Curcumin and your skin

Inflammation, aging, oxidative damage, cellulite

Curcumin, found in turmeric (curcuma longa), is one of the most widely researched natural actives known today, with potent anti-ageing, antioxidant, skin lightening, anti-inflammatory and lipolytic activity.

 

Curcumin cream

For all these reasons, curcumin is of great importance as an active ingredient in anti-ageing, anti-cellulite, leg wellness, contouring, skin whitening and under-eye creams [the Celluence® creams are the only cellulite creams in the world with high concentrations of 95%+ pure, high availability curcumin, plus 39x other natural anti-cellulite actives].

Immune Modulation by Curcumin: The Role of Interleukin-10.

Abstract: Cytokines are small secreted proteins released by different types of cells with specific effects on cellular signaling and communication via binding to their receptors on the cell surface. IL-10 is known to be a pleiotropic and potent anti-inflammatory and immunosuppressive cytokine that is produced by both innate and adaptive immunity cells including dendritic cells, macrophages, mast cells, natural killer cells, eosinophils, neutrophils, B cells, CD8(+) T cells, and TH1, TH2, and TH17 and regulatory T cells. Both direct and indirect activation of the stress axis promotes IL-10 secretion. IL-10 deregulation plays a role in the development of a large number of inflammatory diseases such as neuropathic pain, Parkinson's disease, Alzheimer's disease, osteoarthritis, rheumatoid arthritis, psoriasis, systemic lupus erythematosus, type 1 diabetes, inflammatory bowel disease, and allergy. Curcumin is a natural anti-inflammatory compound able to induce the expression and production of IL-10 and enhancing its action on a large number of tissues. In vitro and in pre-clinical models curcumin is able to modulate the disease pathophysiology of conditions such as pain and neurodegenerative diseases, bowel inflammation, and allergy, but also of infections and cancer through its effect on IL-10 secretion. In humans, at least one part of the positive effects of curcumin on health could be related to its ability to enhance IL-10 -mediated effects.

 

 

8/ Phytochemicals in regulating fatty acid β-oxidation: Potential underlying mechanisms and their involvement in obesity and weight loss.

Abstract: Excessive accumulation of fat as the result of more energy intake and less energy expenditure is known as obesity. Lipids are essential components in the human body and are vital for maintaining homeostasis and physiological as well as cellular metabolism. Fatty acid synthesis and catabolism (by fatty acid oxidation) are normal part of basic fuel metabolism in animals. Fatty acids are degraded in the mitochondria by a biochemical process called β-oxidation in which two-carbon fragments are produced in each cycle. The increase in fatty acid β-oxidation is negatively correlated with body mass index. Although healthy life style, avoiding Western diet, dieting and strenuous exercise are the commonly used methods to lose weight, they are not considered a permanent solution in addition to risk attenuation of basal metabolic rate (BMR). Pharmacotherapy offers benefits of weight loss by altering the satiety and lowering absorption of fat from the food; however, its side effects may outweigh the benefits of weight loss. Alternatively, dietary phytochemicals and natural health products offer great potential as an efficient weight loss strategy by modulating lipid metabolism and/or increasing BMR and thermogenesis. Specifically, polyphenols such as citrus flavonoids, green tea epigallocatechin gallate, resveratrol, capsaicin and curcumin, have been reported to increase lipolysis and induce fatty acid β-oxidation through modulation of hormone sensitive lipase, acetyl-coA carboxylase, carnitine acyl transferase and peroxisome proliferator-activated receptor gamma coactivator-1. In this review article, we discuss selected phytochemicals in relation to their integrated functionalities and specific mechanisms for weight loss.

 

 

7/ Novel curcumin - hyaluronic acid conjugate molecule improves curcumin's wound healing and antioxidant activity

Curcumin is a promising wound healing agent but its clinical application is limited due to being undiluted to water and lack of stability. However, curcumin conjugated to hyaluronic acid, has been found to be better than curcumin for fighting free radical damage and wound healing than plain curcumin.

6/ Curcumin is a stronger and broader anti-inflammatory than the steroid drug prednisolone...

...allowing it to combat numerous inflammatory diseases via multiple pathways (TNF-α and IL-6 expression by macrophages, IL-8 expression by colon epithelial cells, ROS production in polymorphonuclear leukocytes and platelet activation in whole blood). Specifically, curcumin is as good inhibitor as prednisolone for TNF-alpha and IL-6 and better than prednisolone for ROS, IL-8 and fibrinogen binding.

...by stimulating beta-3 adrenoreceptor gene expression and elevating the levels of plasma norepinephrine, albeit at quite high concentrations (50-100mg/kg of body weight). However, curcumin has been found in other studies to have a direct lipolytic and anti-adipogenic action, via additional mechanisms to thermogenesis. So the results of this experiment further add to the promise of curcumin as an anti-obesity and anti-cellulite natural chemical.

1/ Curcumin blocks the growth of new fat cells [in-vivo study]

This new study shows that curcumin represses the differentiation of adipocytes by inhibiting the protein miR-17-5p and by stimulating the Wnt signalling pathway, which is known to inhibit adipocyte growth. This is in addition to multiple other studies which show the anti-adipogenic and/or lipolytic potential of curcumin

curcumin protects fat cells from inflammation, helps fight cellulite

  • Dietary phytochemicals called polyphenols are known potent antioxidants that protect body tissues from free radical damage and consequent inflammation.
  • Inflammation and oxidative damage are key components of cellulite, as well as diabetes and several other so-called civilisation diseases, such as heart disease and arthritis.
  • Recent research has now looked into 28 polyphenols (such as hesperidin, resveratrol, epigallocatechin gallate and curcumin) and concluded that those polyphenols protect fat cells from both oxidative damage and inflammation, by reducing inflammatory hormones, such as IL-6.
  • This practically means that orally taken polyphenols (either as foods or as supplements) can be used in the fight against fat tissue inflammation for the prevention of diabetes and cellulite.
  • Polyphenols may also be used with local application in the fight against cellulite as active ingredients in an anti-cellulite cream. Naturally, the more of those polyphenols are present in the cream the better results are to be expected, due to a synergistic effect of using multiple ingredients.

  • Abstract: "Obesity has been associated with a marked risk of metabolic diseases and requires therapeutic strategies. Changes in redox status with increased oxidative stress in adipose tissue have been linked with obesity-related disorders. Thus, the biological effect of antioxidants such as polyphenols is of high interest. We aimed to measure antioxidant capacities of 28 polyphenols representative of main dietary phenolic acids, flavonoids, stilbenes and curcuminoids. Then, 14 molecules were selected for the evaluation of their effect on 3T3-L1 preadipocytes and human red blood cells exposed to oxidative stress. Analysis of reducing and free radical-scavenging capacities of compounds revealed antioxidant properties related to their structure, with higher activities for flavonoids such as quercetin and epicatechin. Their effects on preadipocytes' viability also depended on their structure, dose and time of exposure. Interestingly, most of the compounds exhibited a protective effect on preadipocytes exposed to oxidative stress, by reversing H₂O₂-induced anti-proliferative action and reactive oxygen species production. Polyphenols also exerted an anti-inflammatory effect on preadipocytes exposed to H₂O₂ by reducing IL-6 secretion. Importantly, such antioxidant and anti-inflammatory effects were observed in co-exposition (polyphenol and prooxidant during 24 h) or pretreatment (polyphenol during 24 h, then prooxidant for 24 h) conditions. Moreover, compounds protected erythrocytes from AAPH radical-induced lysis. Finally, these results led to demonstrate that antioxidant and anti-inflammatory properties of polyphenols may depend on structure, dose, time of exposure and cell conditioning with oxidative stress. Such findings should be considered for a better understanding of polyphenols' benefits in strategies aiming to prevent obesity-related diseases."
