Kissing or sucking of the skin will result into this bruise-like mark. This happens when external tiny blood vessels disintegrate under the skin. But worry no more. There are a few hickey removal techniques that you can use in case you are caught in this awkward situation. A quick solution is found inside your fridge - the ice cubes. It will slow down the swelling process. With a little help of a cloth, press it into the affected area for about 20 minutes. Another convenient way is to use a toothbrush. Gently massage the hickey with the bristles, which will help the blood flow. And while you’re in the bathroom, applying a layer of toothpaste into the skin will help as well, for better flood circulation.
