New Filler Cohesivity Scale Improves Filler Results

Injectables are surging in popularity, thanks to their myriad benefits. Now a standardized scale of filler cohesivity, or how well the material sticks together, can help plastic surgeons use the best filler for each client. The researchers developed a standard test for comparing the cohesivity of HA dermal fillers. Samples of each filler gel were dyed, then squeezed into water and stirred using automated technology. A panel of plastic surgeon and dermatologist specialists experienced in using HA fillers then rated each sample’s cohesivity on an original five-point scale, known as the Gavard-Sundaram scale.Fillers are used to reduce facial lines and wrinkles; and restore volume, fullness and a youthful shape to the face, among other purposes. A wide range of HA fillers are available, and plastic surgeons try to match their individual properties to the purposes for which they will be used. But previously there was a lack of scientific data to support this matching process, including the rheologic (flow-related) properties of the various available products.Reaad more at American Spa.
