Solid hyaluronic acid provides more precise wrinkle correction, study finds.
Plastic surgeons have developed a solid hyaluronic acid filler that is instantly reversible and offers a more precise correction of wrinkles than its popular gel counterpart, reveals a study. "This novel technology has significant advantages over injecting fillers in gel form," said Geoffrey Gurtner, MD, ASPS Member Surgeon and study lead author.
Soft tissue fillers accounted for 1.8 million of the 11.6 million cosmetic minimally-invasive procedures performed in 2010, according to the ASPS. Hyaluronic acid was the most popular soft tissue filler, with more than 1.2 million procedures performed.
Hyaluronic acid soft tissue fillers are traditionally administered in gel form, and though highly effective for treating most deep wrinkles and folds, are not optimal for reducing fine wrinkles such as crow´s feet or long horizontal wrinkles along the forehead, the study reports.
To address these needs, the authors turned hyaluronic acid into a solid thread, the size of a fine strand of hair, which was then placed under wrinkles using a fine needle. Since the filler is solid, it can be easily removed and the results are immediately reversible. Within a few hours, the solid thread hydrates, swells and reverts back to a soft gel similar to existing gel fillers. (SOURCE: Sociedad Americana de Cirujanos Plásticos /ASPS)
