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 is presented as a transparent gel that is injected into the skin tissue to smooth fine lines, correct deeper wrinkles or restore facial volumes. This product is completely absorbable. It is not of animal origin but results from 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 drugs that modify blood flow (aspirin, anti-inflammatory drugs, etc.) in order to reduce the risk of hematomas. Anesthesia may be performed before treatment using an anesthetic cream or injectable xylocaine. The hyaluronic acid is placed with a fine needle in the dermis, under the wrinkle in order to raise the bottom of it. To restore volume to the face, the injection will be done more deeply and will be of a larger volume.
During the days following the treatment It is not recommended to expose yourself to extreme cold or intense heat (sunbathing, spa, etc.).
After the injection, there is usually slight edema and redness. The final result is visible after the edema has disappeared. The duration of the result depends on the type of hyaluronic acid used and the area treated. A new injection is usually necessary after 6 to 12 months.
