Hyaluronic Acid Contraindications

Injectable hyaluronic acid filler is generally contraindicated when there is an active infection or inflammation at the planned injection site, or a known hypersensitivity to the intended product or one of its components. This can include lidocaine when it is present in the formulation. Treatment is also commonly postponed during pregnancy and breastfeeding because safety information is limited. Other health conditions, medicines and previous procedures may require additional caution rather than automatically ruling out treatment.

Treatment is usually deferred if the skin in the intended area is irritated, inflamed or infected. Active acne lesions, cold sores and facial or dental infections can be relevant, depending on where treatment is planned. Feeling unwell or recovering from another procedure may also affect timing. Delaying treatment allows the area to settle and reduces avoidable uncertainty before an injection.

Blood-thinning medicines, medicines that affect clotting and some supplements may increase bruising or bleeding, but they are not always an absolute contraindication. They should be discussed before treatment, and prescribed medication should never be stopped without guidance from the clinician who prescribed it. Autoimmune conditions, immune suppression, bleeding disorders, poorly controlled medical conditions and a history of severe allergic reactions also require careful consideration.

A practitioner should know about all previous facial injections, including where they were placed, when they were performed and whether the material was temporary, permanent or unknown. Previous complications, surgery, implants, threads, scarring or recent dental work may influence the treatment plan. Photographs or records from earlier procedures can be helpful when the details are available.

A contraindication is a reason to avoid or postpone treatment. A risk is a possible unwanted effect even when treatment is considered appropriate. Hyaluronic acid filler can cause temporary swelling, tenderness and bruising, as well as infection, asymmetry or nodules. Vascular occlusion is an uncommon but serious complication that requires prompt recognition and management. Increasing pain, pale or mottled skin, cool skin or visual symptoms after an injection require immediate medical attention.

The significance of a medical condition, medicine, allergy or previous treatment varies from person to person and according to the area being considered. An individual assessment is needed to review medical history, examine the skin and facial anatomy, and discuss whether treatment should proceed, be adapted or be postponed.
