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 present disclosure relates to a hologram recording medium having a main relaxation temperature (Tr) of 0° C. or less, wherein the Tr is a point where a rate of change of phase angle with respect to temperature is the largest in a range of −80° C. to 30° C. in dynamic mechanical analysis. The present disclosure also relates to an optical element including the same and a holographic recording method using the hologram recording medium.
