Nicky Hilton Shares Her Must-Have Products, From Lip Products to a Cozy Robe

Hilton also uses the U Beauty Plasma Lip Compound ($68) when she wants a tinted lip treatment. "I love it because it hydrates and plumps your lips, and it just makes your lips soft and smooth," she says. It's formulated with peptides, ceramides, a gentle blend of AHAs and BHAs, shea butter, and beeswax. It comes in 13 shades, and Hilton loves sporting the pale petal pink shade.
