According to healthline.com, “Research on pig skin by the Swiss Federal Laboratories for Materials Science and Technology showed that steam can penetrate the outer layer of the skin and cause severe burns on lower layers. While the outer layer does not appear to be severely damaged, the lower levels can be.” The burn is caused by the heat released when the high-temperature water steam changes to low-temperature water liquid in a short time.
