How to Get Rid of a Hickey – eHow.com

1. Apply a cold compress immediately (although that may interrupt a moment of passion). Keep the compress on 20 minutes, off 20 minutes. The cold will constrict blood vessels and help keep the bruise from spreading. (Image 1)

2. If the hickey lasts for more than 48 hours, apply wet, warm compresses to decrease any pain or swelling. Once the blood has stopped spreading around the bruise, apply heat, which dilates blood vessels and thus speeds up the sweeping away of blood cells. In most cases, moist heat is more effective than dry heat, because the moisture helps wick the heat beneath the skin. (Image 2)

3. Apply concealer in a shade that’s lighter than your natural skin color and discreet enough to fend off unwanted attention. (Image 3)

4. Remember that if all else fails, nothing beats a turtleneck sweater – or a scarf in summer.
