Why a woman's face ages faster than a man's after she reaches menopause: loss of sex hormone estrogen speeds up wrinkles and sagging
- Researchers used computers to map the changes in men's and women's faces
- Nearly 600 parts of the face were measured in subjects aged 26 to 90
- Researchers found similar changes in men and women up to around 50
- But after 50 years the age-related change suddenly increased in women and not in men
Time, they say, seems to be speeding up as we get older.
And it seems that the same thing happens with the aging process.
Now scientists have found what most older women already suspected – that the speed at which their faces become wrinkled and limp becomes faster when they reach the age of 50.
Researchers used computers to measure and map the changes in nearly 600 different parts of the face in men and women between 26 and 90 years old. They found similar changes between the ages of 40 and 50.
Researchers from the University of Vienna studied nearly 600 points on volunteer faces with the help of computers to map the effects of aging on men and women between 20 and 90. The researchers discovered that women's faces & # 39; faster & # 39; were older than a man of the same age once they hit menopause
When women reach menopause, the loss of estrogen affects the production of collagen, which affects the elasticity of the skin. Women also suffer from less defined cheekbones and shrinkage of the chin
But after 50 – the average age at which menopause begins – age-related changes suddenly accelerated in women. They quickly experienced noticeable differences, such as their eyes appearing smaller, the nose and ears getting longer and faces becoming flatter due to a loss of fat and thinning of the skin.
The & # 39; peak & # 39; in the process it continued to 60, after which it became quieter again. The acceleration is believed to be related to the loss of the sex hormone estrogen after the menopause. It has widespread effects on the protein collagen, which makes the skin elastic.
It also ensures that bone is re-absorbed, resulting in less defined cheekbones and a decrease in the chin.
Researchers from the University of Vienna and others analyzed the faces of 88 men and women in the study. They then scanned 585 measurement points on the face and compared the differences in faces between adults of different ages.
In both sexes, they said, the characteristics of aging were generally similar and included flatter face, sagging skin, deeper lines between the nose and the corner of the mouth, smaller visible parts of the eyes, thinner lips, and longer nose and ears. But even before the age of 50, experts discovered that women's faces age twice as fast as men. Between 50 and 60 it was & # 39; aging path & # 39; up to three times faster.
Sonja Windhager, who led the research, said: & Men and women age the same way up to the age of 50. It is a linear progression. But at the age of 50 things are going very fast for women. It does not accelerate at 50 for men. & # 39;
The researcher added: & # 39; After the age of 50, the age at which you have the menopause is the best predictor of how old you look. The onset of menopause varies considerably among women.
& # 39; On average, it is around the age of 50, with a variation of about ten years, with on average a number of women from 40 and some up to 60. This appears to determine the face shape more than the actual age. & # 39;
About 30 percent of the skin collagen is lost in the first five menopause years. In the study, none of the women used hormone replacement therapy.
However, it could be a way to prevent some of the age-based acceleration, experts said.
The research, published in the American Journal of Physical Anthropology, could also help crime scenes to more accurately reconstruct faces of human remains.
