An at-home spray tan may sound intimidating, but DIY systems like Luminess Tan ($159; luminessair.com
) are surprisingly easy to mastereven if you're a beginner. Create a flawless finish by applying your spray tan in layers. "Begin spraying your base coat first onto your front, back, and sides, then spray on the second coat, concentrating heavier application on your natural curves and contours," said St. Tropez tanning expert Sophie Evans, who works with Victoria Beckham and Kate Beckinsale. "Afterward, give nails and palms a thorough cleaning to avoid staining, and lightly buff your skin with an applicator mitt to really blend the color." The color takes time to set and dry so plan ahead.
