The tip of the pen creates a plasma energy arc which is then transferred from the tip of the needle to the surface of the skin. The tissues of the skin are sublimated, or modified, during treatment. The treatment is extremely precise, meaning that the tissues surrounding the area of treatment remain untouched and intact. This results in the tightening of the skin in the desired area. As a result of this, excess skin is reduced and the remaining skin is toned, tightened, and the wrinkles are reduced.This method of skin resurfacing creates a controlled skin damage, which activates the normal skin-healing process. This process leads to skin remodeling, which then improves various signs of aging.Unlike other methods of skin ablation, there are no open wounds during the healing phase. Therefore, there is minimal risk of scarring, infection or loss of pigmentation.
