If there's one person who consistently delivers that impossibly sleek, expensive-looking beauty vibe, it's Amal Clooney.

Turns out, her secret isn't some under-the-radar salon treatment. Clooney relies on the Color Wow Dream Coat Supernatural Spray to achieve that signature glass-like finish, according to InStyle.
