Our Story

Sun protection with nothing to hide.

Winki Zinc is an Australian, female-founded brand that started with a straightforward question: why does sunscreen need so many ingredients? Winki Zinc builds every formula around a short, honest list, with non-nano zinc oxide doing the heavy lifting and nothing harmful filling the rest.

How It Started

A beach-loving founder. A broken industry standard.

Winki Zinc was founded by an Australian woman who spent her life in and around the ocean and grew tired of reaching for sunscreens packed with chemicals she didn't want on her skin or in the water. Winki Zinc began as a commitment: create a product that works as hard as the people who use it, without costing the reef anything.

Winki Zinc formulates every product around non-nano zinc oxide, a physical mineral filter that reflects UV rays without absorbing into the bloodstream. Winki Zinc publishes the full ingredient list for every SKU in the range, because transparency is not a marketing line, it is the entire point.

Today Winki Zinc offers mineral sunscreens from SPF 30 to SPF 50, zinc sticks, and tinted options, all wrapped in plastic-free packaging and produced with solar-powered energy.

What Winki Zinc Stands For

Five commitments. No exceptions.

Winki Zinc does not trade one environmental problem for another. Every commitment below applies to every product in the range, every time.

Reef-safe, always.

Winki Zinc uses non-nano zinc oxide as the sole active UV filter. The formula contains no oxybenzone and no octinoxate, two chemicals directly linked to coral bleaching and marine ecosystem damage. Winki Zinc keeps these chemicals out of every product permanently, not as a trend.

Plastic-free packaging.

Winki Zinc ships every product in packaging that contains no single-use plastic. Winki Zinc uses cardboard, aluminium, and fully recyclable materials. The brand's approach to packaging starts from first principles: if the material creates waste that outlives the product, Winki Zinc does not use it.

Eco-friendly cardboard and natural packaging materials

Certified palm oil-free.

Winki Zinc holds certified palm oil-free status across the entire product range. Every ingredient is traced and verified against palm oil derivatives. Winki Zinc treats this certification as a floor, not a ceiling: the brand actively seeks formulation alternatives that support biodiversity from the beach to the rainforest.

Solar-powered operations.

Winki Zinc runs its operations on solar energy, reducing the carbon footprint of every tube and stick from production through to dispatch. Winki Zinc views solar power not as a badge but as a basic standard for a brand that exists because it cares about what happens to the natural world.

Toxin-free ingredients, full stop.

Winki Zinc keeps the ingredient list short and every item earns its place. No parabens, no synthetic fragrance, no endocrine disruptors, no fillers. Winki Zinc believes that a clean ingredient list is an act of respect: for the person wearing the sunscreen and for the environment that eventually receives it.

Female-Founded in Australia

Built on the belief that skin health and ocean health are the same decision.

Winki Zinc is an Australian brand founded by a woman who refused to accept that protecting your skin meant harming the water you swim in. Winki Zinc operates from Australia, sources with care, and ships to Australians who want a sunscreen with a short ingredient list and a clear conscience.

Winki Zinc invites you to read every label, ask every question, and hold the brand to every promise on this page. That kind of accountability is the only way Winki Zinc knows how to operate.
