For microdermabrasion-induced injury, coarseness of the grit is only one part of the picture, Salomon said. "The duration of application, pressure applied during the application and the recipient skin thickness are also parameters, just like different grit of sandpaper are used for different types of wood and different types of applications," he said.
Treating the skin first with chemical peeling agents can reduce the amount of grit needed to get a skin-repair response equivalent to that of a coarser-grit wand, Salomon said. "So there are a variety of parameters that can be manipulated to achieve equivalent results, independent of the coarseness of the grit," he said. "In the end, you do need to induce an injury to the skin to get objective evidence of skin rejuvenation."
