Getting to know LED light therapy

LED treatment from the skin specialist/facialist is the use of low level light to exert a range of therapeutic outcomes from within the deeper layers of the skin. It is a minimally invasive treatment and has generated a lot of interest in the skin care industry in recent years, due to its ability to help improve a varied range of skin conditions.

The study of the interactions and subsequent effects of light on living organisms, their cells and their associated cellular processes is referred to as photobiology and it is an area of significant and mounting research particularly for the treatment of skin disease and disorders.

LED as an effective dermatology/medical treatment

Several cutaneous LED and UV light treatments, categorised in the Photodynamic Therapy treatment group are used by dermatology/medical professionals and have many positive and well documented medical treatment outcomes. These include the effective treatment of vascular lesions, skin cancer, skin cancer precursors and port wine birthmarks, however these types of treatment very much fall outside of the scope for a skin specialist or facialist using LED treatment, so they won’t be detailed further in this post to avoid confusion and the potential to mislead.

Which LED gives best results in clinic?

There are quite a few LED devices available to the skin specialist/facialist, but not all are equal in their therapeutic benefits. For an LED treatment device to be truly effective its light modules need to operate within a narrow range of researched wavelengths. LED was originally recognised as having a biological significance in the 1960’s and as the technology and the subsequent development of LED light modules has advanced, their application in clinic has become more relevant and effective. Modern LED light modules have the ability to emit therapeutic light with a very specific intensity, dose and narrow wavelength, that can be delivered effectively in either a pulsing or continuous mode. The result is a very targeted and therapeutically useful treatment tool for many skin conditions and all skin types.

The documented cellular effects of LED light therapy include the effective stimulation of ATP (Adenosine triphosphate). ATP is the key component of cellular respiration and unit of energy required to drive many cellular processes including modulating oxidative stress, stimulating collagen synthesis and upregulating angiogenesis (new capillary formation). Effective upregulation of such processes can provide a positive benefit to both the health and appearance of the skin.

Hitting the target

As previously mentioned, the accuracy in which an LED light source can target a cell is dependent on its intensity and wavelength. This dictates how effectively it can travel to the site of treatment and provides the correct biological stimulus to the target cell. The final therapeutic outcome is hugely dependent on a superior technical specification of the LED modules and the supporting technical development applied to the device by the manufacturer, to deliver these critical parameters for effective treatment. Without this combination, the LED device will not provide an effective treatment with a measurable therapeutic outcome.

Dermalux UK- Leaders in light technology

In my treatments, I use the Dermalux Flex MD LED device. It has a medical CE mark, which means it has solid clinical data to back the skin benefits and has received a recognised standard of research and development to support its therapeutic claims. Each Dermalux unit is hand built in the UK with their unique, custom manufactured LED Technology. It uses these specifically developed LED light components, positioned on a reflective surface to produce optimal light emission for proven skin benefits. It is this defined set of physical parameters that enable the established, positive treatment outcomes of the Dermalux Flex in comparison to some other devices on the market.

Here are the specification details and the skin conditions, which can benefit from treatment

Blue Light (415nm) has a low potential for penetration of the epidermis, which is useful for skin conditions that reside here such as mild to moderate acne conditions (triggered by bacterial colonisation of C. acnes (formally known as P. acnes) and some forms of actinic rosacea. The treatment actively supports the destruction of these bacteria improving skin clarity without irritation. It also has a calming effect for problem skin concerns

Red Light (633nm) is able to reach the dermal/epidermal junction with the ability to activate fibroblasts and increasing fibroblast growth factor expression as procollagen type 1 (A precursor protein to collagen production) and upregulating MMP9, an proenzyme which plays and important role in angiogenesis (increased capillary formation and strength) and enhanced wound repair. Treatment energises cells to accelerate renewal, boost collagen and elastin production and increase hydration for smoother firmer skin. Ideal for restoring vitality and glow.

Near Infrared (830nm)- This reaches maximum penetration of the skin and is effective in further supporting the wound healing cascade and stimulating angiogenesis (again by upregulating extracellular proenzymes such as MMP9. The results of these processes offer advanced rejuvenation benefits, promotes healthy skin, calms redness and irritation and helps reduce pigmentation.

Tri-Wave Therapy (415nm, 633nm & 830nm)- This is a unique combination of the three defined wavelengths designed by Dermalux, to help deliver a complete a rejuvenation outcome including underlying inflammation, photodamage and unwanted outbreaks on the skin.

Now you’ve seen the light

We know that skin ageing in particular is the result of intrinsic and environmental factors and is characterised by a reduction in both collagen and elastin synthesis, combined with increase cell damaging reactive oxygen species (free radicals) that degrade existing collagen and elastin

Research in photobiology has showed evidence in the ability of LED light therapy to trigger skin collagen synthesis and reduce damaging matrix metalloprotinase expression, which leads to the degradation of important structural proteins within in the extracellular matrix of fibroblasts (cells of the skin).

LED light therapy is an effective, safe non-invasive tool for the skin therapist/facialist to help provide treatment for inflammatory skin conditions and slowing age related cellular degradation. For the most effective in clinic LED therapy results you will need to receive a well-planned and prescribed series of treatments from a device that has been developed and tested to a specific, clinically recognised standard and it should be combined with a consistent, clinical skincare routine to provide longer term skin health benefits.

The treatment

LED light therapy has an accumulative cellular benefit on the skin, so for best results it should be taken as a course of up to three treatments per week for between four to six weeks, with a maintenance plan dependent on skin type and condition. However even a single treatment can improve post treatment inflammation and healing with a visible skin benefit. Each treatment session lasts around 30 minutes and can use a combination of light wavelengths, prescribed to your skin requirements. This treatment can also be added to other facial treatments that include peels or micro-needling, to aid the post treatment healing response and accelerate overall results. I also offer the Dermalux as standard in my Advance Plus Prescriptive Facial. LED treatment truly has a myriad of skin benefits aimed at improving overall skin health and appearance and one that most clients would observe a positive skin result
