Paris Hilton's Daily Must Haves, From a $13 Face Mask to a Flip Phone

Biodance Bio-Collagen Real Deep Mask ($19)

Paris Hilton's go-to mask is a bestseller, with nearly 8,000 reviews on Amazon. It starts out as an opaque mask that has a silicone-like feel, but you keep it on overnight, and in the morning it's transparent and ready to be peeled off. It's known to be extremely hydrating. "I love all things skin care. It's so important to have a routine, and face masks are a perfect little bit of me time," Hilton says.

She also loves the Omnilux Red Light Mask ($395) for a red- and blue-light therapy option. "I'll use it when I'm getting glam or winding down, and it always makes me feel like I've just left my Sliving Spa," she says, adding "I even had it custom bedazzled in pink crystals, of course."
