HOW WE AGE
For humans our face has always been the focus when it comes to the process of the enhancing of features, be it simply with make up or more dramatically surgical intervention. Over time our knowledge and understanding of the facial anatomy & the way skin ages has enabled us to successfully treat ageing concerns more effectively. There has been major progression over the last 2 decades & advances in clinical interventions have enabled us to treat the root causes of ageing before it happens, or even reverse premature & accelerated ageing
Our face plays crucial role in many human traits of society. It can influence how we are accepted & received in day to day life. It creates an impression of our potential age, ethnicity, social status, traits of personality, mood, demographic, hobbies & habits!
The ageing process is often not as noticeable in other parts of our body as it is in our face as our faces are stimulated by expression, emotion & the bare the brunt of extreme weather in hot and cold climates.
The opportunity to look younger is no longer just accessible to ‘rich and famous’ but to the vast majority of people worldwide in varying capacities. Social media means that we have never been as educated or as informed about treatments available to us and what to expect from them.
Regardless of how beautiful an individual was in their youth, the ageing process can strip attractiveness as we progressively mature. A loss of volume and proportion can be observed over the course of time.
When considering the anatomy of the face for rejuvenation with injectables, it is helpful to think of it in its entirety as a three-dimensional structure that consists of five unique layers running superficial to deep. This is important, so that we know which structures we are aiming to treat & the success we will gain from each approach
We must remember, that the ageing process effects not only the most visible part of our face, the skin, but also other intrinsic factors that are at play including deep fat layer loss as well as los of muscle laxity & ligament and bone deterioration dramatically accelerate ageing.
The first layer, the outer most layer of the face is the skin, comprises of both the epidermis and dermis. Beneath this you will find the subcutaneous layer that comprises of fatty tissue. The subcutaneous layer sits on top of the fascial layer that varies depending on the area of the face. For example, in the forehead the fascial layer contains the frontalis muscle, the temporal region contains the temporal parietal fascia and below the zygoma in the mid and lower, the fascia becomes the SMAS (superficial muscular aponeurotic system) which is fibro fatty and lymphatic fascial tissue that contains the muscles for facial expressions.
Underneath the SMAS layer is a layer that has traditionally been considered to be a loose areola tissue layer. We now understand that this deeper layer comprises of multiple discrete fat compartments and can be sometimes referred to as the deep fat layer. Beneath this is the periosteum of the facial skeleton.
