The present invention relates to a hydrogel composition and to a method for manufacturing a hydrogel using same. The hydrogel composition comprises 0.1 to 10 wt% of a cross-linking agent, 0.2 to 6 wt% of a gelling polymer, 0.5 to 20 wt% of a polyhydric alcohol, and 70 to 90 wt% of purified water. The shape of the hydrogel may be retained without a supporter. The hydrogel may not be untied but may be stable even when impregnated into cosmetics or pharmaceuticals. In addition, the cosmetics or the pharmaceuticals may be delivered uniformly to the skin.
