If you decide on a sun-kissed look of a spray tan, now's the time to go back for round two. On the day of your treatment, exfoliate skin, and avoid using any perfumes, deodorants, or moisturizers that can create a barrier on the skin and cause your tan to look blotchy. Eileen Bischoff, a spray-tanning expert at Eve Salon in New York City, says, "Also be sure to wipe petroleum jelly over your nail beds, the palms of your hands, soles of your feet, elbows, and in between your toes and fingers. It will prevent those areas from overdeveloping and turning orange." After tanning, dust talcum powder into your knee, elbow, and neck creases to absorb excess oils and prevent the tint from rubbing away. On the big day, repeat this step before slipping into your wedding gown.
