In order to understand your facial analysis, it is helpful to know some basic principles. Leonardo da Vinci explained that the face, ideally, can be divided up into equal one-fifths in the vertical dimension and one-thirds in the horizontal dimension. If, for example, the nose is wider than one-fifth of the horizontal dimension, then it could make the face look out of proportion. Improvement, in certain instances, might be obtained by narrowing the nose.
From the side view, one might look to see if the chin or nose are in proportion and are aligned properly. Ideally the position of the chin should be near a line dropped from the lower lip. A weak chin, for example, might detract from the profile appearance, and, in this case, a chin implant might improve the deficiency.
Also, it is important to understand that perfect symmetry of the face or body is rare; one side is usually different than the other. There may only be a minimal difference that most people never detect, or there may be obvious differences in symmetry. During embryonic (fetal) development, the two sides of the face develop separately and the later merge in the midline. Knowing this, one can understand how the two halves are rarely exactly alike or symmetrical. These minor differences in facial structures are considered perfectly normal. Analyze your own face in the mirror before your consultation in order to aid your understanding of your analysis.
