Long-term use can easily cause the wound and the skin around the wound to turn white and soften, and even lead to secondary infection.

1. Wounds with larger wound surface and more blood loss;

2. Deep and narrow wounds, such as nail punctures;

3. There are contaminants on the wound surface or foreign matter in the wound;

4. Wounds caused by animal bites, such as dog bites, cat scratches, snake bites, poisonous insect stings, etc.;

5. Burns and scalds with ulceration and exudation;

6. Infected wounds or wounds with secretions or pus on the wound surface.

Do not wrap the Band-Aid too tightly when using it, otherwise it may easily obstruct the blood circulation of the injured part and cause ischemic necrosis. Before using a Band-Aid, check whether there is any dirt left in the wound. If so, the wound must be cleaned before using the Band-Aid.

If the wound is extremely painful, swollen, or has fever, it should be opened and checked immediately. If the wound is found to be infected with redness, swelling, or exudate, go to the hospital immediately.
