It can take about 4 days to a week for the purple/red mark to turn to a yellow and approx. 2 weeks to go away completely. The reason for this is when someone is sucking the skin on your neck, it draws the blood just under the skin (like a bruise.)
Fortuanetly for us, hickey's are not permanent. They go away after a couple of weeks. It's just like a scrape or a cut, they go away as well.
Hickey's are bruises, plain and simple. They go away with time...If you're desperate, go try bruise remedies. Otherwise, use makeup.
