The present invention relates to an injection composition for a plastic surgery filler, containing porous biodegradable fine particles and a water-soluble natural polymer. The injection composition for a plastic surgery filler, according to the present invention, has an effect of remarkably improving tissue repair capacity and collagen content according to the combination, under optimal conditions, of 1) the amount of porous biodegradable fine particles, 2) the crosslinking rate of hyaluronic acid, and 3) the mixing concentrations of crosslinked hyaluronic acid and purified water.La présente invention concerne une composition dinjection pour une charge de chirurgie plastique, contenant des particules fines poreuses biodégradables et un polymère naturel soluble dans leau. La composition dinjection pour une charge de chirurgie plastique, selon la présente invention, présente un remarquable effet damélioration de la capacité de réparation des tissus et de la teneur en collagène selon la combinaison, dans des conditions optimales, 1)de la quantité de particules fines poreuses biodégradables, 2) du taux de réticulation de lacide hyaluronique, et 3) des concentrations de mélange dacide hyaluronique réticulé et deau purifiée.본 발명은 다공성의 생분해성 미세입자 및 수용성 천연고분자를 포함하는 성형 필러용 주사제 조성물에 관한 것으로, 본 발명에 따른 성형 필러용 주사제 조성물은 1)다공성의 생분해성 미세입자의 함량, 2)히알루론산의 가교율, 3)가교 히알루론산 및 정제수의 혼합 농도를 최적 조건으로 조합함에 따라서, 조직수복력 및 콜라겐 함량이 현저히 향상되는 효과가 있다.
