I have not seen Voluma migrate in the patients that I have treated and I have not heard of migration being an issue for patients treated by other doctors. The Voluma should stay in the area that was injected, so I would say that it would not migrate from the cheek to the jawline or smile lines.
Thank you for your question. It is highly unlikely for cheek filler to migrate to jawline and smile lines. Always consult with a board certified medical professional for your treatment.
