Although saffron may bring Indian takeout to mind, experts like Klein say we'll see more of this multitasking ingredient in 2018, since the spice is rich in B vitamins and beneficial minerals, including folic acid. "Saffron spice is said to lighten, brighten, soothe, moisturize and decrease wrinkles, as well as combat acne," she says.

Saffron usually falls in the DIY beauty category but expect the ingredient to get a more commercial cosign this year, thanks to Saffron Secret, a new product line chosen as a trendsetter brand at COSMOPROF, geared around the ingredient.
