While there’s no surefire way to remove a hickey in seconds, some people claim that applying toothpaste can help speed up the healing process. The cooling effect of toothpaste may reduce swelling and help stimulate blood circulation, which can make the mark fade faster. Simply apply a small amount of toothpaste to the hickey, gently massage it in, and leave it on for a few minutes before wiping it off with a damp cloth. Keep in mind that this method might not make the hickey disappear instantly, but it can help minimize its appearance temporarily.
