L’acide hyaluronique fait disparaitre le cerne creux et amélioré le bleu et le foncé.
Le cerne est une indication délicate et il est recommandé de choisir un médecin très expérimenté et formé à la technique.
It a difficult procedure because :
– Injections must be made at the correct depth.
The product is injected between the eyelid orbicular muscle and the bone, thus this is a deep injection.
– The doctor must not overcorrect the problem: it is better to carry out the injection in two goes.
– It is best to inject the acid via a cannula. Cannula injections allow us to avoid any vascular complications (the risk of complications is significant as this area is full of veins) and the patient is only jabbed once (needle injection requires several jabs).
– The correct product must be injected.
The hyaluronic acid used must be sparsely hydrophilic in order to avoid secondary oedema or swelling, so I use the Restylane range where the hyaluronic acids are amongst the least hydrophilic on the market (perhaps even the least hydrophilic on the market).
Depending on the sunken depth of the dark circle and the facial physiognomy, I inject a moderately reticulated Restylane hyaluronic acid, or even a very reticulated Restylane Perlane acid.
Technical faults can lead to overcorrection, a bluish effect (the Tyndall effect, due to the overly superficial placing of the hyaluronic acid), persistent bumpy surface irregularities, and permanent swelling (swollen eyelids). In this case, hyaluronidase injections offer a solution.
