（2025·江苏·二模）“If your skin is getting older, you are getting older, so be careful,” says Claudia Cavadas at the University of Coimbra, Portugal. Could our fight to remove wrinkles help restore youth both inside and out?
As skin ages, more and more cells enter a lifeless state called senescence (衰老). As time marches on, the mechanisms (机制) for clearing senescent cells out start to decline and they build up in tissues. This is bad news. The build-up of these cells has been shown to be a direct cause of some of the conditions that are generally more common in older age.
To support her assumption around wrinkles driving whole-body ageing, Cavadas is planning to test experimental drugs on animal models of aged skin. “The evidence is still fragile, but, in a year, we will have experimental data” she says.
Whether resisting skin ageing resists whole-body ageing will need to be seen. But there is another good reason to slow down skin ageing at least. Aged skin is worse than young skin at pretty much everything it is supposed to do, says a plastic surgeon. Its barrier functions weaken, wounds are slower to heal (康复), sensitivity to touch declines and its ability to defend diseases is weakened.
How about anti-wrinkle creams? At present, there is limited evidence that they are genuine anti-ageing treatments. We do, however, have one method for preventing skin ageing: sunscreen, which absorbs UV rays before they do damage to the skin. It is never too soon to start. Even though the first visible signs of skin ageing usually don’t appear until our mid-20s, the potential processes are under way much earlier.
Apparently, wrinkle treatment should no longer be seen as a “skin-deep” thing, but as a vital part of staying biologically young and healthy. Everyone should pay attention to that, because we all have skin in this game.
