HYALURONIC ACID FILLER HAVING HIGH LIFT CAPACITY AND LOW INJECTION FORCE

WIPO Patent Application WO/2020/013580

A1

A hyaluronic acid filler according to the present invention not only exhibits an improved high lift capacity so as to maintain the shape of the skin for a long period of time while having a low probability for movement when injected into the skin, but also has a very low injection pressure during injection so as to reduce wrinkles and restore or expand the volume of soft tissues such as that of the cheeks, breasts, nose, lips, and buttocks, and is excellent when used for contour correction. Even when crosslinking agents are used sparingly in the manufacturing process, the hyaluronic acid filler has increased residence time in the human body and causes patients less pain.
