Eva Chen's Must Haves: From H&M Tees to a $12 Sleeping Mask

Depending on the time of year, one of Chen's tried-and-true beauty products is the Clé de Peau Radiant Stick Foundation ($75). Doubling as an SPF, this foundation creates a lightweight, natural makeup look that lasts all-day long. "Depending on your skin tone, it can be challenging to find the perfect foundation or concealer. But this shade lasts forever," she explains.
