Title: METHOD AND SYSTEM FOR SKIN TREATMENT
Abstract:
A method of skin tissue (1) treatment is provided which comprises the steps of: determining a treatment zone (9) within the skin tissue below the skin surface (3); modifying an electrical conductance property of at least two first skin tissue portions (11) present on opposite sides of the treatment zone with respect to a direction parallel to the skin surface; and providing radio frequency (RF) energy to the treatment zone via said first skin tissue portions. The step of modifying said first skin tissue portions comprises decreasing electrical impedance for the radiofrequency energy, in particular increasing electrical conductance, of said first skin tissue portions relative to a second skin tissue portion present between said first skin tissue portions; and such that said first skin tissue portions extend into the skin tissue substantially from the skin surface to treatment zone. A system for skin tissue (1) treatment is also provided.
