Use a self-tanner to achieve a sun-kissed glow without having to expose your skin to the damaging effects of the sun. Self tanning can be tricky, so follow these tricks to ensure a streak-free tan each time. Exfoliate - a tanner will stick to rough, dry skin, leaving dark spots. Start from the bottom and work up. Starting at the ankles ensures an even application along with allowing ample time for tanning products to dry. Don't be impatient, gorgeous, glowing skin is worth the wait.
