The present invention relates to a composition for injection into skin, the composition containing two or more crosslinked hyaluronic acid particles having different particle diameters and non-crosslinked hyaluronic acid. The composition for injection into skin according to the present invention satisfies viscosity, extrusion force, and viscoelasticity conditions for injection into skin, and allows a user to feel no fatigue when the composition is injected into the skin, due to a small deviation of extrusion force thereof. In addition, the composition of the present invention has excellent viscoelasticity and tissue repair ability, a long sustained duration, a fast recovery rate due to a low degree of initial swelling, and excellent safety and stability in the body.
