I've seen several high end beauty lines that charge a small fortune for face creams that contain this synthetic snake venom, revered as the new botox, sans injections. they claim it works just as well, albeit a bit slower since it requires multiple applications of the cream to see results. So my questions are: does this stuff really work? if so, how does one know how much is needed for the product to actually work? meaning is there a recognized minimum concentration needed for the claims to be true. i know that with some ingredients in creams, if they are bellow a certain % of the product, you are wasting your money since there's not enough in there to do what the product claims it does....
