Can micro needling plump the skin up?

You know that indent above your Cupid's bow, but under the nose, it's the indent in the "moustache area" so to speak I feel like mine is too deep & looks weird. My esthetician said micro needling will plump that area? It's not too dramatic, just a nuissance to me. She said it's not "a big of a deal enough for a filler." But micro needling would do that the trick ?
