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, specialised 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.
At this point, LED phototherapy should be differentiated from photodynamic therapy. Although both use LED light on the skin, photodynamic therapy requires pre-treatment of the skin with aminolevulenic acid (ALA) and this significantly changes the light reaction in the skin, and its uses. Photodynamic therapy and has significant recovery periods, unlike LED phototherapy which requires no downtime.
The blue light is primarily used for acne treatment.
Both lights can be used as a part of photodynamic therapy, which is a much more invasive treatment due to the pre-application of a substance called ALA on the skin. Photodynamic therapy is usually used for the treatment of various skin cancers and acne. Once again, photodynamic therapy is a vastly different treatment to LED phototherapy, and requires significant downtime/recovery period.
At The Victorian Cosmetic Institute, we utilise two LED wavelengths, namely 415 nanometers and 620 nanometers. Each wavelength has a particular property and depth of penetration.
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 porphyins 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.

There are a number of LED machines currently on the aesthetic market including machines such as the Omnilux. However, at The Victorian Cosmetic Institute we have collaborated with Rofin Industries, specialists in LED and light technologies, to create our own LED machine.
Our doctors specialise in light based treatments including LED phototherapy. We use this treatment in conjunction with other treatments available at our clinic to provide you with the best options for the treatment of various skin conditions.
Our LED lights are of the highest quality, and have been specially designed for our purposes.
