Figure 2 Patient two (A) before and (B) after treatment


This device comes in the form of a bed, with two side


arms on which there are two LED panels. The patient lies on the thermoplastic plate that is located above the LED, and the panels are placed on any other optional area of the body in order to treat the entire body at once without moving the patient or the device. This is a significant advantage in the homogeneity of the treatment compared with all the other devices on the market which, given their small size, can only radiate one area of the body at a time. Thus, the intermediate areas receive a double dose of light (i.e. double the amount of joules). If the initially planned dose of light on the cells is exceeded, the effect generated by the first radiation dose is rapidly and completely cancelled25, 26


. The second advantage of the Chromospace treatment


is the grid of LED. This unique concept allows a perfectly homogeneous irradiation of all the treated areas since all beams of the LED of the same colour perfectly intersect on the patientÕs skin. There is, therefore, no ÔholeÕ or


Ôenergy lossÕ between two LEDs owing to their distance; all the cells in the irradiated area receive a dose that equals 100% of the energy. In addition, power density, which indicates the degree


of concentration of power output by the number of LED, is also increasingly proven to play a significant role. If we take the example of a circular area with a diameter of 5 mm (0.2 cm2


) illuminated by a beam operating at a


power of 100 mW, the biological effects are very different from those produced by illuminating a circular area of 5 cm in diameter (c. 20 cm2


) with the same beam. In the


first case, the power density is 100 times greater than the second. Some studies have concluded that the power density may be of greater importance even than the dose. Thus, power density can vary within the irradiated areas according to the power of the LED, the irradiation time, the opening angles of the beams of the LED, as well as their distance, and the distance of the treated area from the peak of the LED light beam. However, it is necessary to remember that the basic law of photochemistry, known as the Grotthus-Draper law, specifies that only the radiation absorbed by the system, such as a molecule, can initiate a photochemical reaction. Finally, taking into consideration the surface of radiation, the Chromospace M.U.S.T. Leds allows for the

treatment of maximum areas of the body in minimal time (less than 40 minutes for all areas; front, rear, sides, inner surface of the legs). With other devices on the market, even with an accuracy of a radiation dose treatment at the same distance (3 cm exactly) and the best performance of LED beams, it can sometimes require more than 3 hours every week to work effectively. The fact of not having to move the panel of LED light to


treat each area, one after another, allows for irradiation with a single dose only in the intermediate zone, as stated by Karu; Ôa reversal of the effect obtained previously with ÔdumpÕ energy cells involvedÕ 25, 26

Radiofrequency The selected device for this study was the ThermaLipo Thermamedic , a multi-frequency bipolar device, based on a thermoselective system of RF induction, which can provide energy to quickly raise the temperature, primarily of the hypodermis and afterwards the temperature of the dermis, without causing pain, and to change the frequency according to the impedance of the crossed layers.


Method Each session begins with RF. The temperature is quickly raised to 39–40 C on every stretch mark area in a single pass. Next, a 70% glycolic acid peel is applied for 15 minutes and then rinsed; this is done every second session up to the eighth session. Finally, the patient is laid down on the Chromospace M.U.S.T. Leds table. The operating mode is set to 17 minutes for white skin, 8 J/cm2


,


with the red light at 645 nm pulsed at 50 Hz and infrared light in continuous mode at 855 nm. During the first month of treatment, the rate of


treatment is two sessions per week, and in the following 2 months the rate is one session per week ® this results in a total of 16 sessions. The treatment outcomes will generally continue to make progress, though it may appear that more sessions will be necessary. Throughout the period of treatment, patients were


asked to maintain their weight in order to avoid any impact on the stretch marks. Three months after the completion of treatment, patients were invited to attend a final evaluation. Only 30% attended, the majority of
