Photodynamic therapy (PDT) is an innovative laser method of rejuvenation and skin treatment. This method came to the cosmetology from the general medicine, where it is recognized as one of the safest, but at the same time effective ways of treating various diseases. The advantages of FDT include the fact that when exposed it does not damage healthy cells, does not require anesthesia, does not have side effects and is very well tolerated by patients.
Over time, when using this methodology, in general medical practice, specialists discovered positive side effects that PDT showed in relation to the upper layers of the patient's epidermis. One of these effects was the skin rejuvenation. So PDT moved to cosmetology and began to be widely used in practice. This is not the first device for physiotherapy treatment, which was improved and began to be applied in aesthetic medicine.
After time, it turned out that photodynamic therapy allows you to update skin cells at the micro level. The essence of the method is that the device for FDT using a chemical reaction activating the energy of light allows selectively eliminating the problem areas of the skin in the field of face, neck, zone decolte, as well as hands. The FDT procedure implies the use of a semiconductor laser and a special gel with a photosensitizer, which is necessary to increase the sensitivity of tissues to the effects of light.
During PDT, a certain spectrum of radiation is created, consisting of light waves of different shades, whose task is to create light pulses. In this case, devices are used both with infrared and ultraviolet radiation. The color of the waves is selected with the patient's testimony. Thanks to light pulses, metabolism and blood circulation are enhanced, the balance of the upper layers of the skin is restored, moisturizing and skin softening occurs. Photorevation also has an anti-stress-effect on the skin and contributes to the removal of toxins. Thus, thanks to photodynamic therapy, the process of cell regeneration is launched.
In cosmetology practice is used Two types of photographic - Broadband and narrowband. The difference lies in the fact that broadband therapy implies the use of a wide beam of waves, narrow-band, respectively narrow. The disadvantage of broadband phototherapy is the impossibility of using it in hard-to-reach places, a narrowband treatment comes to replace this method.
