The present invention relates to a novel dermal filler composition and to a method for preparing same. The composition of the present invention comprises, as a main component, cross-linked dextran, the molecular weight of which is 30,000 to 100,000. The composition can rapidly augment a defective area of the skin and maintain softness to the touch even when used alone. 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 maintaining the tissue-volume augmentation effects thereof over a long period of time after injection. Therefore, the composition is suitable for use in a procedure such as penile augmentation or the like which requires the injection of a large amount of dermal filler, i.e. more than 20 cc. The composition of the present invention can be prepared through a simplified process to make the composition easily usable. The composition is sof
