Classification of hydrogels in skin wound healing applications

In the past, various methods were used to heal skin wounds, many of which did not have favorable results. Replacing the old methods with dressings based on hydrogel compounds has led to an increase in the quality and speed of wound healing. The role of hydrogels in improving gas exchange and oxygen supply along with absorption of wound secretions and temperature regulation and reduction of infectious agents on the wound is known. In this study, we tried to introduce the most important hydrogel groups that are effective in healing skin wounds. The results of investigations show that a wide range of these compounds include polymer hydrogels with natural bases (cellulose, starch, chitin, chitosan, carrageenan, alginate, dextran, pullulan, etc.), hydrogels produced with physical bases. and chemical (copolymer, homopolymer, etc.), combined hydrogels with natural and synthetic bases (creating complexes with chitosan, collagen, and dextran origin with compounds such as polyvinyl alcohol, etc.) and advanced hydrogels (self-healing , spraying, intelligent, etc.)
