Abstract
The growing world's population and the increase of underlying diseases such as diabetes have caused the increasing trend of skin damage and imposed high costs on the healthcare system. The complexity and multi-step wound healing process highlights the importance of introducing efficient products to treat skin injuries effectively. Therefore, it is necessary to introduce new wound healing products to treat these types of injuries effectively. The modern wound dressings have received many attentions during recent years. These dressings facilitate skin regeneration by providing suitable physical and biological conditions. Wound dressings are produced in sponge, fibrous, hydrogel, film, and powder forms to treat different wounds. Various natural and synthetic biomaterials have been used to make these products, among which hyaluronic acid (HA) is particularly important due to its unique biological properties. As one of the main constituents of the skin's extracellular matrix, this substance is directly effective in the four stages of wound healing. These biological characteristics and high hydrophilicity have given special attention to this material as a promising option for repairing skin damage. In this article, the wound healing process is explained after describing the skin structure and types of wounds. Then, traditional and commercial dressings and their types are introduced. In the following, after introducing the most common biological materials used to make wound dressings, the structure of HA, the mechanism of degradation, and the role of this material in the different stages of wound healing are described in detail. Also, different types of HA-based wound dressings in the literature are discussed. Finally, types of commercial wound dressings based on this polymer are introduced, and an overview of the global market of wound dressings is provided to outline the perspective of the consumption of these products.
