The appearance of our skin is constantly changing and age, diet, pollution and sun all play a part in this.
If hoping to achieve healthy, glowing skin at any age, an expert shared some foods to add to your trolley, including nuts and fish.
Registered nutritionist Dr Lucy Williamson advised Britons to look for foods that are naturally high in skin-boosting vitamins.
This includes meals high in healthy fats and omega-3 as studies have shown this can improve hydration and reduce the signs of ageing.

Dr Williamson said: "Increase your healthy omega oils, especially omega-3 and omega-7. That means enjoying more fish, one of the very best sources of omega 3, and of course plants like walnuts and flaxseed."
The expert also praised foods high in zinc and vitamin C and E as these can all help to rejuvenate skin. Zinc has many benefits but it is often credited for helping the production of collagen and elastin.
Both of these proteins help to tighten the appearance of skin and can even reduce sagging, therefore making you look years younger.
Again, nuts and fish are a great source of these nutrients. Dr Williamson continued: "There’s a new kid on the block called sea buckthorn.
"It is a bright orange super-berry packed with omega-7, vitamin C and E and fabulous for skin health.
"Zinc is another important nutrient for healthy skin - seafood, nuts and whole grains are great sources."
The expert also recommended filling up on plenty of healthy fruits and vegetables, as well as fermented foods, if looking for the best results.
She explained: "Making sure our food intake is at least two-thirds plants, and a big variety too, feeds our gut microbes with vital prebiotics (fibre).
"Fermented foods little and often like kefir and sauerkraut provide live probiotics. Looking after our gut health has a profound impact on whole health; even to the point of healthy skin."
