“The key: Gorgeous makeup starts with gorgeous skin. I really believe in keeping things fresh and not caked on with foundation,” Stern says. To give Witherspoon her dewy complexion, Stern first prepped the actress's skin by spritzing on an invigorating facial spray and then massaged in RéVive Intensité Moisture Serum Extrême ($365; to lock in the moisture. She finished things off by applying RéVive Intensité Crème Lustre Day ($385; to increase elasticity and boost the skin’s youthful glow. Since Witherspoon was going to be wearing a vivid hue on her lips, Stern treated them with RéVive Intensité Lip Balm ($60; to ensure an even application of the lip color to last through the night.
