Projection capacity assessment of hyaluronic acid fillers

Abstract

Aim: Hyaluronic acid (HA) is considered as the gold standard biomaterial for facial soft tissue correction. Over the last 8 years, there has been a strong demand from physicians for HA products with high projection capacity to restore facial volume loss at the level of the cheeks, cheekbones, chin, temples and jawlines. The projection capacity is thus an essential property for HA fillers especially for the products dedicated to the restoration of the volume of the face.
