Daxxify What Are Daxxify? Daxxify, also known as daxibotulinumtoxina-lanm or Daxi, was created by the Nashville-based company Revance Therapeutics Inc (Nasdaq: RVNC), and is a part of a family of neuromodulators that use injections of a small amount of botulinum toxin to smooth wrinkles for a more youthful appearance. Daxxify is used to treat dynamic wrinkles, meaning wrinkles that develop due to repeated muscle movement. Daxxify has received FDA approval specifically to treat the glabellar lines, also known as frown lines, that appear as vertical lines on the forehead extending upward between the eyebrows. Daxxify is the first botulinum toxin injectable treatment made up of a synthetic, proprietary Peptide Exchange Technology, meaning it does not have any human or animal products. Daxxify is the newest neuromodulator to last up to 9 months.
