The loss of collagen and elastin from the skin’s structure as we grow older is a natural process, leading to the development of lines and wrinkles, along with lost volume and hydration resulting in sagging and altered facial definition as the skin has lost its ability to ‘bounce back’ and retain its natural position.
This is particularly noticeable along the jawline, whereby the effects of gravity mean the skin is less able to support the weight of the facial tissue and subcutaneous fat under the skin, and the development of facial sagging or jowls can occur. Weight loss can also be a contributing factor to a sagging face, where the skin has stretched out over a period of time and is no longer able to return to its more youthful, tighter state.
