Can microneedling cause scabbing?

Thank you for your question!  When microneedling, you create microchannels in the skin.  You may note pin point (petechial) bleeding with some flaking post-procedure.  However, if you have large scabs, this could mean the procedure was not performed correctly or too aggressively. 

microneedling, lasers, peels call can cause scabbing and need proper skin care.
For Antiaging, I would suggest a combination approach of :
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel, Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
Best, Dr. Emer.

Hello there,
     It is not typical to experience scabbing from this treatment. In my experience, most patients will experience some rough, dry, irritated, sensitive areas. There also may be some flaking or peeling that occurs, but never actual scabbing. I would be concerned if this occurred. I would definitely discuss this with your provider.
