We compared two types of moisture-retentive dressings (dressings that are capable of maintaining a moist environment) in wound healing. The conventional method of using an impregnated gauze in combination with a moist wound dressing was compared with TenderWet. First, we report results from an in vitro study and an animal experiment that included assessment of reepithelization and incidence of wound infection. Secondly, we discuss our experience using TenderWet in a clinical setting. Two cases of deep dermal burns are described and documented in detail. The results of our work suggest that a moist wound environment is more effective in facilitating wound healing than conventional methods.

Hyaluronic acid (HA)-derived hydrogels signify a noticeable development in biomedical uses, especially in cancer treatment and wound repair. Cancer continues to be one of the foremost causes of death globally, with current therapies frequently impeded by lack of specificity, serious side effects, and the emergence of resistance. HA hydrogels, characterized by their distinctive three-dimensional structure, hydrophilic nature, and biocompatibility, create an advanced platform for precise drug delivery, improving therapeutic results while minimizing systemic toxicity.

Oral ulcers are prone to recurrence and often complicated by bacterial infections. Currently, antibiotics, glucocorticoids, and anesthetics are commonly employed in clinical practice to alleviate symptoms. However, these medications exhibit limited retention in the moist and dynamic environment of the oral cavity, and their long-term use may lead to various side effects or drug resistance.

Antioxidant hydrogels that can provide a moist environment and scavenge reactive oxygen species have emerged as highly potential wound dressing materials. In situ-forming and good tissue adhesiveness will make them more desirable, as they can fill the irregular wound defect, stick to the wound, and offer intimate contact with the wound. Herein, a hydrogel dressing combining in situ-forming, good tissue adhesiveness, and excellent antioxidant capabilities was developed by simply conjugating dopamine onto carboxymethyl chitosan.

Natural hydrogels have garnered increasing attention due to their natural origins and beneficial roles in wound healing. Hydrogel water-retaining capacity and excellent biocompatibility create an ideal moist environment for wound healing, thereby enhancing cell proliferation and tissue regeneration. For this reason, naturally derived hydrogels formulated from biomaterials such as chitosan, alginate, gelatin, and fibroin are highly promising due to their biodegradability and low immunogenic responses.

After endoscopic sinus surgery (ESS), nasal packing is often used to stop bleeding and promote wound healing. Because maintaining a moist environment is important to enhance wound healing, hydrogel-based wound dressings are effective to promote wound healing. Chitosan is used in the medical field because of its high hemostatic and wound healing properties.
