100 pure resveratrol is a common antioxidant widely found in over 70 different plants (e.g., grape skins, peanuts, etc.) that provides many health benefits. Guanjie follows GMP and have their products tested by third-party laboratories for purity, potency, and contaminants. These tests can confirm that the resveratrol powder is free from harmful substances and accurately labeled with its content. Several studies have demonstrated the antioxidant, anti-inflammatory and cytoprotective effects of resveratrol, which can help with skin wound healing, scarring, and combat skin (photo)aging. The research is summarized in "The impact of resveratrol on skin wound healing, scarring, and aging," a review that was published in the International Wound Journal.
Resveratrol can be an effective treatment for wound healing, reducing excessive scarring, and even preventing photoaging of the skin, according to the findings. In the future, more in vitro and in vivo evidence of resveratrol's relevant effects is still needed.
"The "French Paradox", which suggests that regular and moderate alcohol consumption may have potential health benefits, was first linked to wine polyphenols, particularly resveratrol, by Renaud and DeLogeril in 1992. Since then, the scientific community has begun to recognize resveratrol's numerous biological activities, including its antioxidant, anti-inflammatory, anti-obesity, and anti-cancer properties.
The effects of 100 pure resveratrol on wound healing, skin scarring, and photoaging
Among the multiple biological functions of resveratrol, antioxidant function is the most prominent. Resveratrol protects cells from hydrogen peroxide-induced oxidative stress and UV irradiation-induced apoptosis. This is partly attributed to the direct action of resveratrol as a free radical scavenger. Resveratrol also indirectly modulates cellular antioxidant pathways.
Additionally, resveratrol has anti-inflammatory properties that prevent inflammatory responses from occurring. This is because it can prevent arachidonic acid-like synthesis, inhibit the expression of pro-inflammatory cytokines (like IL6), and target NFkB. Additionally, resveratrol targets the signaling pathways of toll-like receptors (such as TLR2, TLR3, and TLR4). Resveratrol may inhibit NF-kB activity in animal skin models of psoriasis and reduce imiquimod-induced TLR7, TLR8, and TLR9-mediated inflammation.
100 pure resveratrol's role in wound healing
The skin's barrier function depends on wound healing, which is a complicated and tightly controlled process.Many disease processes are associated with damage to the wound healing pathway, which in turn creates chronic, non-healing wounds that cause severe discomfort to the patient. Inadequate angiogenesis, infections and chronic inflammatory responses can delay wound healing. Resveratrol is a hot topic in research. It may improve wound healing by promoting anti-inflammatory, antioxidant and angiogenic effects.
Resveratrol modulates inflammation, which in turn affects skin repair.Pastore et al. claimed that resveratrol's ability to reduce inflammation and heal wounds is more dependent on its interaction with the EGFR signaling pathway than on its antioxidant and free radical scavenging properties.
Studies conducted in vitro have demonstrated that reducing oxidative stress can protect fibroblasts. Due to its antioxidant properties, resveratrol can stabilize cell proliferation.In addition, the application of resveratrol with antioxidant activity significantly enhanced wound healing, as demonstrated by in vivo tests.
100 pure resveratrol has the potential to influence the formation of new blood vessels, and angiogenesis is another important factor in wound healing. Vascular endothelial growth factor (VEGF) is one of the most common and effective signaling proteins that stimulates angiogenesis in wounds among the known growth factors. Several studies have shown that resveratrol induces VEGF expression and regulates angiogenesis.SIRT1 is associated with the induction of angiogenesis, fibroplasia, and collagenous organization.Christovam et al. attributed the pro-angiogenic effects of resveratrol to the activation of SIRT1.SIRT1 is associated with the promotion of angiogenesis, fibroplasia, and collagenous organization. Resveratrol, as a SIRT1 activator, can have a favorable effect on wound healing.
Khanna et al. found that wound sites enriched with oxidants promote VEGF expression, which promotes wound healing. According to their study, the use of resveratrol enhanced the oxidative environment at the wound site and was associated with increased expression of VEGF and tenascin (tendon protein) at the wound edges. Another in vitro study confirmed these findings and showed that resveratrol induced VEGF expression in keratinocytes. Data from another in vivo study also identified angiogenic effects of resveratrol after long-term topical administration. The improvement in wound bed angiogenesis was attributed to stimulation of the AMPK pathway, a key mediator of wound healing.
However, Bråkenhielm et al. suggested that resveratrol may block VEGF and FGF receptor-mediated angiogenic responses and inhibit capillary endothelial cell growth, and that such antiangiogenic effects lead to delayed wound healing. Therefore, more studies using suitable in vitro and in vivo models are needed to elucidate the exact mechanisms by which resveratrol affects angiogenesis.
Resveratrol has antibacterial and antifungal properties and has shown immunostimulatory effects in wounds.Shevelev et al. showed that topical treatment with 100 pure resveratrol when wounds failed to heal had significant antimicrobial effects against important pathogens such as Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans (Candida albicans). Its antimicrobial effect appears to be superior to that of some commercial antimicrobial agents (Levomecol) and antifungal creams (Clotrimazole). Further in vitro studies showed that resveratrol directly inhibited the growth of microorganisms in a dose-dependent manner. Thus resveratrol may be a promising drug against skin infections.
Resveratrol also shows good potential in the treatment of diabetic ulcers. By activating endothelial SIRT1 and promoting FOXO1 degradation and inhibiting c-Myc expression, resveratrol prevents hyperglycemia-induced endothelial dysfunction and impaired angiogenesis. In addition, in diabetic difficult-to-heal wounds, resveratrol also helped to improve angiogenesis induced by glyoxalase I (GLO1) overexpression. In addition to IRE1α, GLO1 promotes wound healing through multiple pathways.
Anti-scarring effects of 100 pure resveratrol
Pathological scarring is a form of tissue fibrosis caused by excessive deposition of extracellular matrix (ECM) components (e.g., collagen) and an imbalance in fibroblast proliferation and apoptosis. These pathophysiologic processes are regulated by TGF-β1. Due to its fibrotic properties, TGF-β1 is one of the key factors in pathological scar formation. Currently, although several therapies are available, pathological scarring remains a major health problem due to the lack of permanent improvement or treatment-related side effects, but there is growing evidence that resveratrol has an antifibrotic effect.
At the cellular level, Zeng et al. demonstrated that 100 pure resveratrol inhibits the proliferation of human skin proliferative scar fibroblasts (HSFBs), which leads to cell cycle arrest and induces apoptosis in a dose- and time-dependent manner. The antiproliferative effect was achieved by induction of apoptosis after 24 hours of treatment with resveratrol. The longer the resveratrol was administered and the higher the concentration, the better the effect. In addition, resveratrol down-regulated the expression of type I and type III pre-collagen mRNA in HSFBs, leading to reduced collagen deposition.
A few studies have explored the genes and signaling pathways associated with pathological scar fibroblast proliferation. In this context, Zhai et al. found that resveratrol inhibited cell proliferation and induced apoptosis in HSFBs by modulating the TGF-β1/Smad signaling pathway. Resveratrol inhibited the expression of TGF-β1 and Smad-2,3,4 proteins in HSFBs, which induced an antifibrotic effect.Pang et al. demonstrated that the expression of microRNA-4654, which is involved in the regulation of cell proliferation, differentiation, apoptosis, and autophagy, was significantly down-regulated in HSFBs, compared to normal skin fibroblasts (NSFBs).
Resveratrol induced autophagy in HSFBs by downregulating the expression of brain Ras homologous protein (RHEB) and upregulating microRNA-4654. In addition to RHEB, the mammalian target of rapamycin (mTOR) signaling pathway appears to affect specific proliferative mechanisms in pathological scar formation. tang et al. 2017 found enhanced expression of mTOR and its corresponding downstream target protein ribosomal protein S6 kinase (70S6K) in HSFBs, whereas no clear expression was seen in NSFBs. Resveratrol-treated HSFBs reduced the expression of mTOR and 70S6K mRNA. Similar results regarding the relationship between the mTOR signaling pathway and resveratrol were confirmed in 2020 by Tang et al. In addition, other key elements of the mTOR signaling pathway, such as PI3K and AKT, were elevated in HSFBs. Resveratrol reduced the expression of AKT in HSFBs. microRNA-4654, TGF-β1/Smad and mTOR signaling pathways, as well as the potential molecular mechanisms underlying the effects of resveratrol modulation, may provide new avenues for potential therapeutic strategies for pathological scarring.
In addition to the above potential molecular targets for preventing or treating pathological scar formation, SIRT 1 also appears to play an important role as a drug target in fibrotic diseases. Compared with NSFBs, Bai et al. observed reduced SIRT 1 expression in HSFBs. As a SIRT1 agonist, resveratrol upregulated SIRT1 in a dose-dependent manner and downregulated collagen types I and III mRNA and α-smooth muscle actin (α-SMA) levels. In addition, as a result of SIRT-1 upregulation, resveratrol inhibited TGF-β1-induced transdifferentiation of skin fibroblasts to myofibroblasts, leading to decreased expression of fiber markers such as collagen type I, collagen type III, and α-SMA. The same group of authors also blocked SIRT-1 expression in mouse wounds by intradermal injection of a recombinant lentiviral vector (SIRT1-shRNA) that silences SIRT1 in a mouse wound model with a full-layer wound. The use of resveratrol resulted in a more ordered thinning of the collagen fiber organization compared with SIRT1-shRNA-treated mice. The results suggest that up-regulation of SIRT1 with resveratrol has a potential preventive effect on pathological scar formation in vivo.

Although a small number of in vitro and in vivo studies with various targets have shown that resveratrol improves antifibrotic properties, more animal models, particularly clinical ones, are needed to demonstrate its relevant effects. Resveratrol's antifibrotic properties have, however, not been the subject of any clinical studies to date.
100 Pure Resveratrol's photoprotective and anti-aging properties
It has been demonstrated in numerous studies to be the primary cause of skin aging. Three major skin aging cascades are triggered by prolonged UV exposure: MMP-1-mediated senescence, inflammatory senescence associated with IL6 and IL8, and apoptosis-induced senescence associated with NF-kB or caspase 3.
Resveratrol's anti-inflammatory, antioxidant and antitumor pathways are widely used to prevent photoaging. However, its specific protective mechanism against UV damage at the cellular level is not fully understood. Recently, Subedi et al. found a potential down-regulation of the above pathways by resveratrol in cells irradiated in vitro. Resveratrol and resveratrol-rich rice (RR) down-regulated UVB-induced ROS production in normal human dermal fibroblasts (NHDFs), resulting in a decrease in the expression and transcription of the inflammatory factor MMP-1, which leads to inflammatory senescence, and an increase in type I collagen expression.
Zhou et al. also found that resveratrol could achieve photoprotection by upregulating HSP27 expression. By preventing the activation of NF-kB and caspase-3, resveratrol also inhibited apoptosis. The findings demonstrated a significant increase to 94% in the survival rate of cultured human keratinocytes (the HaCaT cell line) that had been pretreated with various doses of resveratrol.
In addition, subsequent in vivo studies can utilize the findings of previous in vitro studies. Resveratrol's oral or topical administration has been shown to prevent UVB-induced epidermal thickening in recent in vivo studies with mice. MMP-1 and MMP-9 expression was decreased at the cellular level by resveratrol. Activation of the intracellular Nrf2-mediated antioxidant signaling pathway prevented UVB-induced cellular damage.Further in vivo studies on adult male Wistar rats by Abbas et al. also confirmed the photoprotective effect of topically applied resveratrol.
The potential application of resveratrol was also investigated by Moyano-Mendez et al. who found that it had a significant inhibitory effect on ROS in vitro. Resveratrol was mixed with β-cyclodextrin (βCD) as a solubilizing cofactor and tested in eight women aged 45-70 years who exhibited significant signs of photoaging (e.g., loss of skin luster, moisture, and elasticity). After 30 days of use, all subjects showed significant improvement in skin condition, with a significant reduction in signs of aging on the half of the face treated with the formula.
However, only a few further clinical studies have investigated the protective effects of 100 pure resveratrol on photoaged skin.A recent study by Farris et al. reported significant week improvements in a number of skin parameters after 12 hours of daily nightly use of a topical antioxidant containing resveratrol, baicalein, and vitamin E. The results of this study are summarized below. In addition to induction of the Nrf2 pathway and reduction of ROS, the authors were able to detect a significant increase in type II collagen α1 gene expression. This finding was supported by clinical improvements in elasticity and skin thickness measured by ultrasound.
In 2019, Igielska-Kalwat et al. verified the skin-firming and skin-moisturizing properties of resveratrol in 20 volunteers observed over a 6-week period. After 2 weeks of normal use, the test revealed a 20% increase in skin hydration. The authors stated that resveratrol inhibits transcutaneous water loss (TEWL) by replenishing and modifying the natural hydrolipidic layer and intercellular cement deep in the skin.
