- the powder formulation according to the present invention has the advantage of being easy to transport, store, and handle, as well as being easily dissolved in an aqueous medium at room temperature, and increasing collagen formation when introduced into the body. It was confirmed by this that it induces excellently and exhibits a more excellent tissue repair effect.
