Facial Implants


What are injectable implants?

Injectable implants are mainly used in the facial region, though they can also be beneficial in other parts of the body and they are used to fill:

  • Wrinkles and age lines: in the face, lips, the corners of the mouth, the brow, neck, around the eyes or the mouth.
  • Deep wrinkles: nasolabial (from the nose to the mouth) or glabellar (lines between the eyebrows).
  • Acne scars: chickenpox or other conditions.

Or else to add volume:

  • In the lips, cheeks, chin, jaw, jaw angles, etc.
  • For patients being treated against HIV.
  • When there’s a facial atrophy or asymmetry.

What type of fillers are there?

A filler is any product used to provide volume to a part of the body. Among those fillers we can separate them in two main groups: grafts and implants.

The first ones are removed from the body of the individual and then taken to another part of the body, without maintaining a vascular connection with the donor area (a patient’s own fat graft, autologous grafts), tissues from another individual of the same species (another person’s cartilage graft, homologous grafts) or of a different species (a cow’s skin, cartilage and collagen, heterologous).

On the other hand, an implant is an object of non-organic material introduced in the body. Many materials have been used to this end: wax, ivory, and in more recent years, plastics (polyurethane and polyethylene), elastomers (silicone and methacrylate), expanded polytetrafluorethylene (PTF-E), metals (titanium, vitalium, gold and steel) and textile products (Dacron, Teflon and Gore-Tex).

Implants should be used in cases of hypotrophy, atrophy or loss of tissue, both for soft tissue and bones, when there is no possibility of obtaining the material from the patient’s body, or when it is not justified because it would be very difficult to obtain it or the results achieved with the implant cannot be surpassed.

Materials of the injectable fillers: Implants

These are materials which may be inserted in the body through an injection. According to the origin, they are classified among biological (organic) and non-biological (synthetic) and according to their life-time: absorbable and non-absorbable. Since this is, for us, the most important feature of an implant, we will choose this classification to study different products.

  • Absorbable implants: Temporary injectable fillers, which are quickly biodegradable, have a lifespan of 2 to 6 months at most. The most frequent materials used are those derived from collagen (autologous or bovine) or from hyaluronic acid (biological or synthetic). Polylactic acid is another absorbable product (formerly called New Fill and currently Sculptra) which lasts 12 to 18 months.
  • Non-absorbable implants: These are definitive, which means, they are non-absorbable: Methacrylate (Artecoll and Dermalive), Acrylamide (Aquamid and Evolution) and Polyalkylimide (Bio-alcamid). Liquid silicone, in the shape of micro-grains or bio-polymers belongs to the synthetic non-absorbable materials, and its use is forbidden in Argentina.
