Hi domino47, all I can say is that taking Green Tea EGCG supplements has really worked for me for my horrible skin symptoms. And it's surely less expensive than everything else I'd tried, but I'd not tried frequency treatment. I saw improvement quickly with the green tea egcg capsules. And it's good for you anyway, you can find it anywhere, I've looked around and found this the best deal for me: http://www.pipingrock.com/green-tea/egcg-green-tea-600-mg-standardized-extract-3372 I hope you can find something for some relief soon.
