"I think mousses are the easiest to rub in, but sprays are great for hard-to-reach areas," Stankiewicz says. The rule of thumb? Choose a self-tanner for your skin tone, not your desired result. Go with a light to medium formula if you have fair skin and a dark formula for olive tones. If you opt for a gradual formula, remember that it can take two to four applications to reach the right shade. St. Tropez Self Tan Dark Bronzing Mousse is one of our favorites for body, while we love Clarins Liquid Bronze Self Tanning For Face and Décolleté for our face.
