How does a scab form?

Scabs patch up holes in the skin. Certain cells in our bloodstream recognize when our skin has been broken. These cells, called platelets, start patching the break in the skin and call in other blood components to help complete the process. They do an amazing job. Don’t make your platelets work overtime by picking your scabs!
