Based on recent research, men appear to age faster than women. While women generally have a lower density of collagen in their skin, leading to a more noticeable appearance of aging, studies have shown that men's bodies age at a faster rate overall.
For example, a study at the University of Jyväskylä (Finland) found that men are biologically older than women. They observed that men's bodies are as much as four biological years older than females of the same age by their 50s. This difference is partially explained by men's higher levels of the mTOR (mammalian target of rapamycin) protein, which has been linked to aging and cell growth.
However, it's important to note that aging is a complex process influenced by various factors, including genetics, lifestyle, and environmental exposures. While men may age faster biologically, women may experience a more noticeable appearance of aging due to factors like hormonal changes and differences in skin structure.
Ultimately, the rate of aging varies significantly among individuals, regardless of gender.
