Moist and healthy skin is the best foundation for a deep, dark, long-lasting tan. Using an indoor tanning lotion will help you get tan quicker, keep your tan longer, and have a more even tan. Tanning causes your skin to become dry and indoor tanning lotions can replenish your skin with moisture, antioxidants, and vitamins. Many indoor tanning lotions contain anti-aging properties or skin firming properties for healthy and young looking skin. It is also vital to use a good moisturizer specifically designed for indoor tanners. Not only do they moisturize your skin but help extend your tan as well.
