You may have heard about
biological age and
chronological age, but what do these terms really mean, and why are they important for your skin? Chronological age is straightforward—it’s just the count of years lived, marked by each birthday. On the other hand, biological age refers to how old your body and its cells actually feel and function, influenced by the cumulative damage they've sustained over time.
Compared to chronological aging, biological aging is much more complex and is shaped by genetics, environmental factors such as sun exposure and pollution, and lifestyle choices like diet, exercise, social interactions, and supplementation. These factors can modify gene expression through epigenetic changes, affecting crucial processes like collagen and elastin production, which are essential for maintaining youthful skin.
Within this perspective, skin longevity aims to slow down biological aging by addressing the underlying cellular and molecular damage. This includes targeting DNA damage, which many researchers believe is a central cause of aging. DNA, the blueprint of all cellular functions, can be affected by both internal and external factors, impacting everything from cell repair to replication. By minimizing DNA damage and promoting repair mechanisms, longevity skin care can help preserve your skin's youthful appearance, regardless of your chronological age.
