Filling in the infraorbitary region using Perfectha Subskin® hyaluronic acid

Abstract

Hyaluronic acid (HA) is the safest substance used in dermal fillers, being well tolerated, and promoting good aesthetic results and with rare serious adverse effects. The filling of the infraorbital region presents challenges mainly related to the anatomy of the region, therefore, choosing the correct product is very important for the treatment to be effective. The aim of this study was to report a clinical case of treatment of dark circles with HA by Perfectha Subskin® brand. After anesthesia, the product was applied in a deep plane (supraperiosteal) with the aid of a cannula and in a retrograde manner. There was an immediate improvement of the volume deficiency in the region and the patient was satisfied with the result. The type of HA chosen is dense, with less connection with water and it has larger molecules compared to other types of HA, which gives a greater volumizing effect, greater resistance to enzymatic degradation and longer-lasting results with a smaller amount of product. Another characteristic of this HA is the presence of a polymer in its composition that acts as a lubricating agent, allowing the product to pass through the needle more fluidly and facilitating the product application process. The literature states that the duration of the effect obtained can reach 18 months, this duration is directly related mainly to the particle size, HA concentration and crosslinking of the product.
