Re-modeling is the fourth and final phase of wound healing. In this stage, the ECM of the wounded tissue is reconstituted to be similar to healthy tissue. This phase is mostly regulated by differentiated myofibroblasts. Collagen, the main ECM component, is synthesized and accumulates in the granulation tissue to restore the tensile strength and elasticity that is found in normal skin tissue [ 7]. During this stage, many of the newly produced capillaries regress, and the vascular density of the wound is restored [ 3, 8]. The proliferative process is triggered by an environment of low wound pH, reduced PaO 2 and increased lactate (due to reduced blood supply to the wound). A moist healing environment has been clinically proven to aid and speed up the natural wound healing process. Elastoplast Wound Healing Ointment creates a breathable film that protects the wound from external influences while preventing the wound from drying out. This is clinically proven to promote faster wound healing and reduce the risk of scarring. Turmeric is a spice that comes from the plant of the same name. It contains curcumin, which has antibacterial, antifungal, and anti-inflammatory properties.

Within the first few days no significant difference in angiogenesis score was observed amongst the groups (Fig. ​ (Fig.6a1-a4, 6a1-a4, 6d). However, AM and AM+AV gel treated skin were shown to have appearance of more neo-vascularization (Fig. ​ (Fig.6a5-a20) 6a5-a20) with time. On the 12th day post burning, all treated groups appeared to have induced neo-epithelialization, in contrast to the control (Fig. ​ (Fig.6a5-a8, 6a5-a8, 6b). At day 18, neo-epithelization was clearly visible with incomplete epidermal and dermal layer (Fig. ​ (Fig.6a9-a12, 6a9-a12, 6b).

Increase the oxygen concentration in blood in the wound area and shortens the wound healing process People often use OTC antibacterial ointments for minor wounds, but they may not be necessary. A person may use petroleum jelly, which acts as a barrier to protect the wound beyond a waterproof bandage. 2. Aloe vera Slower degradation of the dextran hydrogel with the high content of nondegradable PEGDA and higher cross-linking densityProliferation is the third phase of wound healing. In this phase, granulated tissue with an extracellular matrix (ECM) composed of new connective tissue and blood vessels is formed in the presence of an appropriate amount of moisture and oxygen. The movement of T-lymphocytes (T-cells) into a wound bed plays an important role in granulated tissue formation. These T-cells secrete biomolecules, such as fibroblast growth factor 7 (FGF-7), keratinocyte growth factors (KGFs), and insulin-like growth factor-1 (IGF-1), to regulate fibroblast and keratinocyte expansion during this stage [ 6]. The team of researchers are furthering their research to finetune the effectiveness of the magnetic wound-healing gel and are testing the gel’s effectiveness on the tissue of people with diabetes. Contraction occurs in the context of open wounds to assist the healing process, as it results in a smaller deficit to be filled with connective tissue. The underlying process of contraction is still poorly understood, but it likely involves c ontractile forces generated by fibroblasts within the wound. Wound contraction Poljšak, N., et al. (2020).

Advanced Materials. 2023:2304638. doi: 10.1002/adma.202304638 A 2016 review states that laboratory research suggests honey significantly improves the healing rate of wounds in animals. It also says that it reduced scar formation and inhibited bacterial growth in acute wounds and burns.

He explained: “They merely prevent the wound from worsening and patients need to be scheduled for dressing change every two or three days. It is a huge cost to our healthcare system and an inconvenience to patients.” Hekmatpou, D., et al. (2019) .

In another study, a dual-responsive hydrogel against pH and ROS was designed to provide a dressing with sustained delivery of anti-inflammatory (nimesulide (NIM)) and antimicrobial (silver nanoclusters (VAN-AgNCs)) agents to the wound area [ 129]. This hydrogel was generated by crosslinking 3-carboxy-phenylboronic grafted gelatin with PVA. VAN-AgNCs was directly incorporated into the hydrogel while NIM was loaded in pH-sensitive micelles before being encapsulated into the hybrid hydrogels. Upon increased acidity or ROS levels in the wound environment, this hybrid hydrogel disintegrated and released the encapsulated VAN-AgNCs and micelles. The acidic environment further disintegrated the micelles to release NIM. VAN-AgNCs displayed effective antimicrobial activity while NIM exhibited an anti-inflammatory effect in both in vitro and in vivo experiments. In another study, a thermosensitive hybrid hydrogel was developed for the controlled release of MMP-9 siRNA to silence the MMP-9 gene [ 64]. MMP-9 is a matrix metalloproteinase displaying an important role in tissue remodeling. The excessive activation of MMP-9 causes degradation of local ECM which disrupts the cell migration and negatively affects the healing of diabetic wounds. Controlled release of MMP-9 siRNA from the thermosensitive hybrid hydrogels enabled down-regulation of the MMP-9 expression and improved the wound closure in a diabetic rat model. AgNPs release showed rapid antibacterial activity and simultaneous deferoxamine release promoted angiogenesis by enhancing the expression of hypoxia-inducible factor-1 alpha (HIF-1α) and VEGF Chronic wounds influence quality of life and present an economic burden because of prolonged treatment periods. The effects of various factors, such as pressure, ischemia, inflammation, and stress, can cause delayed healing. Different methods, such as debridement, hyperbaric oxygen therapy, ultrasound and electromagnetic therapy, negative pressure wound therapy, and skin grafts, have been used to treat chronic wounds. Each method exhibits its own advantages and disadvantages. Debridement significantly improves wound healing by shortening healing times. Hyperbaric oxygen therapy is expensive, and its use is limited to diabetic foot ulcers. Ultrasound and electromagnetic therapy can be used for venous and pressure ulcers and surgical incisions. However, these therapies might superficially damage or burn the endothelial tissues if proper parameters are not used. Negative pressure wound therapy limits patient mobility. In addition, excessive noise during treatment causes patient discomfort. Skin grafts are more expensive than other methods and require sophisticated procedures. All of the aforementioned techniques require clinical specialists with fully equipped health facilities. When an injury occurs, the initial phase is always an outpouring of lymphatic fluid and blood. It is during this process that adequate hemostasis is achieved. Both the extrinsic and intrinsic coagulation pathways are activated and play a role in stopping blood loss. Aggregation of platelets follows the arterial vasoconstriction to the damaged endothelial lining. A release of adenosine 5´ diphosphate (ADP) results in the clumping of platelets and initiates the process of thrombosis. This vasoconstriction is a short-lived process that is soon followed by vasodilation, which allows the influx of white cells and more thrombocytes. Elastoplast Wound Healing Ointment can be used at any stage of the healing process on superficial open wounds and damaged skin.Macroscopic evaluation of wound closure and quantitative measurement of wound contraction and re-epithelialization Col makes up the major component of the extracellular matrix (ECM) in humans [ 4] while gelatin is a Col derivative [ 12]. Col is a perfectly organized structure as a three-dimensional (3D) scaffold that surrounds the cells. Thus, it has a dominant influence in maintaining the structural and biological integrity of the ECM. Being a natural component of the human body, it has been categorized as one of the major biomaterials widely used in wound healing [ 4]. Nonetheless, the physicochemical properties of Col and gelatin greatly influence the mechanism of skin wound healing. Methacrylate-modified chitosan (CS-GMA) and Arg-PEUU hybrid hydrogels exhibited an excellent antibacterial activity
