Today's nonsurgical rejuvenation tools provide effective means for achieving objectifiable contemporary standards of facial beauty, an expert says.
But good outcomes still rely on the physician's aesthetic judgment and skill, says Steven Liew, M.D., a Sydney, Australia, plastic surgeon who is medical director of Shape Clinic.
Eye of the beholder
The Phi mask developed by Stephen Marquardt, M.D., attempts to introduce 20th-century objective measurements to facial beauty concepts, but it's an extremely complex model that has proven impractical for daily use, Dr. Liew tells Dermatology Times.
Conversely, he says that a more universal concept of facial beauty would help physicians and patients readily identify why one face is more attractive than another.
"Human eyes are fairly primitive," he says. When viewing faces, people notice skin color and texture first, then facial shape, followed by individual facial features, Dr. Liew says.
Common facial shapes include round, square, oblong, heart-shaped and - the ideal shape - oval, he says.
The ogee curve
More specifically, he defines the ogee curve as a concave arc flowing into a convex arc, forming an S-shaped curve with vertical ends.
"The ogee curve is a three-dimensional concept," Dr. Liew says.
As faces age, they generally experience a flattening of this curve, he says. Therefore, Dr. Liew says, "Any rejuvenation procedure, be it a filler, Botox (botulinum toxin A, Allergan) or other procedure, should restore the ogee or, in some cases, accentuate the existing ogee."
