This review confirms that pullulan is a safe, non-toxic sugar polymer that's already widely used in cosmetics like creams, lotions, and sunscreens. Its main appeal: it can act as a delivery system to help active ingredients penetrate different skin layers more effectively. No new efficacy data is presented—this is a summary of existing research on pullulan's properties and existing uses.

This is a literature review, not an original experiment. The authors analyzed and summarized existing published research on how pullulan has been used in pharmaceuticals and cosmetics.
