PromaCare 4D-PP is a product wrapped in papain. To guarantee the activity of papain in the raw material, we concord molecular degrees of freedom, distribute the relative location of papain in the product, and add sleroglucan as the sustained release skeleton. Our exclusive processing of the small core fungus glue was used to construct a sustained-release bone scaffold, which allows the papain enzyme activity to be retained for a longer and more stable duration, with improved compatibility, and added to the formula more stably and gently.
