What contributes to intrinsic aging in the skin?

Intrinsic aging in the skin is primarily influenced by genetic factors. This type of aging is a natural process that affects everyone and results from the body's biological clock. As individuals age, their skin undergoes changes such as decreased collagen production, slower cell turnover, and reduced moisture retention, largely due to genetic predispositions.

While sun exposure, poor diet, and smoking are significant contributors to extrinsic aging, which involves environmental and lifestyle factors leading to premature skin aging, intrinsic aging is fundamentally tied to genetics. It encompasses the natural aging process that manifests over time regardless of external influences, allowing for a clearer understanding of how our inherited traits play a crucial role in skin aging.
