Just like with hair dye, you need to test the shade of self-tanner to make sure it’s right for you. Apply it to a hidden part of your body (like your stomach) and wait a day or two. If you like it, then go for it. “It is always best to start with one shade darker than your natural skin tone,” Runne says. Try Victoria’s Secret Beach Sexy Adjustable Self Tanner with Shimmer, $14, which “allows you to control the amount of color you would like to achieve.”
