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.

This was a literature review that analyzed existing research on multifunctional hydrogel dressings made from natural polymers, focusing on their wound-healing properties and how they're engineered using techniques like 3D printing and electrospinning.
