It would be slightly worse than taking it off in space. The atmosphere on the surface of Mars is nearly a vacuum, so the astronaut would do well to notice the boiling saliva and tears and reseal the helmet immediately. Failing that, he or she would pass out in a few seconds, which is perhaps just as well. In space, you can only cool off by evaporation or by radiating infrared into space. On Mars, the tenuous air is just barely thick enough to conduct heat, and it’s generally colder than northern Siberia in the January. So…yeah. Don’t do that.
This can take about 3-5 days total to heal, but keep in mind swelling can vary from person to person. One person can stop after one day, but another person can take about 2 days.
