You picked bottle bronze over the sun—resulting in one streaky mess.
Squeeze fresh lemon juice onto a loofah and start scrubbing away dark splotches in a warm shower. If you have a few days before the area is revealed, smooth on a layer of body lotion containing alpha hydroxy acid (like AmLactin Moisturizing Body Lotion) both morning and night. "It increases the natural turnover of the skin cells, which will speed the fading process," Brandt says. If there's no time to spare, disguise streaks with a mix of half self-tanner and half moisturizer to lighter areas only once a day until they catch up with the rest of your bottle bronze.
