Why Zinc Is One of the Best Natural Sunscreens for Surf & Ocean Lovers

Finding an effective sunscreen that stays put in tropical heat, doesn’t sting your eyes when you’re paddling out, protects your skin and the planet can be tough. Many traditional sunscreens slide off in saltwater, feel greasy, or contain chemical filters that aren’t ideal for sensitive skin or marine ecosystems.

That’s where natural zinc oxide sunscreen shines - it’s become a go-to choice for surfers, paddlers, and outdoor water-sport enthusiasts around the world.

Broad-Spectrum Protection You Can Trust

Zinc oxide provides true broad-spectrum protection, meaning it blocks both harmful UVA rays (which contribute to premature aging and DNA damage) and UVB rays (which cause sunburn). This makes it one of the most effective physical sunscreen ingredients available.

Unlike many chemical sunscreens that absorb UV rays and convert them to heat, zinc sits on the skin’s surface and physically reflects and scatters UV radiation - offering reliable protection throughout your session.

Gentle & Safe for All Skin Types

Zinc oxide is non-irritating, hypoallergenic, and gentle, making it ideal for sensitive skin - from sun-burned faces to rosacea or eczema-prone skin. It’s even one of the only sunscreen actives the FDA approves for use on babies.

It’s less likely to cause stinging around the eyes or breakouts compared with many chemical sunscreens, which is essential when you’re spending hours in salty, windy conditions.

Reef-Safe and Environmentally Responsible

Many chemical UV filters (like oxybenzone and octinoxate) have been linked to coral bleaching and harm to marine life. Zinc oxide - especially in non-nano form - is widely considered reef-safe and a much better choice for ocean environments.

For surfers and ocean lovers who care about the waters they ride every day, choosing zinc-based sunscreen is a small but meaningful way to reduce impact on fragile reef ecosystems.

Works Immediately & Lasts Longer

Unlike chemical sunscreens that typically need 20–30 minutes before they become effective, zinc oxide starts protecting your skin the moment you apply it.

It’s also photostable, meaning it holds up well under continuous sunlight without breaking down quickly - perfect for long sessions in the waves.

Ideal for Water Sports

Many zinc oxide formulas are naturally water-resistant and cling better in surf conditions than some chemical alternatives - especially when used with quality natural bases like beeswax or plant oils.

This means you get reliable defense against UV exposure even while swimming, paddling, and sweating - though reapplication is still key depending on sun intensity and time in the water.

Choosing the Right Zinc Sunscreen

Not all zinc products are created equal. When selecting one for ocean days, look for:

• Non-nano zinc oxide (safer for reefs and skin)

• A high SPF broad-spectrum formula

• Natural, skin-friendly ingredients like coconut oil or beeswax

• Water-resistance for active use

Whether you’re heading out for a surf or long SUP session, the right zinc sunscreen can make a big difference for both your skin and the sea you love.

Some Zinc Sunscreens

Here’s some natural zinc sunscreens we’ve come across. They stay put when applied, are made from natural ingredients are easy to apply and won’t harm the environment.

Surfmud - A natural handmade zinc based sunscreen developed by surfers for surfers.

Zinc oxide blocks both UVA and UVB rays of ultraviolet light. Organic bees wax, mineral oil, natural lanolin, coconut oil, Australia clay and iron oxides.
