With a celebrity following including Kate Moss, Sienna Miller, and Poppy Delevingne it's no wonder the revolutionary new In-Shower Gradual Tan ($31) by St. Tropez has sold out world-wide, with thousands signing up for notification of it's return. Why the hype? Unlike typical self-tanners, the St. Tropez In-Shower Gradual Tan works within three minutes, and is incorporated into your daily shower routine to deliver a sun-kissed, gradual glow that is always streak-free. Plus the inclusion of sweet almond oil, which is clinically proven to hydrate the skin for 24 hours, means there's no need to moisturize post-shower, making it a must-have for the girl on the go.
