Hyaluronic acid is a substance naturally present in the skin. It is a polysaccharide whose main function is hydration of the dermis. The finished product is supplied in pre-filled ampoules. It comes 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 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 medication that alters the fluidity of the blood (aspirin, anti-inflammatories, etc.) in order to reduce the risk of bruising. Anesthesia may be performed prior to treatment using numbing 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 deeper and will have 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, a slight edema and redness usually occur. The final result is visible after the disappearance of the oedema. The duration of the result depends on the type of hyaluronic acid used and the treated area. A new injection is usually needed after 6 to 12 months.
