ok, couple of things. 1. pretty good copy, look for small grammar mistakes you made there sometimes. 2. in a product like this that relates to an intimate place like your face I would go deeper on the safe emotion. something like "researches have shown that...." "if it doesn't work get full refund no question ask" try to minemize their skeptical voice. 3. hope it helps, 6\10 keep up the work man.
