Lateral cheek (zygomatic arch) filler has recently been shown via ultrasound studies to have an incredibly high likelihood of migration/displacement into either the temple or lower cheek. There may be a lifting effect to the lower and mid face due to mechanical traction (nasolabial fold specifically) on the day of treatment, but in my experience, these results tend not to last. In addition, patients tend to the up with an unnaturally widened face - changing how they look rather than restoring facial balance. Approaching the nasolabial fold from a structural, anatomically based perspective helps ensure lasting results that target the actual cause of the problem - facial boney changes to the piriform fossa. The rheological properties of the hyaluronic acid filler that is chosen is also important - a high G prime (stiff and less resistant to deformation) is the ideal choice as it is the closest to mimicking the projection capability of bone.
