Should you pop blisters caused by burns?

Generally, whether a burn blister should be punctured depends on the size and location of the blister. Small, intact blisters in areas less prone to friction do not need to be broken. However, large blisters or those located in areas susceptible to damage require proper medical drainage—never break them arbitrarily. Specific details are as follows:

If the blister is less than 1 cm in diameter, has intact skin, and is located in low-friction areas such as the inner forearm or torso, the blister roof acts as a natural barrier against bacteria and protects the wound. In this case, rinse the area under cool running water for 15 minutes, then apply burn ointment. Keep the area clean and dry—the blister will gradually be absorbed by the body without needing to be broken, thereby reducing the risk of infection.

If the blister exceeds 1 cm in diameter or is located in high-friction areas such as the palms, joints, or near clothing edges, it is more likely to rupture due to movement, increasing infection risk. First disinfect the blister and surrounding skin with iodophor. Then, use a sterile needle to make a small hole at the lowest point of the blister to drain the fluid, while preserving the blister roof to cover and protect the wound. Finally, apply an antimicrobial ointment and gently bandage the area.

In daily care, avoid pressing or scratching the blister. When bandaging, ensure the dressing is neither too tight nor too loose to prevent friction. Change the dressing daily after drainage and monitor the wound for signs of redness, swelling, or discharge. Nutritionally, consume more protein-rich foods to support tissue healing. Always take protective measures when handling hot objects to reduce the risk of burns.
