Hyaluronic acid is a substance naturally present in the skin. It is a polysaccharide whose main function is to hydrate the dermis. The finished product is supplied in pre-filled ampoules. It appears as a transparent gel that is injected into the skin tissue to smooth fine lines, correct deeper wrinkles, or restore facial volume. This product is completely absorbable. It is not of animal origin but is the result of a synthesis. It has been used for many years without risk in various therapeutic applications in ophthalmology and rheumatology.
Principle of hyaluronic acid injection
One week before the injection, it is recommended not to take medications that alter blood fluidity (aspirin, anti-inflammatories, etc.) in order to reduce the risk of hematomas. Anesthesia can be administered before treatment using an anesthetic cream or injectable xylocaine. Hyaluronic acid is placed with a fine needle in the dermis, under the wrinkle in order to lift the base of it. To restore volume to the face, the injection will be made more deeply and will be of a larger volume.
During the days following treatment, it is not recommended to expose yourself to extreme cold or intense heat (sunbathing, spa, etc.).
After the injection, there is usually slight swelling and redness. The final result is visible after the swelling has disappeared. The duration of the result depends on the type of hyaluronic acid used and the area treated. A repeat injection is usually necessary after 6 to 12 months.
