The BTL Exilis System treatment is ideal for any patient between the ages of 25 and 70+ looking for cosmetic improvement on their face and body. BTL Exilis System is ideal for treating wrinkles and fat. Common areas of treatment include the eye area, around the mouth, chin area, jaw line, décolleté, but any area including the arms, legs, knees, ankles, buttocks, abdomen and love handles can be treated. We all have areas of fat that we just assume is our burden to carry, but Exilis can attack those stubborn areas with a focus on fat or collagen by controlling the surface temperature and depth of RF delivery.
