Abstract:

Hyaluronic acid (HA) is the most-abundant glycosaminoglycan in the human body and it is made by repetitive sequences of D-Glucuronic Acid + N-Acetyl D-Glucosamine. Indeed, HA represents 15% of body weight in individuals weighing around 70Kg; skin represents 50% of total HA in the body; and 1/3 of total HA in the human body is metabolized daily. HA-based aesthetic dermal filler has 400-6,000 KDa of molecular weight and presents a high hygroscopic function for extracellular matrix (increases immediately in 15% its volume). Based on the short 12-hour half-life of a noncross linked HA-based filler, scientists created cross linked HA-based fillers that have better stability against metalloproteinase and a long-lasting durability. However, such manufacture profile impacts directly on the HA-based product rheological properties (rheology is the study of the flow of matter of a product, under external conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force). In this lecture, the speaker will explore the different rheological properties of different commercial HA-based fillers, based on they manufacture process.
