Wrinkles, skin lesions and scars can now be visibly improved without surgery, anaesthetics and hospitalization. The PLUSER FRACTIONAL laser joins the erbium laser's dermatological potential with the fractional scanner. With this accessory the laser's impulse is split into many spots in different selectable shapes, thus limiting the laser ablation to the surface of the skin. Resurfacing treatments will therefore heal much faster. The scanner can be used in the single pulse or the repeated pulse mode: the action of repeated pulses prevents the formation of craters on the skin's surface. The laser also stimulates the contraction of collagen and activates wound healing response immediately after treatment.
