LED Light Therapy
Led light therapy (Photo modulation)
LED stands for light emitting diode. These are very small semiconductors that emit light when a current is passed through it. In the past few years, specialized therapeutic LEDs that have extra luminescence emitted through a very specific wavelength band, have been used for the purpose of skin rejuvenation. Unlike laser or IPL, LED phototherapy is non-invasive and non-thermal, and hence requires no recovery time after treatments. Also LED phototherapy involves the use of continuous light rather than pulses of light.
Different wavelengths of LED can be used for to target various skin conditions from acne to ageing skin. Each wavelength will penetrate a different depth and cause a different effect within the skin.
This technology was originally developed by NASA to improve wound healing and tissue growth in space. It assisted with tired and fatigued astronauts upon their return. The potential of this technology was uncovered and introduced into the medical markets.
How does LED phototherapy work?
LED phototherapy works by using the properties of a certain wavelength of light to induce changes in the skin to treat a particular condition. There is no heat energy or tissue damage induced by LED phototherapy.
Blue light, treats one of the causes of acne, the bacteria propionibacterium acnes. It targets the metabolic product of this bacteria, porphyrins, and produces an oxygen free radical from these porphyrins that destroys the bacteria.
Red light (620nm) LED phototherapy induces a mild inflammation of the target cells and sets up an immune response that helps to regenerate these cells. This helps to rejuvenate skin and to help with skin healing. It can be used for skin rejuvenation, or post laser/chemical peel treatments to speed the healing process. Red and blue light LED phototherapy can be used synergistically to treat active acne, the blue light helping to reduce bacteria counts and the red lights helping to heal the skin.
Again, both blue and red light treatment have no side effects on the skin and require no recovery period.
How many treatments are required?
For the treatment of acne, clinical trials have shown that a treatment twice a week for 8 weeks, followed by once a week for 4 weeks helps to reduce bacteria counts and inflammation associated with acne, and therefore reduce the number of active acne lesions. The red light and blue light LEDs are alternated each session.
When red LED light is used for facial rejuvenation, treatments can be done from 1 to 4 weeks apart, and the more treatments that are performed, the better the result. This can be incorporated into one’s skin maintenance regime.
What machine do we use?
There are a number of LED machines currently on the aesthetic market. There can be significant differences between the light emitted and the quality of the light. After some trials of various machines, we have found the BIO-light to be the most effective machine available in today’s market.
