We use it on some skin-tears in the nursing home I work at. Also use it for topical disinfection of the area prior to catheter insertion.
A new scab will form because you removed the scab before it could fully heal. The new scab will not be as thick as the old one, and will be more prone to breaking and getting infected. When it comes to scabs, if it does not flake off easily, it is not time to remove it. Debriding a wound is something a doctor does, not the patient. Don't debride your own wounds unless you know exactly what you are doing. Be extra mindful of feelings of "warmth", localized swelling, and redness in the area just under and around where you have removed the scab. If you experience any of those, see your GP right away. In the mean time, keeping the site protected but dry, and treatment with a dry antibiotic (again, betadine unless you are allergic to iodine) will be your best care plan at this point.
(The scab is more than just a protective covering when it comes to deep tissue regeneration you know. The scab will be full of fibroblasts and deposited fibronectin, which is used as the scaffold for new tissue migration in the healing process. By dislodging the scab, you have greatly reduced the site's ability to properly fill in tissue. If it were my wound, I would attempt to make it bleed, so that new deposition of these factors will occur. However, I do not recommend doing that without GP approval for other people. The GP may discourage that action, as it opens the wound and risks infection in a big way until it closes again. Really, you should not have removed the scab,)
