What is Zinc Oxide?
Zinc is a trace element very abundant in the body. While it is known that zinc deficiency can cause delayed wound healing, the actual role of zinc in wound healing was not known. A number of experimental studies and clinical trials have been conducted using zinc. Results showed that topical zinc oxide had increased wound healing, increased reepithelialization, decreased rates of infection and decreased rates of deterioration of ulcers. Topical zinc oxide has shown to improve the rate of wound healing in patients, regardless of their zinc status. Oral zinc supplementation in zinc deficient patients did not have the same effect.

Results showed that topical zinc oxide had increased wound healing, increased reepithelialization, decreased rates of infection and decreased rates of deterioration of ulcers. Topical zinc oxide has shown to improve the rate of wound healing in patients, regardless of their zinc status.
Does zinc sulfate help wound healing?
The animal studies reviewed showed that zinc sulfate did not enhance wound healing, but delayed it. One of the major roles for zinc in wound healing was found that zinc oxide enhances the ability of matrix metalloproteinases (MMPs) to enzymatically break down collagen fragments.
How long does zinc oxide treatment last?
Studies have found that treating damaged, dry or wounded skin with zinc oxide products for just 48-hours (including during post-operative treatment) helps skin to heal better, inflammation/redness to be lowered, pigment to be restored, and interstitial fluid and sebum (oil) to be better regulated.
How to use zinc oxide cream?
Zinc Oxide Creams or Ointments: Cream is best for treating minor, non-infected scrapes and burns. You can use a bandage on top of zinc oxide cream or leave the cream exposed to air to dry. Always wash your hands and the area you’ll apply zinc oxide cream to before starting the application. Zinc oxide cream is for external/topical use only, so be careful not to swallow any or to get it into your eyes, ears or mouth. Apply zinc oxide cream directly to the affected area, including skin suffering from a diaper rash, redness, chafing, burns, poison ivy or skin irritation.
What Is Zinc Oxide?
As you probably guessed, zinc oxide is made from zinc, a type of metallic element found in nature that is now used in many different electronic, chemical and household products. Just like other elemental metals, including iron or electrolytes like magnesium, zinc is able to carry a certain electric charge that gives it special benefits within the body.

The Many Benefits of Zinc Oxide in Wound Care
Zinc oxide offers a ton of different benefits when it comes to skincare. Its healing qualities make it a common part of wound care and skin development. Here are just a few benefits of using products that feature zinc oxide:
Wound Dressing and Zinc Oxide
Dressing any type of wound can be a delicate situation. The patient needs a dressing that will help repair the damaged skin as well as an adhesive that ensures the dressing will stay in place comfortably. A zinc oxide-based adhesive can be exceptionally useful in these situations.
What is the role of zinc in wound healing?
Successful wound repair requires a series of tightly coordinated steps including coagulation, inflammation, angiogenesis, new tissue formation and extracellular matrix remodelling. Zinc is an essential trace element (micronutrient) which plays important roles in human physiology. Zinc is a cofactor for many metalloenzymes required for cell membrane repair, cell proliferation, growth and immune system function. The pathological effects of zinc deficiency include the occurrence of skin lesions, growth retardation, impaired immune function and compromised would healing. Here, we discuss investigations on the cellular and molecular mechanisms of zinc in modulating the wound healing process . Knowledge gained from this body of research will help to translate these findings into future clinical management of wound healing.
How does zinc affect wound healing?
Over the years zinc has been shown capable of modulating both innate and adaptive immune functions. Zinc alters immune responses in a multitude of ways ranging from myeloid-derived cells and inflammatory signalling to lymphocyte differentiation and antibody production. The ability of zinc to regulate immune homeostasis is a burgeoning field of study and has been extensively reviewed by others [23]. Here, we discuss the contributions of zinc within the wound repair processes with an emphasis on platelet cells and haemostasis, inflammation and host defence, granulation and re-epithelization, ECM remodelling via regulation of matrix metalloproteinases (MMPs) and its association with tripartite motif (TRIM) family proteins in membrane repair and wound healing [43,44]. By identifying roles by which zinc coordinates wound healing, we hope to stimulate further research in tissue repair and regeneration.
What are the effects of zinc deficiency?
The pathological effects of zinc deficiency include the occurrence of skin lesions, growth retardation, impaired immune function and compromised would healing.
Why is zinc important for human health?
It is important for human health and disease due to its critical roles in growth and development, bone metabolism, the central nervous system, immune function and wound healing [2]. Zinc is a vital cofactor for the function of more than 10% of proteins encoded by the human genome (~3000 proteins/enzymes) [3,4].
Is zinc in skin?
Zinc is especially important in skin [30]. Skin contains a relatively high (about 5% of body content) zinc content, primarily associated within the epidermis (50–70 μg/g dry weight) [31]. Due to its abundance in the epidermis, mild zinc deficiency is noted to lead to roughened skin and impaired wound healing [32].
Is zinc a divalent cation?
Low concentration of zinc is found intra cellularly across all tissues as a divalent cation incapable of passive diffusion across cell membranes. As such, the cellular homeostasis and bioavailability of zinc is tightly controlled through transcriptional regulation, ion transporters and compartmental stores [10,11,12,13]. Metabolically active, labile zinc is present inside cells at pico- to nanomolar concentrations with extracellular concentrations in the sub-micromolar to micromolar range [14]. The zinc transporter protein (ZIP) family zinc uptake/transporter proteins, particularly ZIP4, are responsible for zinc uptake from the extracellular milieu or intracellular vesicles [15]. Cytosolic free zinc ions have recently been identified as secondary messengers, similar to calcium ion transients, capable of interacting with target proteins in order to regulate many signal transduction pathways [16,17]. In this regard, zinc availability and regulation constitute an important component in cell physiology.
Does zinc affect cytokine production?
Macrophages and other immune cells, are major producers of cytokines. Many studies have shown that zinc modulation has an effect on cytokine production. Some of the major regulators of inflammatory cytokine production are T cell receptor (TLR) proteins. TLR proteins are capable of recognizing pathogen-specific molecular motifs and implement signalling cascades. Closely associated with TLRs is nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signalling. NF-κB is a potent transcriptional regulator involved in a plethora of cellular processes associated with wound healing including: inflammatory response, tissue remodelling, proliferation, apoptosis, cell adhesion, etc. [71]. Numerous reports have detailed the effects of zinc on TLR/NF-κB mediated inflammatory signalling, however studies have come to conflicting conclusions. Hasse et al. reported that lipopolysaccharide (LPS)/TLR4 mediated NF-κB signalling is dependent upon intracellular free zinc [72]. In their study sequestration of zinc via an intracellular membrane-permeable zinc ion chelator, TPEN (N,N,N′,N′-tetrakis(2-pyridinylmethyl)-1,2-ethanediamine), completely abolishes NF-κB activation after LPS stimulus. In contrast, there is a growing body of evidence that zinc acts as an inhibitor of TLR/NF-κB signalling. Reports have shown that zinc is capable of negatively regulating NF-κB signalling via PPAR-α, A20, IκB kinase-β (IKKβ) and phosphodiesterase (PDE) [73,74,75,76].
