As we get older, the natural production of collagen and elastin in our skin slows down, causing the skin to lose its elasticity and firmness. Facial features such as the cheekbones and jawline become less defined over time.‘Jowls’ – the sagging skin on the lower face and neck – are two of the most disliked aspects of skin aging. The skin under the jaw sags as well, leading to the dreaded ‘double chin’ look. Jowls are a natural sign of the aging process and may be accelerated by factors such as over exposure to the sun and smoking. Changes in bone and muscle structure can also contribute to this condition. Fat accumulation may also occur. There is also a genetic factor influencing the mechanics of these changes.
