I have red/brown skin on my face after microneedling, what can I do? Is this permanent?

Hi, Hyperpigmentation is caused by inflammation stimulating the melanocytes in your skin. This is not a normal outcome of microneedling but of a proceedure that created excess inflammation in your skin. Perhaps the settings were not appropriate for your skin or a roller was used or possibly the solution of liquid that was used during the proceedure was one that reacted with your skin. It is hard to know, but for sure under circumstances that microneedling is performed by someone with experience and training, this should not be the outcome.
I hope this resolves for you.
All the best
