The first, unavoidable step of the treatment (as we must not inject directly into the line) is to lift the fallen malar fat pad and the sagging skin by hyaluronic acid injections, where the lift takes place using deeply fixed points and/ or by a higher (nearer the surface) movement vector.
A moderately (more fluid) reticulated hyaluronic acid is injected if the smile line is still just a wrinkle, while a more strongly reticulated (thicker) product is used if the smile line is now a deep fold or wrinkle.
Injection is by cannula into the furrow of the line.
The product will stay in place for about a year, and it must not be forgotten that this is being put into an area with a lot of constraints (chewing, smiling).
Treating this area makes the appearance of having a ‘sad mouth’ disappear.
