Antioxidants and Skin Health: Glow From the Inside Out

Antioxidants have been all the rage in skincare lately. You’ll see them everywhere in serums, moisturizers, and sunscreens, and for good reason. There is solid evidence that topical antioxidants can help protect the skin from environmental damage and skin aging.

But one piece of the conversation often gets overlooked: the antioxidants we consume naturally through our diet.

What we eat every day plays an important role in how our skin functions, repairs itself, and ages over time. Supporting the skin from the inside out is just as important as what we apply on the surface.

One of the biggest factors affecting how our skin looks and functions is something called oxidative stress.

What Is Oxidative Stress?

Every day, our bodies are exposed to things that create “wear and tear” at the cellular level:

• Sun exposure

• Pollution

• Stress

• Processed foods

• Poor sleep

These factors create unstable molecules called free radicals. When free radicals build up faster than the body can neutralize them, we develop oxidative stress.

Over time, oxidative stress can contribute to:

• Skin aging

• Collagen breakdown (which affects firmness and elasticity)

• A weakened skin barrier

• Increased inflammation in the skin

This is where antioxidants come in.

What Do Antioxidants Do?

Antioxidants help neutralize free radicals and support the body’s natural repair systems. Think of them as part of your body’s internal cleanup crew.

Your body makes some antioxidants on its own, but we also rely heavily on the antioxidants we get from food — especially fruits, vegetables, nuts, seeds, herbs, spices, and healthy fats.

While topical antioxidants can be beneficial, their effectiveness often depends on formulation and stability. Many antioxidant ingredients are sensitive to light and air, which can affect how well they work over time. This is one reason why obtaining antioxidants through whole foods can be such a valuable complement — food-based antioxidants are naturally stable and continuously supplied through the diet.

Antioxidants That Support Skin Health

Many of the most helpful antioxidants come from everyday foods.

🌿 Polyphenols

Polyphenols are found in many plant foods and have anti-inflammatory and antioxidant properties.

Found in:

• Berries

• Green tea

• Extra virgin olive oil

• Dark chocolate

• Herbs and spices such as turmeric, ginger, cinnamon, oregano, cloves, and rosemary

🥕 Carotenoids

Carotenoids are the pigments that give fruits and vegetables their red, orange, and green colors. They accumulate in the skin and contribute to the skin’s natural defenses against UV radiation.

Found in:

• Carrots

• Sweet potatoes

• Tomatoes

• Leafy greens

🍊 Vitamin C

Vitamin C plays an important role in supporting collagen and overall skin structure.

A recent study from the University of Otago in New Zealand showed that eating two SunGold™ kiwifruits per day increased vitamin C levels in the skin and supported markers related to collagen. In other words, vitamin C from food actually reaches the skin.

Found in:

• Kiwifruit

• Citrus fruits

• Bell peppers

• Strawberries

🥑 Vitamin E

Vitamin E helps protect skin cells and supports the skin barrier.

Found in:

• Almonds

• Seeds

• Avocado

• Olive oil

Why Food Matters More Than Supplements

It’s tempting to think a supplement can “fix” everything, but antioxidants tend to work best when they come from whole foods.

Whole foods provide:

• A mix of different antioxidants that work together

• Fiber and healthy fats that improve absorption

• Balance — rather than megadoses

This is one reason eating patterns like the Mediterranean-style diet are linked to healthier skin and healthier aging overall.

Simple Ways to Support Your Skin From Within

Supporting your skin doesn’t require drastic changes or rigid rules. Simple, sustainable choices can make a meaningful difference.

Here are a few gentle goals:

• Eat a variety of colorful fruits and vegetables

• Include vitamin C–rich foods most days

• Use olive oil as your main fat

• Add nuts, seeds, herbs, and spices regularly

• Focus on whole, minimally processed foods

A Final Thought

Skin health isn’t just about topical treatments or quick fixes. It’s shaped by daily habits — including how we nourish our bodies.

Increasing dietary antioxidants can be a simple, complementary way to naturally support your skin from the inside out, alongside good skincare habits and overall healthy lifestyle choices.
