Scabs After Surgery

Scabs on Surgical Incisions

Question: My surgical incision has scabbed over, including my stitches. What do I do?

Answer:

A scab is a normal occurrence when your skin has been damaged. Whether you have skinned your knee or had major surgery, the formation of a scab is part of the healing process. Your skin has a remarkable ability to heal itself, using blood that moves to the site of injury to first stop any bleeding that may be present, then to seal the area so that healing may begin. A scab also works to protect the area, creating a harder “shell” at the site.

What Makes a Scab?

A scab is formed when parts of your blood work to stop the bleeding that happens at the site of an injury. Platelets, the part of the blood that clots, and fibrin, a fiber-like protein, work together to “seal” the injury, stop bleeding and form a scab. Without platelets and fibrin, we would bleed profusely from the smallest injuries.

Incisions, Skin Care and Scabs

It is completely normal for your incision to have a scab. This is a good indication that your incision is healing, as a scab is an early part of the process that fills in the incision with new skin and tissue, closing the wound. If pus is oozing from your incision, alert your surgeon. But you don't need to be alarmed about a scab.

It is important to not “pick” at your scab. It is equally important that you not scrub it during your shower. Removing the scab intentionally can increase scarring and slow healing. This is true even if the scab is forming around your stitches and making them appear discolored or dirty. Wash the area gently during your shower with the same amount of soap you would use on an area of your body that does not have a scab. Rinsing well is essential, as soap may irritate the wound.

When Will Your Scab Fall Off?

A scab may remain present for a few weeks, and it will gradually fall off with normal activity. Do not be alarmed if small pieces of the scab remain while other pieces fall off. Your incision may heal more quickly in some areas than others, especially if it is in an area where movement may place greater stress on small portions of the incision.

A shower or bath may soften a scab. This is not a problem as long as you don't “scrub” the scab off your incision. It is also normal for the skin underneath the scab to be more sensitive than the rest of your skin as well as pale or pink.
