A laceration is technically a defect in the skin resulting from tearing, stretching, or shearing forces. In practice however, the term is often used for any cut that goes all the way through the skin. A small cut can be cared for at home. A large cut needs prompt medical attention.

If the cut is minor, a liquid bandage (liquid adhesive) can be used on the cut to close the wound and help stop bleeding.

A liquid bandage is quick to apply. It causes only slight burning when applied. Liquid bandages seal the cut after only 1 application. There is less chance for infection since the wound is sealed shut.

These products are waterproof, so you can shower or bathe without worry.

The seal lasts for 5 to 10 days. It will fall off naturally after it has done its job. In some cases after the seal falls off, you can reapply more liquid bandage, but only after seeking medical advice from your health care provider. But most minor cuts will be healed at this point.

Using these products may also reduce the size of scars that form at the injury site. Liquid skin adhesives can be found at your local pharmacy.

With clean hands or a clean towel, wash the cut and surrounding area thoroughly with cold water and soap. Dry with a clean towel or gauze pad. Make sure the site is completely dry.

The liquid bandage should not be placed inside the wound; it should be placed on top of the skin, where the cut comes together.

• Create a seal by gently bringing the cut together with your fingers.
• Apply the liquid bandage over the top of the cut. Spread it from one end of the cut to the other, covering the cut completely.
• Hold the cut together for about a minute to give the adhesive enough time to dry.

Do not use liquid bandage around the eyes, in the ear or nose, or internally in the mouth. If the liquid bandage is accidentally applied to any of these areas, call your provider, 911 or the local emergency number.

It is OK to bathe after the liquid adhesive has dried. Do not scrub the site. Doing so may loosen the seal or even remove the adhesive completely. It is also OK to wash the site with soap and water daily to keep the area clean and prevent infection. Pat the site dry after washing.

Do not use any other ointments on the site of the cut. This will weaken the bond and slow the healing process.

Do not scratch the site. This will remove the liquid bandage.

Keep the following in mind:

• Prevent the wound from reopening by keeping activity to a minimum.
• Make sure your hands are clean when you care for the wound.
• Take proper care of your wound to help reduce scarring.
• Contact your provider if you have questions or concerns about how to care for your wound at home.
• You can take pain medicine, such as acetaminophen, as directed for pain at the wound site.
• Follow-up with your provider to make sure the wound is healing properly.

Contact your provider right away if:

• There is any redness, pain, or yellow pus around the injury. This could mean there is an infection.
• There is bleeding at the injury site that does not stop after 10 minutes of direct pressure.
• You have new numbness or tingling around the wound area or beyond it.
• You have a fever of 100°F (37.7°C) or higher.
• There is pain at the site that does not go away even after taking pain medicine.
• The wound has split open.
