A sensitivity test should always be performed prior to the actual procedure. Because the body slowly absorbs the collagen, results usually only last one to three months although the procedure can be repeated as many times as desired.
Fat harvested from other areas of the body – usually the abdomen or thighs – can also be injected into the lips. One great advantage to this procedure is that there is no possibility of an allergic reaction, although as with collagen the results are temporary.
Other injectable lip plumpers include Artecoll, a synthetic material which augments the natural tissue to create long lasting results, Autologen (collagen from the patient’s own skin), which also has relative longevity and Dermalogen, which is extracted from the skin of a human donor then screened and processed to prevent the risk of disease.
The effects of the latter are relatively short term and similar to the effects of collagen.
Grafting: under local anaesthesia, material is inserted through incisions made in the inside corners of the mouth. The incisions are then closed with stitches.
Alloderm is a popular human donor material, which is strictly processed to prevent infection. The material
