Getting rid of hickies is impossible, but treating a hickie is possible. Immediate attention is required if you want that hickey to go away fast. Apply ice in a wrapped paper towel. Hickeys cause swelling. The ice will reduce that swelling. Massage the area where the hickey is. A hickey is a bruise, so massaging the area will help break up the bruise. Apply heat 24 to 48 hours afterwards will help get rid of it also. Use a warm washcloth for several minutes, several times a day. If the hickey is painful, take Advil or Tylenol. Girls can use a green tinted concealer to help cover the hickey. Guys try a bandage, but come up with a good story as well.
There is no immediate cure for a hickey, but you can take steps to make it less noticeable. As soon as possible press ice onto the area. This will help keep the redness down. Rubbing can also help. Use a spoon, brush, or comb and be very gentle. You can also try putting Visine or Vitamin K directly on the skin to reduce redness further. If you've tried everything and you're still embarrassed to go out, use an old standby. Heavy concealer, turtlenecks, and scarves are all classics for a reason.
