A syringe for self dermal rejuvenation is disclosed. The syringe for self dermal rejuvenation includes a liquid syringe and an injection member. The liquid syringe includes a cylinder filled with liquid, a piston inserted into the cylinder from the top of the cylinder, a discharge portion formed on a lower end of the cylinder, and a thread formed around the discharge portion. The injection member includes a cylindrical body part, an inlet portion formed on an upper end of the body part to be coupled to the discharge portion as the discharge portion is inserted into the inlet portion, and a coupling portion formed around the inlet portion to be coupled to the thread. When a user turns the coupling portion to couple the coupling portion to the thread, the injection member is fastened with the liquid syringe. Liquid is injected into the injection member from an upper end of the body part through the liquid syringe. An inlet check valve is provided on one side of a lower end of the injection member such that gas can be injected into the injection member from the lower end through the inlet check valve. A needle is coupled to a lower end of the injection member such that gas or liquid stored in the body part can be discharged to the outside.COPYRIGHT KIPO 2015실린더 내부에 액체가 채워지고 실린더 상단에 피스톤이 삽입되며 실린더 하단에 토출부가 형성되고, 토출부의 주변으로 나사산이 형성된 액체주사기 및 원통형의 몸체부가 구비되고 몸체부의 상단에 토출부와 상호 삽입 결합되는 유입부가 형성되며 유입부의 주변에 나사산과 결합되는 결합부가 형성되어 나사산과 결합부가 돌려끼워짐으로써 액체주사기와 체결되고 액체주사기를 통해 몸체부 상단부에 액체가 주입되며, 하단부에는 일측으로 유입체크밸브가 마련되어 유입체크밸브를 통해 하단부에 기체가 주입되고, 하단에는 바늘이 결합되어 몸체부의 기체 또는 액체가 외부로 유출되도록 하는 주입부재를 포함하는 자가 진피 재생용 주사 기구가 소개된다.
