The Role of Antioxidants on Wound Healing: A Review of the Current Evidence

Abstract

(1) Background: Reactive oxygen species (ROS) play a crucial role in the preparation of the normal wound healing response. Therefore, a correct balance between low or high levels of ROS is essential. Antioxidant dressings that regulate this balance are a target for new therapies. The purpose of this review is to identify the compounds with antioxidant properties that have been tested for wound healing and to summarize the available evidence on their effects. (2) Methods: A literature search was conducted and included any study that evaluated the effects or mechanisms of antioxidants in the healing process (in vitro, animal models or human studies). (3) Results: Seven compounds with antioxidant activity were identified (Curcumin, N-acetyl cysteine, Chitosan, Gallic Acid, Edaravone, Crocin, Safranal and Quercetin) and 46 studies reporting the effects on the healing process of these antioxidants compounds were included. (4) Conclusions: this review offers a map of the research on some of the antioxidant compounds with potential for use as wound therapies and basic research on redox balance and oxidative stress in the healing process. Curcumin, NAC, quercetin and chitosan are the antioxidant compounds that shown some initial evidence of efficacy, but more research in human is needed.

HPLC/MSn Profiling and Healing Activity of a Muco-Adhesive Formula of Salvadora persica against Acetic Acid-Induced Oral Ulcer in Rats

“…Farag et al (2018) examined the antioxidant activities of S. persica ethanol extract and some isolated compounds called persicaline [ 66 ]. Essentially, antioxidants have been reported to play an important role in expediting wound healing by reducing oral mucosa inflammation, thus decreasing the risk of developing precancerous lesions [ 67 ]. This provides further insight into the healing properties of S. persica .…”

Epigallocatechin Gallate: The Emerging Wound Healing Potential of Multifunctional Biomaterials for Future Precision Medicine Treatment Strategies

“…ROS and its corresponding pro-inflammatory cell signalling hold a vital role in wound healing [23,24] (Figure 3). Exogenic antioxidants are emitted as soon as the overflow of oxidative stress coerces the endogenic antioxidants, permitting inhibition of the inflammatory pathway that leads to the acceleration of wound healing due to the ROS balance [25].…”

Ceriporia lacerata Mycelium Culture Medium as a Novel Anti-Aging Microbial Material for Cosmeceutical Application

“…ROS-mediated oxidative stress weakens the dermal structural and mechanical integrity of a tissue microenvironment that contributes to age-related skin disorders, such as delayed wound healing [31,32]. To investigate the effect of CLEPS on the wound recovery process, HaCaT cells were grown in a low serum medium (1%) (serum starvation) for 0-48 h at 37 • C. During wound healing assays, cells not only migrate with that gap, but they also multiply.…”
