Abstract: [Summary]
The present invention has a special filling (WIE) property parameter value developed using microrheology technology, and thus exhibits improved high viscoelasticity flow properties, has low mobility when injected into skin whilst still maintaining the shape thereof, and thus has excellent soft tissue restoration properties, for example for the cheeks, breasts, nose, lips or bottom, and excellent volume expansion and wrinkle alleviation properties.

Abstract: The hyaluronic acid filler according to the present invention shows improved high lift capability, and thereby not only can maintain its shape for a long time while it is unlikely to move when injected into skin, but also the injection force during injection is very low, and therefore it is excellent in anti-wrinkle, soft-tissue augmentation such as cheeks, breast, nose, lips and hips, and the like or expansion of its volume, and contour correction, and even if a crosslinking agent is used at a small amount in the preparation process, the duration in the human body is increased because of efficient crosslinking reaction and pain of patients is caused less by the reduced injection force.

Abstract: The hyaluronic acid filler according to the present invention exhibits improved high viscoelastic flow characteristics, and has advantages of monophasic hyaluronic acid fillers and biphasic hyaluronic acid fillers together, and therefore it maintains the shape while having low moving possibility when injecting into skin, and thus it is excellent when used for improving wrinkles, augmentation of soft tissues such as cheeks, breast, nose, lips and hips, etc., and correcting contours, and the duration time in the human body is increased and side effects are small, even if a small amount of crosslinking agent is used during the preparation process.
