What are the pockets of fat at corners of mouth? Where did they come from? Do I need Perioral Mound Microliposuction? (Photo)

Thank you for your question and photograph.  Though nothing replaces an in-person examination, it appears that the pockets of fat in your photograph are actually the result of the aging process and the animation of your face muscles, predominately those used when smiling.  I would not recommend liposuction in this area, but rather dermal fillers to help camouflage the developing lines.  See that attached link below for more information.

this is not fat pockets, this is a combination of natural aging making the muscles more apperant and fat atrophy (drooping).  I suggest fillers to this area to camoflage what is occuring around your mouth.  Liposuction to this area is a bad idea and often leaves people with nerve issues and irregularity.  I am constantly fixing this with fat transfer, bellafill, and sculptra.  Please see an expert for a full facial sculpting consultation.  Best, Dr. Emer.
