Hello and thank you for your question. Microneedling can cause minor scabbing and flaking for a couple days post procedure. However, it is not normal to have multiple large/thick scabbing. As mentioned by others, that is a sign of an over aggressive treatment. The scabs can leave scarring if not cared for properly. When getting procedures done make sure your going to a qualified, experienced provider. Hope this helps, good luck to you.
Microneedling can cause tiny flakes of scabbing or dried blood during the initial healing period after the procedure. It is not normal to have larger or patches of scabbing which may indicate an overly aggressive treatment and increase risk of scarring. Hope this helps!Johnson C.
