Biological aging mechanisms and cellular health insights

Medical experts are providing new perspectives on the biological processes of aging, emphasizing that cellular decline begins much earlier than social perceptions suggest. Dr. Javier Coindreau, Director of the Center for Medical Sciences of Longevity, notes that human biological aging typically begins around age 35, marked by a gradual loss of tissue, muscle mass, and bone density.

To mitigate the impact of this decline, specialists recommend reaching peak physical condition and strength in younger years to ensure greater functional independence later in life.

In the field of dermatology, Dr. Lidia Maroñas highlights the importance of cellular health, specifically the role of the molecule NAD+. This molecule acts as fuel for cells, aiding in energy production, DNA repair, and the activation of longevity-related proteins. As NAD+ levels naturally decrease with age—a process accelerated by UV radiation and oxidative stress—the beauty and medical industries are increasingly focusing on internal cellular repair rather than just treating surface-level wrinkles.
