Cosmetic Injectables

Dermal Fillers

Many methods and substances have been used to treat facial wrinkles and to conceal the effects of ageing on the face. In addition to formal surgical procedures, laser treatment and botulinum toxin there are a large number of fillers available which can be injected.

Types: Dermal fillers may be biocompatible or synthetic and are marketed alone or in combination.

Biocompatible fillers have a perceived safety record and are resorbable. However, the period of benefit is of limited duration normally lasting about 6 months. Synthetic fillers are permanent but are associated with rejection, migration and granuloma formation and are unable to change with the ageing face. In the case of an adverse reaction removal is almost impossible to achieve. There are few indications in current practice for the injection of synthetic fillers to the correct lines and effects of ageing.

The AAIC ONLY endorse dermal fillers made from Hyularonic Acid and with FDA approval or CE Kite mark.

Biocompatible Fillers

Ideally the effects of a filler should last about 12 months. This allows reasonable, well-adjusted healing time from the injections and also enables accommodation of changes in the face which may occur with continued ageing.

Collagen

Collagen implants are prepared from three sources: bovine, human or autologous. Collagen synthesis may also be increased by fibroblast stimulation or injection of cultured cells.
NOTE – Not endorsed by AAIC

Human Preparations – These are a preparation of human collagen, elastic fibres and other dermal components from screened donors. No pre-treatment skin testing is necessary and the effects last from 3 to 12 months
(recommended to be performed by a PLASTIC SURGEON).

Autologous Preparations – These require skin harvest, which is processed into a collagen suspension for injection and requires 2-3 treatments over a 3 month period. This is reported to provide greater than 75% correction for more than a year.
(Recommended by a registered PLASTIC SURGEON)

Injectable Fibroblasts can be cultured from a small skin biopsy and following a test dose at one month a series of 3 injections is given at 2 week intervals. Gradual improvement occurs over 6 months and repeat injections can be prepared as required from the original biopsy.
(Recommended to be performed by a registered PLASTIC SURGEON)

Polylatic acid stimulates fibroblast production. The effect takes 4 to 6 weeks to achieve but can last for years. This should not be injected superficially as obvious fibrous nodules can result which may be difficult to treat.
(Recommended to be performed by a registered PLASTIC SURGEON)

Hyaluronic Acid

Hyaluronic acid preparations (hyaluronan) are obtained by bacterial synthesis or from an avian source and are cross linked to varying degrees to maximise viscoelasticity and persistence. They last between 6 and 9 months and although well tolerated there is a 1% incidence of adverse reactions including granulomatous inflammation and sterile abscesses.
ENDORSED by AAIC as the preferred method of adding dermal fillers to the face, decliotage and hands.

Synthetic Permanent Dermal Fillers
(Recommended to be performed by a registered PLASTIC SURGEON ONLY)

Methylmethacrylate has been used for many years as bone cement for joint replacement surgery. However, in the skin redness, inflammation and infection may occur. One preparation utilises Methylmethacrylate microspheres suspended in bovine collagen whilst an alternative suspends them in Hyaluronic acid. These are intended to permit even distribution of the microspheres prior to absorption of the collagen or Hyaluronic acid. A series of injections are required to achieve the final result and allergic reactions to collagen may occur.

Polyacrylamide Gel is used alone or in combination with polyvinyl microspheres. The injected volume is reported to diminish by one third post injection and then build up again over the next 2 months. The augmentation is supposed to be permanent but additional injections may be required. This augmentation tends to stay soft but Polyacrylamide gel can act as a reservoir for bacteria and has been associated with a significant delayed infection rate.

Silicone Injections are banned in most countries but are still used in France and Italy. Although giving apparently excellent initial results, migration and inflammation are almost inevitable and the surgery then required is likely to result in much greater aesthetic deformity than that leading to the initial treatment.
