What foods are good for your skin?

Foods that support skin health

Several specific foods and food groups have reasonable evidence for skin health. Understanding which matter helps build practical eating patterns.

Oily fish for omega-3

Salmon, mackerel, sardines, trout and herring provide omega-3 fatty acids that support skin barrier function and may reduce inflammation. Two to three portions weekly meets typical recommendations. Adults disliking fish can use omega-3 supplements (1 to 2 grams daily) as alternative. The omega-3 content is one of the strongest dietary skin connections.

Colourful fruits and vegetables for antioxidants

Berries, tomatoes, carrots, sweet potatoes, peppers and dark leafy greens provide antioxidants including vitamin C, vitamin A precursors and various polyphenols. The antioxidants support skin protection against oxidative damage. Aim for at least 5 portions of different coloured produce daily. Variety matters more than any single food.

Nuts and seeds for vitamin E and zinc

Almonds, walnuts, sunflower seeds, pumpkin seeds and Brazil nuts provide vitamin E, zinc, selenium and healthy fats supporting skin health. A small handful daily provides meaningful nutrition. The combination of nutrients supports multiple skin processes including protection and repair.

Adequate protein for skin structure

Skin is largely protein and requires adequate dietary protein for repair and renewal. Aim for 0.8 to 1.2 grams per kilogram body weight daily through meat, fish, eggs, dairy, legumes, nuts and seeds. Adults eating very low protein diets may experience suboptimal skin renewal. Most UK adults eat adequate protein but vegans and elderly adults may fall short.

Healthy fats for skin barrier

Olive oil, avocados, oily fish, nuts and seeds provide the healthy fats supporting skin barrier function and natural oil production. The Mediterranean diet pattern emphasising these fats has reasonable skin health evidence. Replacing some saturated and trans fats with these healthier alternatives produces modest skin benefits over time.

Practical dietary approach

Adults wanting to support skin through diet can do so through sensible patterns rather than chasing specific superfoods.

Eat oily fish twice weekly

Salmon, mackerel, sardines or other oily fish twice weekly provides omega-3 fatty acids supporting skin health. Tinned fish counts and is affordable. Adults disliking fish can use omega-3 supplements as alternative. The omega-3 intake matters more than the specific food source.

Build meals around vegetables

Make vegetables half of most meal plates. Variety across colours provides different antioxidants. Leafy greens, peppers, tomatoes, sweet potatoes and broccoli all support skin. Fresh, frozen or tinned all work. The volume and variety matter more than freshness or organic status.

Include nuts and seeds daily

Small handful of mixed nuts and seeds daily provides vitamin E, zinc and healthy fats. Add to salads, breakfast, snacks or yogurt. Cheap and convenient. Most adults can easily include this without major dietary changes.

Limit ultra-processed foods

Ultra-processed foods provide minimal nutrients while taking up calorie space that could go to nutrient-dense foods. Limit to under 20 percent of total intake. The dietary pattern improvements compound through both adding good foods and reducing problematic ones.

Stay hydrated through fluids and water-rich foods

Adequate hydration supports skin function. 2 to 3 litres of fluid daily plus water-rich foods like cucumbers, watermelon, tomatoes and leafy greens contribute to skin hydration. Adults consistently dehydrated produce worse skin outcomes than adequately hydrated adults.

For adults wanting to support skin through both quality diet and targeted nutritional supplementation, our Hair, Skin and Nails Gummies deliver biotin, collagen building blocks and other ingredients that complement good dietary patterns.

When to see your GP about skin concerns

Diet supports skin but specific concerns warrant proper assessment. See your GP if any of the following apply.

• Persistent skin conditions. Eczema, psoriasis, severe acne warrant proper assessment.
• Food allergies or intolerances affecting skin. Dermatologist input.
• Significant unexplained skin changes. Investigate properly.
• Nutritional deficiencies suspected. Blood tests through GP.
• Specific dietary needs or restrictions. Dietitian guidance helpful.

Foods most strongly supporting skin health include oily fish, colourful fruits and vegetables, nuts and seeds, adequate protein and healthy fats from olive oil and avocados. The Mediterranean diet pattern combines these reliably. The dietary pattern matters more than any single superfood. Adults eating well most of the time produce better skin outcomes than adults chasing specific skin foods while otherwise eating poorly. Combine good diet with appropriate topical care and lifestyle factors.
