The patient’s history is important, with in-depth questioning to find out what happened from the moment they got up, the temperature of the water they bathed in, their diet, and what they do for a living. “Even the region of Guatemala where they live is an important detail,” says Champet Lima.

“Some patients tell me that they only eat coffee and bread for breakfast, they eat junk food for lunch, they don’t drink water and they eat dinner late because they are tired, but this lifestyle doesn’t help their recovery, and poorly managed emotional stress also makes it slower,” adds the dermatologist.
