The present invention relates to a composition for dermal injection which includes two or more types of cross-linked hyaluronic acid particles having different particle diameters and non-cross-linked hyaluronic acid. The composition for dermal injection according to the present invention satisfies viscosity, extrusion force, and viscoelasticity conditions for dermal injection, and an extrusion force deviation is low so that the user does not feel fatigue when the composition is injected into the dermal thereof. Also, the composition is excellent in viscoelasticity and tissue restoring ability, is maintained for a long period of time, allows rapid recovery because an initial swelling degree is low, and also is excellent in safety and stability in the body.

A method includes forming a scaffold and seeding the scaffold with live cells; growing the cells in the scaffold; and 3D printing the cells into a living subject, where the cells continue to live in the living subject.
