Cellular aging: senescence
At the core of aging is cellular senescence. Over the years, cells lose their capacity to divide, telomere lengths shorten, and mitochondrial efficiency decreases. This micro-level change manifests on the face as reduced collagen and elastin production, making the skin appear thin and loose. This process begins around age 25, and its speed is determined by genetic, environmental, and behavioral factors.
The best news here is that while modern medicine cannot reverse the senescence process, it can significantly slow it down. Photoprotection, antioxidant support, regenerative therapies, and a good lifestyle, when working together, can create up to a 10-year difference between "biological age" and "chronological age" in the skin.
Bone resorption and structural collapse
From the age of 40, facial bones, especially the maxilla, mandible, and orbital region, undergo resorption. This process does not appear as lines on the skin surface; however, it reduces the underlying support of the face. Under-eye hollowing, thinning of the cheekbones, and loss in the jawline—one of the most important reasons for all of these is bone resorption.
This information is critical because many patients who come with a complaint of "sagging" do not know that the solution is not skin tightening but rather rebuilding structural support. The correct filler plan does not lift sagging skin; instead, it puts the correct support back underneath and reverses the direction of facial pull.
Clinical note:Aging is not caused by a single layer; therefore, a single procedure is not the solution. Natural aesthetics means supporting multiple layers simultaneously, in a measured way.
Fat redistribution
While fat tissue is concentrated in the upper face in youth, it flows to the lower face with age. As the cheekbones thin, the jawline fullness we call jowls becomes more prominent. This redistribution gives the face a "tired" look. However, this is not actually a loss; it is a displacement. A good physician prefers to restore the displaced balance with support axes rather than surgically repositioning the shifted fat.
For this reason, in my clinic, I do not see aging merely as a "wrinkle list." The cause of wrinkles is not superficial but layered; the plan should be directed at this cause.
- In the skin: collagen loss, loss of function in elastin, thinning of the barrier.
- In the muscle: deep lines in hyperactive mimic muscles, sagging in weakened muscles.
- In the fat: loss in the upper face, accumulation in the lower face.
- In the bone: resorption in the maxilla and mandible, volume loss under the eyes.
- In the connective tissue: loosening of the retinacular ligaments.
Holistic view:Reading aging in the entire architecture of the face, rather than looking for it on the skin surface, is the first step in making natural aesthetic decisions.
