EGCG / green tea and your skin
Skin/wound repair, antioxidant activity, fibrosis, anti-ageing, 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.
Green tea / EGCG cream
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].
How much EGCG IS THEre in dried green tea leaves / IN A TYPICAL CUP OF green TEA?
Dried green tea leaves contain anything between .2%-20% EGCG per weight, with an average percentage of 7%. This means that a double strength 2g green tea portion can provide you with about 140mg of EGCG, if allowed to brew for five minutes. In this respect, green tea is unique among most herbs in that it contains a really high amount of beneficial actives, compared for example to 0.5% of polyphenols contained in cocoa powder or 1% triterpenes contained in dried centella/gotu kola leaves.

Does Matcha green tea contain more EGCG than normal green tea?
It seems that the EGCG contained in a cup of normal green tea and in a cup of matcha tea is roughly the same, according to the study below (0.42mg/g of normal tea vs 0.28mg/g of matcha tea - please note that these numbers are for cups of 75ml finished tea, not per 1g of green tea leaves). With 100% methanolic extraction matcha tea seems to contain a lot more EGCG, but then again our stomach does not use 100% methanol extraction, so the report on the methanolic extraction of EGCG from green tea in this study is quite pointless.

Sencha green tea vs matcha green tea
It seems that a less known variety of green tea powder, sencha green tea powder, contains more EGCG and catechins in general, than matcha green tea.
