LED Therapy (LLLT) is a treatment we provide at our Reading skin clinic to help with a number of skin conditions. The power of light has been found to impact human tissue in a beneficial way. LEDs are light emitting diodes, which are gentle light waves but have a good therapeutic action and are not harmful to the skin. LED is the only aesthetic device that has no contra-actions of any kind. It is good for all skin types, skin colours and conditions, It is also safe for the eyes and it cannot be overused.
Light is made of photons, which are tiny particles of electromagnetic energy. The way light travels is as waves, which are measured in nanometers (one billionth of a metre). In LED light therapies we focus on the portion of the light spectrum that is visible (400nm violet to 700nm red) and contains all the colours of the rainbow. The effects on the skin depend on the length of the waves.
Individual visible wavelengths have a specific target chromophore within the skin (such as melanin, haemoglobin, water, cytochrome c oxidase, porphyrins etc.). Shorter wavelengths that have more superficial targets and longer wavelengths penetrate to targets at deeper levels in the skin. If the wavelength does not match the target chromophore then there will be no absorption and no reaction and therefore will have no beneficial result.
When the therapeutic light energy is in the correct wavelength, the cells in the dermis layer of skin triggers ATP (adenosine triphosphate) synthesis by the Mitochondria energy powerhouse of cells which in turn provides the essential energy that is needed for cell renewal, nutrition and removal of waste material. Healthy cells create a good environment to generate collagen (which gives the skin fullness or plumped look) and improve elastin (which gives the skin the ability to bounce back).
Blue light – Destroys p-acne bacteria to produce oxygen, which creates an unfriendly oxygenated environment for the p.acnes bacteria. This helps regulate oil production, and reduces sepsis and inflammation in active acne vulgaris.
Green light – Is used to even out skin tone and targets melanocytes, slowing down the production of melanin so not as much pigmentation reaches the top layers of our skin. It also calms erythema.
Yellow light – Stimulates toxin elimination, reduces congestion and stimulates lymphatic production.
Amber/orange light – Is particularly good for soothing the effects of rosacea and erythema.
Red light – Restores cell function activity. This is therefore the best light for anti-aging procedures.
Near Infra-Red light – Penetrates to deeper tissues improving pain and inflammation as well as helping to speed up the healing process after treatments.
Combining colours has been shown to be even more effective for optimising skin health across the board than one light treatment on its own. For example a fusion of red and blue light can produce the most successful outcomes in treating acne and inflammation in particular. We can therefore treat a number of different skin concerns at one time for our clients.
