I've been using Revitalash since November of last year. This stuff works! It took about 30 days for my lashes to grow longer. I use just a tiny amount (I wipe the excess off on the lip of the tube) and a little goes a long way. For those who live outside of the US it's available at Skinstore and they'll send it USPS. http://www.skinstore.com/store/product.asp?catID=0&prodID=8016
