Hyaluronic acid is used to lift fallen malarial tissue over time because it is responsible for the appearance of these folds.
So do not directly inject the folds to avoid weighing down the face.
If after the lift step the fold persists, it is injected.
Depending on the severity of fold, a moderately reticulated Retylane type hyaluronic acid or a strongly reticulated Restylane Perlane type acid will be used. The injection is administered to the fold, and in an imaginary triangle placed under the labial commissure to give support to the edges of the lips, and to gently lift them.
The product stays in place between eight months and two years, depending on the severity of the fold, the age of the patient and the product used.
