In addition to the catchy hook, Rihanna's fresh complexion was another element of her "Stay" music video that stuck in our minds. (We can't stop watching it!) Her secret? Hydration. The star's makeup artist Mylah Morales used a combination of Koh Den Do's Cleansing Spa Water and the Oriental Plants Milky Lotion to impart a dewy finish. "I prepped her skin using the Cleansing Water to replenish and rejuvenate," Morales said. "To lock in moisture, we used the Oriental Plants Milky Lotion during the video shoot." Thanks to the Japanese spring water and rosemary, ginger root, and sage extracts mixed into the formula, the Cleansing Spa Water doubles as a makeup remover and a toner, while the lotion adds a boost of hydration and strengthens your skin's outermost layers. Pick up both for $39 and $84 at kohgendocosmetics.com.
