Citrus Compounds as a New Direction for Combating Skin Aging?

Aging is a complex biological process that arises from the combined influence of multiple factors. One of the most frequently discussed mechanisms involves the gradual shortening of telomeres, the structures located at the ends of chromosomes. Each time a somatic cell divides, these telomeres shorten slightly. Eventually, when they become critically short, the cell can no longer continue dividing and enters a senescent state. Beyond telomere shortening, many additional factors contribute to aging, including DNA damage, increased oxidative stress, and chronic inflammation. Among these influences, oxidative stress is particularly important in the aging process.
