Fractional Plasma Working Principles : Under the controllable way, the needle-shaped plasma column is released to the skin surface by the fractional way and dot by dot.The principle is to ionize gas in the air to create more small electrical arches, tissues are treated “sublimate” and avoid spreading unwanted heat to the surrounding areas. The heat widens and is subsequently transferred into the epidermis all the way to the papillary layer which contains fibroblast cells. The result is contraction and tightening of the skin cells, leads to the skin remodeling and improvement in various signs of aging and scar etc.
