d'Alba Italian White Truffle First Spray Serum ($20)

"I love spray-on skin care because it's so easy to apply," Giles says. "This serum keeps my skin hydrated and glowy in the morning and after a long day of filming. I use it every day."

Perfect for dry skin, this spray has a citrus floral scent and includes premium white truffles that were extracted from Piedmont, Italy and infused with vitamin E. It's rich in antioxidants, certified vegan, and hypoallergenic.
