Hyaluronic acid removes the hollow ring/ dark cricle and improves the blue and the dark. The ring is a delicate indication and it is recommended to choose a very experienced doctor trained in the technique. This is a difficult indication because:
- You must inject at the right depth and have a perfect knowledge of the anatomy of this area. The product must be injected between the orbicularis of the eyelids and the bone, so the injection is deep.
- Do not overcorrect, it is better to inject in two or more sessions.
- It is better to inject the acid via the cannula. Injection into the cannula avoids any vascular complication (this anatomical area is highly vascularized, the risk of complication is important) The patient is injected only once instead of various times, (needle injection requires multiple stings). Depending on the stage of the ring, we will inject all or part of the sub-ocular hollow triangle.
-The Doctor must inject the right product. The hyaluronic acid used must be slightly hydrophilic so as to avoid any secondary edema. For that I use the Restylane range whose hyaluronic acids are among the least hydrophilic on the market. Depending on the digging of the ring and facial physiognomy, I inject a hyaluronic acid moderately reticulated type Restylane or very reticulate type Restylane Perlane. The failures exist in case of technical fault, one can have over-corrections, a bluish effect (it is the Tyndall effect, due to the superficial placement of the hyaluronic acid), persistent irregularities of surface type hump, a permanent edema (swollen eyelids). But rest assured, in the hands of your experienced doctor, such inconvenience is extremely rare.
