The present invention relates to hydrogel particles coated with lipid, which are made from dispersing hydrogel particles in an organic solvent in which lipids are dissolved, and to a method for manufacturing same. Unlike the existing method for manufacturing hydrogel core vesicles, the present invention can effectively manufacture same by using an emulsification method, without involving the steps of chemical treatment of the surface of hydrogels or dilution, thereby facilitating mass production and preventing the decrease of drug encapsulation efficiency. The present method could be widely used for research on delivery carriers of oil/water-soluble active material or cell structure reproduction and more particularly, a keratinocyte mimetic of the present invention containing natural moisturizing factors can contain a large quantity of bound water for a long time, thereby exhibiting superior capability to retain moisture and moisturize, and providing a composition for an ingredient in cosmetics for moisturizing.
