Sun Bum protects, moisturizes and tans our skin with their premium darkening lotion that they developed to accelerate the sun triggered tanning process in our skin. Their Natural Browning Lotion gets us that fast, deep tan, without having to spend long hours in the sun. To ensure protection, apply SPF 15 or higher sunscreen 10 minutes before applying Natural Browning Lotion. Also, heads up that the Natural Browning Lotion is brown in color and all the sweet ingredients that brown your skin can also stain your clothes so if you have a wild slather hand, make sure to toss your duds in the wash asap.
