Wrinkles, fine lines, skin laxity and loss of volume and firmness are signs of aging caused by constant muscle movements, changes in the facial structure and loss of collagen and fat in the face. Injecting Botox or Dysport in the facial muscles temporarily relaxes these muscles which soften and prevents the formation of wrinkles for up to 4 months. Dermal fillers compensate for the loss of volume caused by collagen and fat loss, and can be injected in the cheeks, lips, nasolabial folds and marionette lines. Most fillers last up to one year and others last up to two years, delivering firmness, plumpness and a lift for a younger-looking appearance.
