I asked customer service this question through the website after reading the other answers here. (I also got the hydrating mineral veil and have only the normal brushes--and didn't want to spend money on more brushes right now.) Here's the answer I got from a customer service person: "You can definitely use your normal brushes with the Hydrating Mineral Veil; the hydrating properties arise from the water bound into the formula and not the brush." There seems to be no hesitation or attempt to push the "Hydrate and Brighten" brush, so I don't think the hydrating mineral veil needs it for any reason.
