Study the Effect of Pulsed Dye Laser Versus Carboxytherapy in the Treatment of Striae Rubra

PDL (Cynosure - Chelmsford, MA-USA) wavelength 585 nm at a fluence 2.5-5 J/cm2, pulse duration of 0.5 ms and spot size 7 -10 mm

"carboxytherapy (Carbo - Programmable automatic carbon dioxide therapy apparatus, MA-USA) that was automatically calibrated to adjust the flow rate, through regulation of infusion pressure and the dosage of CO2 in ml. the infusion velocity consequently was adjusted to a flow rate of 1 cc/. The injection performed slowly, subcutaneously, by tilting the needle at 15 degree using a sterile disposable insulin needle, with the depth adjusted at 2 mm. the gas volume per injection spot is 2ml with 1.5 cm spacing between each injection point. End point was skin distension with the gas giving the characteristic popcorn appearance."
