Juvéderm® Hyaluronic Acid Dermal Fillers can only be administered by a qualified Medical Practitioner. Hyaluronic acid is a substance naturally found in the skin and side effects are very rare. Dermal Fillers can be used to treat many areas of the face to restore or add volume to lips, hollow areas such as tear trough, deep lines and scars on the face. Hyaluronic acid is extremely safe as it is eventually absorbed by the body, usually within six to nine months and require very little recovery time. Patients can return to day -to-day activities immediately.
