Hi Desree, thank you for the question.
Both of these machines use fractional laser technology to deliver the laser energy into the skin however, two different companies manufacture them. Pearl is produced by a company called Cutera (http://www.cutera.com/technology/ysgg-laser/pearl/index.php#1_1 ) and they use a YSGG laser. Fraxel (http://www.fraxel.com/) is the name of the company that produces various Fraxel laser machines and they predominantly use CO2 as their laser source.
I do not believe there is a great difference in results but it would be interesting to see split face studies comparing these two modalities. I believe you will get good results with either machine but these results are also dependent (to a great deal) on the operator using them (the settings chosen).
