Researchers develop, validate lip-fullness scale
As lip-augmentation procedures become more popular, validated measures of lip fullness become more necessary for quantifying outcomes.
With this in mind, a team of researchers led by Wm. Philip Werschler, M.D., associate clinical professor of medicine/dermatology at the University of Washington, set about developing a scale for rating lip fullness that would accurately assess clinically meaningful differences. What they developed was two: The initial Allergan Lip Fullness Scale (iLFS) and the revised Allergan Lip Fullness Scale (LFS), the latter of which was expanded to include photographs of lips as well as lips from various ethnicities.
