I have a cold sore it scabbed and fell off but now looks like another scab is forming i'm wondering how many scabs have to before it's completely gone?

1 doctor agrees

In brief: One or more

No magic number, depends on skin conditions, moisture, picking at it, etc.
More important is how well-healed / progressed the lesion is under scab when/if it comes off.
