During the session, the EXILIS computer-controlled device is guided over the treatment area. Patients feel a warming sensation as the energy is delivered to the deeper layers of skin. The ability to focus the energy on specific areas at the targeted depth of penetration makes EXILIS a highly effective aesthetic solution. The device engages the cooling system to heat deep tissue as it is constantly monitoring the skin’s temperature facilitating a comfortable, even treatment. To favorably influence the upper skin layers, only controlled heating is engaged to redefine loose skin and smooth wrinkles. Thus, the EXILIS causes the collagen supporting tissue to remodel, thereby stimulating and strengthening the collagen network to improve skin laxity and texture. In general, patients undergo four to six sessions, depending on how they respond.
