Based on my personal experience in general I am not in favour of permanent fillers: the only exception are a few products specifically indicated to fill fat atrophy areas in the face in HIV patients.

My choice basically depends on two factors: it has not yet been proven what will happen to these injectables after 15-20 years and secondly the fillers could migrate towards a non ideal position due to skin aging and tissue sagging.

One must also remember that surgical use of permanent products such as liquid silicone and Teflon is forbidden in Italy because of the very high risk of complications (migration of product, chronic inflammatory reaction, onset of cancer) and because they are extremely difficult to remove once the widespread migration into tissues has occurred. Temporary fillers include collagen, hyaluronic acid and autologous fat (from the patient). Fat injections will be treated in the chapter on Liposculpture.

Before performing treatment with collagen it is advisable to perform an injection test to evaluate possible allergic reactions to the product. The patient should always remember to ask the surgeon for a copy of the label of the product to be certain of the type of product that has been injected and where it comes from.
