We’ve all seen wrinkles. Whether it’s in our own mirror or on someone else, everyone is familiar with those creases, folds or ridges in the skin. But what causes wrinkles? Why is it almost inevitable that we will all get them one day? Join us as we dive into some of the science behind wrinkles.
As we become older our skin gets thinner, drier and less elastic. Our skin’s ability to protect itself from damage is also reduced as we age. Eventually, wrinkles, creases and lines form on our skin. The top two layers of the skin, the epidermis and the dermis, are where wrinkles occur.
Epidermis – The epidermis is the outer layer of your skin. It acts as a barrier, protecting your body from harmful elements in our environment. Your epidermis is replaced about every 60 days. As we age, the epidermis takes longer to renew, and those old skin cells build up on the skin, causing those tell tale signs of aging.
Dermis – The dermis is the middle layer of skin. It is fed by blood vessels, and contains collagen and elastic fibres that are crucial to young looking skin. As we age, the amount of collagen and elastic fibres in your dermis diminishes, which causes your skin to sag due to the decrease in elasticity. Fibroblasts are also housed in the dermis layer, and these are collagen making machines. After around the age of 40, fibroblasts ability to produce collagen starts to decrease, leading to those fine lines and wrinkles.
Other Factors That Can Cause Wrinkles
There are a number of other factors that add to the slow down/destruction of collagen in your skin. Some of them are in our control, and some aren’t!
Sun Damage – unprotected exposure to the sun’s rays destroys collagen and elastin, which will cause wrinkles to surface much sooner. Sunburns are caused by UVB rays. They have a short wavelength which means that they can burn the top layer of our skin but can’t penetrate deeper into the dermis. UVA rays have a longer wavelength and penetrate into the dermis layer. These UVA rays degrade the collagen holding our skin together, which leads to wrinkles.
Genetics – Your skin colour effects how you handle sun damage. Lighter skin tones tend to be more vulnerable to the suns impact, which then accelerates the development of wrinkles. There are also other genetic factors to consider, like if your parents developed wrinkles early in life.
Facial Expressions – People who repeatedly smile, frown, or squint will develop fine lines and wrinkles earlier than other who do not. When you are young, your skin is able to spring back from these facial expressions, but as we get older our skin loses its flexibility, making it harder to spring back. This lack of flexibility and strength allows more permanent grooves to form on your face.
Hormone Loss – As you go through different stages in life, your hormones change (for example, menopause). Sometimes, these changes in hormones can affect your skin’s elasticity. You might find that your skin becomes thinner and doesn’t bounce back when pinched.
So What Do You Do?
While there isn’t a quick fix for wrinkles, by taking care of your skin you can hold them at bay for as long as possible. Protect your skin from the sun, and make sure you exfoliate regularly.
