Remember that you can only lighten the hickey and not make it disappear completely. Here are a few tips to lighten them:

1. Apply a cold compress on the hickey immediately after you notice it. Use something round and massage the area in a circular motion while applying light pressure. Don't press too hard as the mark will only get worse. Keep a metal spoon in the freezer and massage your hickey with it. However, don't apply ice.

2. If your hickey shows no signs of going even after 48 hours, apply a warm but wet compress. This will reduce any pain and swelling. When the blood stops spreading around the hickey, apply heat. This will dilate the blood vessels which will speed up the sweeping away of blood cells.

3. Massage your hickey with a little vitamin E. This will help in reducing the appearance of a hickey to a great extent.

4. Choose a concealer that is lighter than your skin tone but one that will be discreet and not grab attention and dab it on the hickey. But make sure you dab it only on the hickey and not the surrounding area or it will make your hickey stand out even more.

5. When everything else fails, a turtleneck shirt is your last hope.
