Dermatologists define premature aging as when individuals show signs of aging, 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 aging.” This is what naturally occurs as you get older. Intrinsic aging 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 aging at work.
Signs of intrinsic aging include thinning skin and fine wrinkles. Some products can boost skin tightness or hide wrinkles, slowing intrinsic aging, but there’s no way to completely stop it.
“Extrinsic aging,” on the other hand, is caused by factors such as pollution, lifestyle, sun exposure, and diet. Signs of extrinsic aging include rough skin texture and coarse wrinkles.
Because extrinsic aging 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 aging is entirely to blame for premature aging. After all, since intrinsic aging is naturally defined by our genes, it could never be “premature.”
