Title:

HYALURONIC ACID FILLER HAVING HIGH VISCOELASTICITY AND HIGH COHESIVENESS

Document Type and Number:

WIPO Patent Application WO/2020/009555

Kind Code:

A1

Abstract:

A hyaluronic acid filler according to the present invention shows improved high viscoelastic flow characteristics, thus exhibiting the advantages of both a monophasic hyaluronic acid filler and a biphasic hyaluronic acid filler, such that when injected into the skin, the hyaluronic acid filler can retain a shape for a long time with low mobility, thereby reducing wrinkles, and repairing or enlarging the volume of soft tissues, such as cheeks, breasts, nose, lips, and buttocks. Furthermore, the hyaluronic acid filler can be suitably used in contour correction, and even when prepared by using a small amount of a cross-linking agent during the preparation process, can increase the retention time in a human body with negligible side effects.
