Microneedling for smooth skin

Suddenly I have developed a smile line indentation on only one side of my face a week ago and it doesnt seem to be going away. It feels like it appeared overnight and it extends all the way to my mouth. Nothing has changed for me recently like using new products or weight loss and I would like to remove the smile line indentation or make it less indented if that makes sense. I am under 20, is microneedling a possible fix to this issue to make it less noticeable or make it go away? Are there any other recommendations to help with this?
