First we made our best-selling Firm & Tone Body Butter into a spray tan solution! Now we’ve made it into a self-tan mousse too! We’ve harnessed the power of caffeine and guarana, known for their firming and toning benefits into this self tan. At A Glance: Whether you’re hitting the gym, going for a run, or simply enduring a busy day, this tan is extra sweat resistant. Mixed Base with neutral chocolate-brown base, making it the perfect match for almost all skin undertones – warm, neutral, or cool.
