The Importance of LED
It is important to understand one fundamental element, that light LED therapy, in whatever forms it is applied, does not CURE any skin condition. The reason being when applied in correct does and the relevant wavelengths, light actually stimulates the body’s cells towards balance or to re-regulate themselves, resulting in cellular regeneration.
The body has an innate want to heal itself. The blood cells are on constant alert and go into action whenever called to when you are hurt, injured or under attack by pathogens or disease. Cellular tissue can self-repair at a specific rate. There are molecules within your cells called photo-acceptors that, when activated, accelerate or speed up your natural cell repair process
In the past thirty years, research has demonstrated that cell tissue responds to certain single frequencies of low power light. The light quanta (photons) are absorbed by the skin and underlying tissue, triggering biological changes within the body in a process known as “photobiostimulation”.
Absorbed by the epidermal cells and produce a cascade of events, the underlying tissue triggers biological changes within the body in a process known as a photo biological reaction. Monochromatic light increases oxygen and blood flow, accelerates wound healing, and facilitates pain reduction and muscular relaxation.
LEDs cannot be overused since cells will stop responding when healing is complete.
To create true photo modulation (which is where a cell will receive energy, then rested and given the energy again, allowing the cell time to convert and process this energy to create a chemical, biological and physiological responses) a skin cell needs to have information delivered and then a critical rest period for the same cell in this session so the cells can have time to process this energy for cellular regeneration.
Chemical – Mitochondria absorb oxygen and complete the break down of glucose to carbon dioxide and water to produce energy ATP that is used in life processes within the cell. Photosynthesis and cellular respiration is another example of a chemical reaction with in a cell created by LED.
Physiological – Absorption of light at the correct wavelengths to create a response that alters secretions within the hypothalamuses thus aiding in a more regulated hormonal activity. The physiological response of LED is beneficial to those with sleeping disorders, jetlag and mood disorder.
Biological – The body can create a wound response its self aided by the correct wavelength enhancing healing and regeneration.
• Increased circulation
• Strengthening of capillary system
• Increase lymphatic system activity
• Increase in RNA and DNA synthesis
• Stimulates fibroblast activity
• Increase Phagocytises (beneficial for fighting infection)
• Induces a thermal effect within the heart of the cell
• Stimulates tissue granulation (healing process of wounds)
How does it work?
LED Photomodulation uses low intensity light emitting diodes to create a process similar to plant photosynthesis whereby plants use chlorophyll to convert sunlight into cellular building blocks.
The light emitted by the LEDs is absorbed by epidermal cells and produces a remarkable cascade of events.
ATP, (Adenosine Triphosphate) the form of energy that cells utilise, is produced in this process and used to power the metabolic processes that synthesize DNA, RNA, needed proteins, enzymes, and other biological materials needed to repair or regenerate cell and tissue components; foster mitosis or cell proliferation; and/or restore homeostasis.
Studies of LED Photomodulation have shown skin textural improvement accompanied by increased collagen deposition with reduced MMP-1 (collagenase) activity in the papillary dermis. Using Photomodulation, scientists theorise that we are both slowing down collagen breakdown and building up new collagen.
The light emitted by the LED’s is absorbed by epidermal cells and produces a remarkable cascade of events. Increased Fibroblast activity and collagen synthesis are some of the results.One of the benefits of LED Photomodulation is that a wide range of Fitzpatrick skin types can be treated safely. Because of the low-intensity and specific bandwidth control of the light source.
With this in mind, LED Photomodulation offers novel, safe, non-ablative approach to photoaging when used in conjunction with specific skin care products.
