Sun Safe from the Inside Out: How To Eat & Supplement To Protect Your Skin from UV Damage

Vancouver, the sun 's a comin' (finally)!

We all know sunscreen is a non-negotiable in any sun protection routine. But what if we told you your diet could also play a powerful role in protecting your skin from the inside out?

Turns out, the foods you eat and the supplements you take can offer some sweet internal protection—reducing the impact of UV rays, supporting skin repair, and helping prevent long-term damage like wrinkles, hyperpigmentation, and even skin cancer.

Here’s 8 tips to supplement / feed your skin’s defenses and become sun-safe from the inside out.

1. Astaxanthin – Nature’s Internal Sunscreen

This deep-red antioxidant, found in marine algae (and the reason salmon and flamingos are pink), is one of the most powerful natural defenses against UV-induced skin aging.

✹ Benefits:

• Reduces sunburn severity

• Improves skin elasticity and hydration

• Neutralizes free radicals caused by UV exposure

🔁 Dose:

4–12 mg per day. Best taken daily during summer or before vacations.

🍣 Food Sources:

• Wild salmon

• Krill

• Trout

2. Lycopene – Red Power for Skin Protection

Found in tomatoes and other red-pigmented fruits, lycopene absorbs both UVA and UVB radiation.

✹ Benefits:

• Reduces redness and skin damage from sun exposure

• Protects against long-term photoaging

🔁 Dose:

10–15 mg daily

🍅 Food Sources:

• Cooked tomatoes (lycopene is more bioavailable when heated)

• Watermelon

• Pink grapefruit

• Red bell peppers

3. Vitamin C – The Repair Boss

Vitamin C doesn’t block UV rays, but it plays a critical role in collagen production and DNA repair, both of which are crucial after sun exposure.

✹ Benefits:

• Reduces inflammation after UV damage

• Supports collagen regeneration

• Protects against oxidative stress

🔁 Dose:

500–1,000 mg/day for skin support

🍊 Food Sources:

• Oranges

• Kiwi

• Strawberries

• Broccoli

4. Vitamin E – The Antioxidant Bodyguard

Vitamin E works best when paired with Vitamin C. Together, they offer synergistic protection—quenching free radicals created by UV rays.

✹ Benefits:

• Reduces skin inflammation and swelling

• Helps prevent photoaging

• Protects skin cell membranes

🔁 Dose:

100–200 IU daily (look for mixed tocopherols)

🥜 Food Sources:

• Almonds

• Sunflower seeds

• Avocados

• Spinach

5. Polyphenols – Plant-Based Photoprotection

These powerful compounds from plant foods can reduce UV-induced oxidative damage and support healthy skin cells.

✹ Key Polyphenols:

• EGCG (from green tea)

• Flavonoids (from dark chocolate, apples, onions)

🍵 Best Food Choices:

• Green tea (2–3 cups/day)

• Dark chocolate (70%+ cocoa)

6. Omega-3 Fatty Acids – Calm the Inflammation

Omega-3s don't block the sun, but they can dramatically reduce the inflammatory response after UV exposure.

✹ Benefits:

1,000–2,000 mg/day (EPA/DHA combined)

🐟 Food Sources:

7. Beta-Carotene & Other Carotenoids – Color = Protection

Beta-carotene and lutein give fruits and vegetables their rich colors and also help protect skin from UV damage by boosting your skin’s defense system.

✹ Benefits:

• Reduces sun sensitivity

• Enhances skin tone and glow

• Protects against premature wrinkles

🔁 Dose:

25–50 mg/day of mixed carotenoids

8. Zinc – The Skin Repair Mineral

Zinc is vital for DNA repair, wound healing, and inflammation control—all especially important after sun exposure.

15–30 mg/day

🥩 Food Sources:

• Oysters

Quick Tips for a Sun-Protective Diet

✅ Eat a rainbow of fruits and veggies ✅ Don’t fear fats—many skin-protective nutrients are fat-soluble ✅ Prioritize marine-based antioxidants in summer ✅ Take supplements consistently for at least 4–6 weeks before intense sun exposure ✅ Hydrate! Well-hydrated skin is more resilient.

Wrap Up

Sunscreen is still essential. But combining it with internal protection from smart food choices and science-backed supplements gives your skin the ultimate armor—glowing, healthy, and resilient in the face of the sun.

Because the best anti-aging approach is a proactive one, from the inside out.
