1. Invest in a pair of earring backs that will not infect your ears. Most jewelry stores will sell you gold or platinum backs for $10-$20 per back.
2. Paint any part of the earring that touches your skin with clear nail polish. I usually paint on three coats. Let the earrings dry between coats.
Note: Try not to wear the earrings in water. The clear nail polish acts like it does on your nails - it will chip! If your ears start turning that dreaded shade of pink, you know it's time to repaint. If you want to be extra cautious repaint after every 2-3 wears!
