The key players in scabs are cells in the blood called platelets. When your skin is cut or scraped, you bleed. As blood is exposed to air, platelets rush to the scene and begin sticking together. They work with proteins called fibrin and other substances to form a scab, which is basically a blood clot on the skin.
Maceration occurs when skin has been exposed to moisture for too long. A telltale sign of maceration is skin that looks soggy, feels soft, or appears whiter than usual. There may be a white ring around the wound in wounds that are too moist or have exposure to too much drainage.
Here’s the kicker: It may feel like the wrong thing to do, but research shows it can be OK to pick a scab. Picking can actually help the healing process because a scab that’s on for too long increases scarring.
A Covered Wound: Using a sterile bandage or cover after applying a NEOSPORIN® Original Ointment, helps prevents exposure to dirt and germs. Has less chance of scarring. A moist, scab-free wound is more likely to heal without leaving a visible scar.
Chronic wounds, by definition, are sores that don’t heal within about three months. They can start small, as a pimple or a scratch. They might scab over again and again, but they don’t get better.

The clots turn into scabs, and, underneath, fibroblast cells produce collagen, a protein that connects tissues together. In a weeks-long process, the collagen creates new capillaries and the skin on the edges of the wound gets thicker and starts stretching under the scab.
While it heals the scrape may stay moist and pink and ooze fluid or small amounts of blood. Over time, the area will turn pink and shiny as the new skin forms.

When your skin is cut, scraped, or punctured, you usually start to bleed. Within minutes or even seconds, blood cells start to clump together and clot, protecting the wound and preventing further blood loss. These clots, which turn into scabs as they dry, are created by a type of blood cell called a platelet.
