Appreciate scabs can fall off if picked but if not picked how do they naturally “fall off and go away”?
Such as flat scab? Do they get pushed off due to new skin underneath pushing it?
In: Biology
Basically the scab doesn’t get “pushed off” but it is no longer needed and the underlying skin has healed enough to be exposed (tissue regeneration). The drying and weakening of the scab causes it to naturally fall off due to everyday minimal friction.
