The present invention relates to a skin injection composition containing two or more crosslinked hyaluronic acid particles having different particle diameters and non-crosslinked hyaluronic acid. The skin injection composition according to the present invention has a viscosity for skin injection, an extrusion force, Also, the condition of viscoelasticity is satisfied, and the deviation of the pushing force is small, so that the user does not feel fatigue when the composition is injected into the skin. In addition, it has excellent viscoelasticity and tissue repair ability, is maintained for a long period of time, has a low initial swelling degree, has a fast recovery rate, and has excellent effects on internal safety and stability.本発明は、粒径が互いに異なる２以上の架橋ヒアルロン酸粒子及び非架橋ヒアルロン酸を含む皮膚注入用組成物に関し、本発明による皮膚注入用組成物は、皮膚注入のための粘度、押出力、及び粘弾性の条件を満たし、押出力の偏差が少なくて組成物の皮膚注入時にユーザーが疲労度を感じない。また、粘弾性及び組織修復能に優れており、持続期間が長く維持され、初期の腫れの程度が低くて回復速度が速く、体内安全性及び安定性に優れた効果がある。
