Chitosan, alginate, hyaluronic ac…d healing: A review.

This review examined alginate as a wound-healing ingredient in hydrogel dressings, particularly when combined with other natural polymers like chitosan and hyaluronic acid. Researchers found that alginate-based hydrogels show promise because they're non-toxic, biocompatible, allow oxygen through, and maintain moisture—mimicking healthy skin's natural properties. The study notes alginate works best when paired with other ingredients or loaded with active compounds, rather than used alone.
