In rare cases, complications may develop, which include:
• Haematoma—caused by blood leaking into the surrounding area when the practitioner accidentally damages the wall of a blood vessel.
• Infection.
• Facial Asymmetry may be caused by several factors, including inadequate lifting on one side, inherent facial asymmetry, or the use of anaesthetic.
• Migration of threads may be due to weak barbs or if the thread overlays an area of excessive movement.
• Dimpling may occur if the skin is too thin, by excessive facial expressions or in a sunken cheek.
• Visible threads may be seen if they have been inserted superficially or the skin is too thin.
