There is provided a porous body which has a first surface and a second surface opposite to each other, and which comprises a first polymer material and a second polymer material, in which a Young's modulus of the first polymer material is lower than a Young's modulus of the second polymer material, an in vivo disappearance rate of the first polymer material is higher than an in vivo disappearance rate of the second polymer material, and a composition in a first region of the porous body and a composition in a second region of the porous body are different from each other.

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.
