April Gargiulo’s foray into skin care started simply enough. She had been researching her favorite products on ewg.org and realized many of them were packed with toxic ingredients and fillers. So the vintner (her family owns a winery in Napa Valley) started a side project: creating a supremely effective face oil with no harmful ingredients. It took two years to develop what would become an iconic product, a luscious face oil packed with twenty-two active botanicals that make a noticeable difference in your skin. (GP, makeup artists all over the world, and our beauty director, Jean Godfrey-June, are all huge fans.) In 2019, Gargiulo created a second product, a powerful treatment essence, which treats skin to water-soluble nutrients—the yin to the serum’s yang. Used together, the pair works to transform any skin type.
