Facial dermal filling consists in the filling of wrinkles, depressions, sulcus and scars. These are minimally invasive methods that provide safe immediate results, allowing the patient to return to daily activities straight after treatment.
There are several types of materials used as fillers. Currently, hyaluronic acid has become the material of choice because of its biocompatibility and safety profile. It exists naturally in the body and is responsible for maintaining skin hydration and preserving tissue volume. As hyaluronic acid is a highly biocompatible product, present in our organism, it is well tolerated and therefore does not generate product rejection reactions. Hyaluronic acid fillers exist at different concentrations/densities, which allow to adjust the volume injected according to the desired final result.
These fillers are commonly applied in the nasolabial folds (Chinese moustache, marionette lines) and the glabella (wrinkles or static furrows between the eyebrows), the cheekbones and the orbital rim.
Regarding the application of the filler, this is done using a syringe and fine needle after local anesthesia (normally topical cream but in certain cases with infiltration).
The onset of action is immediate. However, after application, some finishing touches can be made after 15 days. The duration of the effect produced by the hyaluronic acid varies depending on the type of skin, place applied, age and life style of the patient, as well as product brand. The effect generally lasts from 6 months to 2 years.
