factional plasma Under the controllable way, the needle-shaped plasma column is released to the skin surface in a fractional way and dot by dot. The principle is to ionize the gas in the air to create more small electrical arches, tissues are treated to “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, leading to skin remodeling and improvement in various signs of aging and scarring, etc.
