What are ceramides and how do they work?

Taking good care of our skin is one of the main ways we try to fend off the appearance of aging and fight wrinkles, but do you really know what happens to your skin as you age? 
How does aging affect skin?
Over the years a number of factors can take their toll on skin including diet, lifestyle and personal habits. As we grow older we often start to see the impact these have on our skin. For example, it might feel rougher to touch, less supple or even appear thinner1
Having a good skincare regime is something most of us try to adopt, especially as we age, but with so many products on the market it can be difficult to know what works best - and now there's a new ingredient that everyone's talking about: ceramides. 
What are ceramides? 
Ceramides are natural skin molecules in the top layer of the skin cells and play a key role in keeping skin hydrated2. As we age, our natural ceramide levels deplete meaning skin becomes dried and is more prone to redness3
There are, however, a variety of topical skincare products which contain ceramides to help to up levels, and these products can make a great addition to your anti-aging skincare regime. 
How do ceramides work?
Applying ceramide creams topically can help to restore the skin's barrier, meaning it retains moistuire and doesn't let water escape. 
By topping up ceramide levels you can  help reduce water loss and the appearance of wrinkles so your skin looks much more radiant. It will also help your skin look smoother, less dry and as if it has more elasticity4
What vitamins should I be taking to benefit my skin?
Aside from lotions and potions it's also a good idea to protect skin from the inside. You can do this by making sure you eat plenty of fruit and veg, which contain essential nutrients to keep your skin looking healthy and youthful. 
Top top up vitamins found in your diet, you may also want to consider taking a multivitamin that contains nutrients that support the skin. For example, Vitamin A and biotin help to support normal skin function, while vitamin C contributes to normal collagen formation for the normal functioning of skin.
