How skin hydration is linked to aging

Did you know that healthy skin contains around 10-20% of water? If this level drops below 10%, your skin is considered dehydrated. If you’ve ever marvelled at how some not-so-young celebrities appear much younger than they are, there’s a good chance it can be attributed to well-hydrated skin.

Skin that isn’t properly hydrated can result in an increase in fine lines, wrinkles and sagging skin due to it losing its elasticity, meaning it can’t snap back into place as easily as before. It also means that it is less effective as a wall of protection for the lower skin layers, resulting in more sensitive skin that is much more reactive to outside elements such as dust.

Too much alcohol, smoking and sun exposure can also lead to dehydration, which will exacerbate skin imperfections as gaps are created in the protective layer of skin, allowing moisture molecules to escape. This will lead to your skin appearing dull and lacking that “healthy skin” glow, and may even start to become rough and cracked. Needless to say, it’s not how you want your skin to look like!

So how do you ensure that your skin remains hydrated, healthy and youthful-looking? It all boils down to maintaining good habits and a healthy lifestyle. You can play your part by drinking plenty of water and eating foods rich in vitamins C (citrus fruits), D (salmon) and E (leafy vegetables), getting plenty of sleep each night and avoiding prolonged exposure to the sun.

However, it is also highly recommended that you invest in skincare products that help to retain moisture in your skin. If all it takes to maintain well-hydrated skin is drinking bottles and bottles of water, everyone would be doing it but unfortunately it’s a little bit harder than that!

Look out for skincare products that contain humectants (substances that reduce moisture loss) like propylene glycol and sodium PCA; these help to bind water to your skin.
