The responsibility for risk assessment, having a complications protocol in place and an Emergency Complications Kit accessible, lies with the sponsor of the session and the practitioner performing the treatment. However, in the extremely rare event of a complication occurring, the Aesthetics Complications Expert (ACE) Group World will be on-hand if a practitioner is not able to deal with a problem, needs an extra pair of hands or a second opinion.   They will also have an ACE Group Emergency kit available on their stand, which will be well stocked with hyaluronidase and adrenaline so if a complication occurs, necessary drugs and consumables will be readily available.
