Fire boils on the face are also known as boils, which are mainly caused by pathogenic microbial infections, high temperature, excessive sweating, scratching, poor hygienic habits, systemic chronic diseases, organ transplants, long-term application of glucocorticoids and other triggering factors. 1. Pathogenic microbial infections: this disease is mostly coagulase-positive Staphylococcus aureus infection, occasionally for Staphylococcus epidermidis, Streptococcus, Pseudomonas spp., Escherichia coli and other individual or mixed infections, but also by fungal folliculitis secondary to bacterial infections. 2. High temperature, excessive sweating, scratching, poor hygiene habits: in a hot and humid environment, sweaty skin, sebaceous secretion discharge is not smooth, skin scratching, abrasions and other injuries, as well as poor hygiene habits, localized skin impurity, etc., is prone to induce the emergence of boils. 3. Chronic systemic diseases: such as diabetes, malnutrition, anemia, chronic nephritis, neutrophil dysfunction, etc., the body’s immunity decreases, which can easily trigger boils. 4. Organ transplantation: Organ transplantation patients with reduced immunity are prone to infection with pathogenic microorganisms, which may induce boils. 5. Long-term application of glucocorticoids, such as prednisone, dexamethasone, etc. Long-term use of large quantities of hormone drugs will easily lead to a decline in the body’s resistance, thus inducing boils. It is recommended that patients should consult the doctor in regular hospitals after diagnosis, and follow the doctor’s instructions for reasonable treatment to avoid delaying the condition.
