44 is the average age that people begin to
notice the appearance of fine lines and wrinkles.
Before the age of 44, the most common skin
issues are spots and breakouts, dry skin and blackheads. Once we reach 44,
wrinkles, fine lines and signs of ageing becoming the primary skin concerns.
According to the customer survey of over 300 women
and men, the average age we start to notice fine lines, wrinkles and signs of
ageing is 44. Our body ages most rapidly between 44 and 60
“We’re not just changing gradually over time.
There are some really dramatic changes,” said Prof Michael Snyder, a geneticist
and director of the Center for Genomics and Personalized Medicine at Stanford
University and senior author of the study.
“It turns out the mid-40s is a time of dramatic
change, as is the early 60s – and that’s true no matter what class of molecules
you look at.”
Researchers assessed the changes of 135,000
different molecules (RNA, proteins and metabolites) and microbes (the bacteria,
viruses and fungi living in the guts and on the skin of the participants).
The abundance of most molecules and microbes did
not shift in a gradual, chronological fashion. The transformations tended to
occur when people were in their mid-40s and early 60s in both women and men.
“This suggests that while menopause or
perimenopause may contribute to the changes observed in women in their mid-40s,
there are likely other, more significant factors influencing these changes in
both men and women,” said Dr Xiaotao Shen, a former postdoctoral scholar at
Stanford medical school and first author of the study.
The first wave of changes included molecules
linked to cardiovascular disease and the ability to metabolise caffeine,
alcohol and lipids. The second wave of changes included molecules involved in
immune regulation, carbohydrate metabolism and kidney function. Molecules
linked to skin and muscle ageing changed at both time points.
The pattern fits with previous evidence that the
risk of many age-related diseases does not increase incrementally, with
Alzheimer’s and cardiovascular disease risk showing a steep uptick after 60. It
is also possible that some of the changes could be linked to lifestyle or
behavioural factors. For instance, the change in alcohol metabolism could result
from an uptick in consumption in people’s mid-40s, which can be a stressful
period of life.
The findings could help target interventions, such as increasing exercise during periods of more rapid muscle loss, the authors said.
“I’m a big believer that we should try to adjust our lifestyles
while we’re still healthy,” Snyder said.
