Will messing up post care after microneedling case permanent scarring or discoloring? (photos)

Hello,
With any procedure, it's all about the post care.  Make sure any provider gives you detailed follow up instructions and also has easy access to the instructions as like you mentioned, it can be daunting to remember it all.  You definitely want to think gentle until full healing as occurred, including sunscreen, no acids, no scrubs, and nothing harsh to the face.
We always go through a detailed consult and send all our clients follow up emails with post care instructions.
Thank you,
