Overview
Hyaluronic acid injections are used to fill a wrinkle, restore volume or reshape a facial contour. The molecule occurs naturally in the skin, where it holds water. The injected gel is gradually broken down by the body, and it can be dissolved if needed with an enzyme called hyaluronidase.

Frequently asked questions
When will I see the result?
The effect is visible as soon as the session ends. Swelling can change how the area looks for the first few days, especially on the lips. The result is assessed 2 to 4 weeks after the injection, once the swelling has settled.
How long does it last?
On the lips, which move a lot, it lasts about 6 months. On more stable areas such as the cheeks, chin or folds, it usually lasts 6 to 12 months. It varies with the product, the area and the person.
What happens after the injection?
Swelling and redness are common for 2 to 5 days, and up to 10 days on the lips. Bruises may appear at the injection points and fade within 3 to 10 days. For 48 hours, avoid strong sun, saunas and intense exercise. Rarer complications are explained at the consultation.
Who should not have injections?
Injections are not advised during pregnancy or breastfeeding, with a skin infection in the area (such as cold sores or inflamed acne), or with an autoimmune disease that is not under control. Tell the doctor at the consultation if you take anticoagulants or have a known allergy.
