Article in English: Placing an ice pack on the hickey as soon as possible can help to constrict blood vessels and reduce swelling. This may make the mark less noticeable.  Wrap the ice pack in a clean cloth to minimize your risk of frostbite. You can also place a cool spoon on the hickey, but be sure to not rub it into your skin.  You can also use a bag of frozen vegetables, such as peas, or freeze a Styrofoam cup of water if you don't have an ice pack. Leave the ice on the hickey for up to 20 minutes at time. Make sure to wait for an hour or two after applying ice to apply it again. Apply the ice several times a day for a day or two. If your hickey is swollen after two days, you may want to apply a warm compress to the area. Heat therapy helps to open up blood vessels and increases blood flow, which can promote healing.  Use a heating pad or cloth soaked in warm water.  Apply heat for up to 20 minutes at a time several times a day. Make sure to give your skin a chance to return to its normal temperature after each heat application or you may burn your skin. Aloe vera is a natural moisturizer. It may help to promote the healing of a hickey. Try smoothing a thick layer of aloe vera onto your hickey. Leave it on for about 10 minutes. Then, wipe away the aloe vera with a tissue. Do this twice per day until your hickey has healed. Though there is no evidence that this actually works, some say that holding the inside of a banana peel on your hickey can help to cool the area, which may reduce the size of a hickey. Peel a banana and place the inside part of the peel on your hickey. Hold it there for up to 30 minutes, and then wipe away any excess banana with a tissue or damp cloth.
