Dermatologists define premature ageing as when individuals show signs of ageing, like wrinkles, age spots, or fine lines, before age 35. Researchers don’t have one answer for what causes us to age, but they can agree on one thing: it’s a combination of genetic and environmental factors.
Genetic factors cause “intrinsic ageing.” This is what naturally occurs as you get older. Intrinsic ageing is largely out of your control, since it’s controlled by your genes.
Have you ever known someone whose hair turned gray super early, just like their dad’s did? That’s intrinsic ageing at work.
Signs of intrinsic ageing include thinning skin and fine wrinkles. Some products can boost skin tightness or hide wrinkles, slowing intrinsic ageing, but there’s no way to completely stop it.
“Extrinsic ageing,” on the other hand, is caused by factors such as pollution, lifestyle, sun exposure, and diet. Signs of extrinsic ageing include rough skin texture and coarse wrinkles.
Because extrinsic ageing is influenced by the choices you make, it is largely preventable if you protect your skin throughout your lifetime. That’s good news, since extrinsic ageing is entirely to blame for premature ageing. After all, since intrinsic ageing is naturally defined by our genes, it could never be “premature.”
