Should you pick a scab? No, and here is why
A scab is a temporary emergency roof. Removing it early exposes the repair underneath.
A scab forms when a wound is left open to the air and the surface dries. It is the body improvising a cover.
Why picking sets you back
Underneath a scab, new skin is creeping across the wound. Pulling the scab off tears that layer away, restarts bleeding, and adds to the final scar.
Better than a scab
A covered wound does not need to form a thick scab at all. Kept at the right moisture level under a dressing, new skin migrates across faster than it can under a dry crust. That is the whole rationale for modern dressings.
If a scab has formed
Leave it. Keep it covered so it stays supple and does not crack, particularly over a joint. It will separate on its own when the skin beneath is ready.
When to be concerned
A scab that is growing, weeping from underneath, or surrounded by spreading redness is not doing its job. Get it seen.
See a pharmacist, GP or urgent care if a wound will not stop bleeding after ten minutes of firm pressure, is deep or gaping, was caused by something dirty or rusty, contains anything you cannot flush out, or shows spreading redness, heat, swelling, pus or a fever. Get help urgently for animal or human bites, wounds over a joint, and any wound in someone with diabetes or poor circulation.
