A recent analogy of facial aging spoken at a conference compares our faces to a pillow. Our facial volume is like the spongey core of the pillow, which loses shape and dimension over time. Our skin is the fabric over the pillow becoming more wrinkly over time.
While this analogy may have some merit, most patients do not want to be called a “pillow face”. This is a derogatory term used when the face is overly injected with filler.
Obviously, there are many anatomical and aesthetical nuances of the face which the injector has to relate so that the face appears both refreshed and natural.
