensure maximum light absorption by the target cells.

PROVEN WAVELENGTHS

There are over 3,000 independent clinical studies supporting LED Phototherapy but only three wavelengths (nm) have been shown over time to deliver significant therapeutic outcomes; Blue 415nm, Red 633nm and Near Infrared 830nm.

The use of Green 520nm, Yellow 590nm and 600nm are not supported by credible scientific research to deliver any significant therapeutic benefit.

If the wavelength does not match the target chromophore, absorption will be compromised, and treatment results will be limited.

Dermalux systems use only the three most clinically proven wavelengths delivered via our unique LED technology with a tolerance of +/-2nm. This ensures that all the light energy delivered into the skin is at the peak/intended wavelength.

OPTIMUM ENERGY

Whilst LEDs emit relatively low levels of energy, we know that not all light is absorbed by the required target due to the principles of reflection and scattering. Furthermore, delivering a lower energy dose over a longer time duration does not equate in results to a higher power treatment over a shorter exposure time.

To ensure optimum cell activation during the LED treatment, the delivered energy per second (joules), total absorbed energy by the treatment area (J/cm2) and the stability of photon energy emitted over the duration of the treatment are all key considerations.

Dermalux LED devices have been independently tested to verify the claimed energy outputs.
