Introduction

The shelf life of burn ointment is generally 2 to 5 years, and the specific expiration date should refer to the label on the product packaging. Unopened products can maintain their efficacy under specified storage conditions, but the shelf life significantly shortens once opened. If skin redness, swelling, worsening itching, or poor healing of the burn wound occurs after using expired burn ointment, medical attention is recommended promptly.

　　The shelf life of burn ointment is generally 2 to 5 years, depending on the expiration date indicated on the product packaging. Unopened products can maintain their efficacy if stored under recommended conditions, but the shelf life shortens once opened. If skin redness, swelling, or increased itching occurs after using expired burn ointment, or if the burn wound fails to heal properly, medical attention should be sought promptly.

　　Unopened burn ointment remains stable due to its sealed packaging and formulation consistency. The shelf life is typically determined by the manufacturer based on the formula and production process, usually lasting 2–3 years, while certain products containing special active ingredients may last up to 5 years. The packaging clearly indicates the production date and expiration date.

　　Once opened, burn ointment is exposed to air and potential microbial contamination, which may cause oxidation and degradation of its components. Its shelf life is generally reduced to 3–6 months. Improper storage—such as exposure to high temperatures, humidity, or frequent opening leading to contamination—can further shorten its usable period. Therefore, changes in texture or appearance should be monitored to determine whether the ointment is still safe to use.

　　Burn ointment should be stored in a cool, dry place, away from direct sunlight and high temperatures. After each use, the cap should be tightly closed. Before use, check the ointment’s consistency; if any unusual odor, cloudiness, separation, or discoloration is observed, the product should be discarded immediately and not used under any circumstances.

How long does it take to recover from an aluminum molten metal burn?

The recovery time for aluminum melt scalds depends on the severity of the injury. In mild cases, where only redness and slight swelling and pain occur on the skin surface, with no blisters or only small blisters, the skin can gradually heal within 1–2 weeks after proper treatment such as rinsing with cool water, applying burn ointment, and protecting the wound. Healing typically does not leave obvious scars. During recovery, it is important to keep the wound clean and dry to prevent infection.

What should I do for a burn to prevent blistering?

First aid measures to help prevent blistering after a burn generally include immediately rinsing the area with cool water, soaking the injury in cold water, avoiding rubbing or pressing the affected area, applying specialized burn ointment, and covering the area with sterile gauze for protection. After a burn, promptly place the injured area under running cool water for 15–20 minutes. Cold water quickly removes heat, lowers skin temperature, and reduces damage to deeper tissues caused by thermal energy.
