  • Method to prepare a filler with hyaluronic acid base comprising a neutralization step
    Patent number: 11534385
    Abstract: The present invention concerns a method to prepare a filler with a hyaluronic acid, which has improved properties of chemical-physical stability over time and optimal viscosity for cutaneous injection. In particular the method comprises a first step in which the hyaluronic acid is crosslinked, and a subsequent step for the neutralization and hydration of the crosslinked hyaluronic acid.
