In addition to changes in the appearance of our skin and volume of facial fat, our skulls change with time. These changes contribute to our aged appearance.
Our skulls are just one of the things that change as we age. There are many other changes that occur with aging.
Know this: Science has identified how our skulls change with age and several articles have been written on the subject.
The main areas that morph are our eye sockets (orbital rims) and cheekbones. These changes mostly affect the central part of our face.
As infants, the central part of our face is relatively compact. As we become young adults, more space develops in that middle part of our face. With maturity, however, changes in our orbital rims and cheekbones make our central face more compact again and closer to the proportions of infancy.
The picture above highlights the differences between the skulls of a young and older person. *
As our central face becomes more compact, the muscles, fat, and skin attached to the bones bunches together to a certain degree. What this translates to is illustrated by the following picture. This picture shows a great example of both a young and aged face with almost no overlying fat. You can clearly see the differences in the shapes of the underlying skeleton and how the skin of the older face wrinkles and folds because there is less bony support. **
Knowing how our skull changes with age, we can combat the signs of aging by addressing the underlying problem. Fillers like Sculptra and Radiesse, muscle relaxers including Botox, and various lasers give us the upper hand. The more we learn about how all aspects of our face change with age, the better we can become at rejuvenating it.
