many of the skin creams that i use are rotting in my vanity box,i dont even use them ,as they have failed to deliver any kind of result . Some of them have but not to a large extent. They have faired average or poorly according to me. Since i am having exremly oily skin my mother in law told me about creams with egcgb that improve skin texture? are these egcg skin cream contain any kind of oils ?what else other than egcg is included in these egcg skin creams? what are the other skin related benefits it caters to? and how well does it blend with oily skin?
