Dr. Gan Liqiang
Whether an insect bite results in blistering depends on the individual’s constitution. Some people with robust constitutions exhibit no obvious reaction, whereas others—particularly those with more sensitive skin—may develop prominent blisters or even large bullae. Many insects, such as fleas and ants, commonly cause blistering upon biting. Moreover, certain insects inject toxins that trigger skin inflammation, necessitating anti-inflammatory treatment.
