Why is my wound healing dark?

An excess of melanin moves to the injured area to speed up healing, and as a result, the surface skin becomes discolored, particularly around the edges of the original wound. Discoloration can occur in many different forms and levels of intensity, and colors can include shades of brown, gray, black, or red.

What does my scab look like when its healing?

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.

Are scabs just dried blood?

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.

When should you stop covering a wound?

Once the wound has formed a scab, there is no longer the need to cover it with a bandage as the scab now acts as a protective barrier. Keep the area clean, but be gentle so that you do not accidentally remove the scab.
