EGCG / green tea and your skin

Skin/wound repair, fibrosis, anti-ageing and cellulite

The green tea extract EGCG (epigallocatechin gallate) is the most important active molecule in green tea and responsible for most of its beneficial effects. EGCG is well researched for it's antioxidant, lipolytic, skin repair, anti-fibrotic and overall anti-ageing action.

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

Below you can find a comprehensive review of all the research papers on EGCG / green tea extract and it's effect on ageing, skin health and cellulite.


EGCG: The science



EGCG is a great complement to the anti-inflammatory action of the steroid drug prednisolone...

...combating inflammation via multiple, complementary to glucocorticoids, pathways. Specifically, EGCG significantly inhibits ROS and IL-8 (prednisolone doesn't) and is equally effective in fibrinogen binding (conversely, EGCG does not inhibit TNF-alpha and IL-6 that respond to prednisolone).

EGCG boosts brown fat thermogenesis and mitochondrial biogenesis...

...evidenced by increased temperature, fat loss, mitochondrial DNA (mtDNA) and AMPK

EGCG acts as a caloric restriction mimetic and boosts lipolysis... upregulating adipocyte autophagic lipolysis, reducing adipocyte triglycerides by 25%, intracellular ATP levels by 49% and inducing AMPK phosphorylation, indicating an energy-depleted state. However, EGCG does not casue adiciyte browing.

epigallocatechin gallate in food 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."
