Lip filler is an effective way to add volume and definition to the lips, with instant results. At Cavendish Clinic, our expert Aesthetic Doctors work with your individual features to provide subtle, natural-looking lip augmentation. Dermal filler for the lips is made from hyaluronic acid, a substance that occurs naturally in the human body and has hydrating properties because it attracts and retains water. The loss of hyaluronic acid as we age leads to the appearance of wrinkles and the loss of fullness to our lips. Our lips become thinner, lose volume, and lack definition. It’s often most noticeable around the “cupids bow”, however, we can develop vertical, or “marionette”, lines around the mouth, which can form at the corners going down to the chin or we can even develop a droop to the corners of the mouth, giving your lips a sad appearance.
