TY - JOUR AU - AB - Aim: Skin firmness is one of the key parameters to define skin quality and facial aging. Among the minimally invasive anti-aging strategies, hyaluronic acid (HA) injection is widely accepted to improve skin quality. While most of the available HA injectables are designed and intended for intradermal injection, a novel HA/sorbitol composition containing 2.6% high molecular weight hyaluronic acid stabilized by sorbitol was recently developed to be specifically injected into the adipose tissue to improve the quality of all skin layers, especially the skin firmness. Methods: The HA/sorbitol composition was investigated versus product comparators in terms of biophysical properties, tolerance in subcutaneous tissue with in vivo implantation study, and skin firmness assessment on human skin explants. Results: The HA/sorbitol composition was characterized by unique and differentiated biophysical properties, proper distribution and high tolerance of the gel composition into the adipose tissue, and the ability to efficiently improve skin firmness. © The Author(s) 2022.
