Abstract: The present invention relates to a novel dermal filler composition and a method for preparing the same. Even though the composition of the present invention comprises, as a main component, only cross-linked dextran having the molecular weight of 30,000 to 100,000, the composition can rapidly augment a detective area of the skin and maintain softness to the touch even, the composition eliminates the necessity of a pretreatment, such as an allergy test, which might otherwise be required prior to injection, is inexpensive, and is not easily decomposed or absorbed in vivo, thereby stably maintaining the tissue-volume augmentation effects after injection over a long period of time.
