Has anyone tried this stuff- vita liberata pHenomenal 2-3 week tan? Bought it really because its peeing with rain here, freezing and I still have my big winter jacket on when I set foot outside so thought I would cheer myself up by "glowing"! However now a little nervous I may spend the next 2-3 weeks looking tango'd if I gt it wrong. Has anyone had success or otherwise with this product?
