This dermal filler is made of hyaluronic acid that can correct deep wrinkles, contour facial features, or add volume to lips. Sinclair Pharma uses E-brid technology to cross-link the hyaluronic acid in this filler, which forms covalent bonds between and within the particles. This results in hyaluronic acid that has undetectable levels of BDDE, a cross-linking agent. Since some doctors have concerns about how BDDE may affect the body, the low levels in this hyaluronic acid gel can help make your patients feel more at ease with their treatment.
