Green tea and acne connection? recently i have been drinking large amounts of it coupled with high doses of biotin. my acne scars are nearly gone.

No connection: Glad you are better. But neither the tea nor the biotin had anything to do with it.

Green tea: I think that it is mainly the antioxidants in the green tea that reduces inflammation and may decrease the androgenic hormonal effects to some extent that are helping. Biotin often makes acne worse. I am not sure about biotin and scar healing. Be thankful that your acne scars have essentially resolved. Biotin has nutritional benefits otherwise.

Difficult to know...: There are many anecdotes that topical green tea bags cures people's acne, but there is little in the way of any research, let alone double blind, placebo-controlled trials, which are the gold standard of assessing a potential treatment. Nevertheless many people think that green tea cures acne, possibly due to antioxidants known to be in green tea. It would be useful to investigate this further.
