Our Mission
Built for the beach. Made for the planet.
Winki Zinc starts with one question: what would sunscreen look like if you only put in what skin actually needs? The answer is a short, clean ingredient list anchored by non-nano zinc oxide, the mineral that blocks UV without chemical conversion.
Winki Zinc wraps every product in plastic-free packaging, runs operations on solar power, and holds certified palm oil-free status. The brand does not trade one environmental problem for another.
Our Full StoryWhy Winki Zinc
Nothing hidden. Nothing harmful.
Reef-Safe
Winki Zinc uses non-nano zinc oxide as the sole active ingredient. The formula contains no oxybenzone and no octinoxate, two chemicals linked to coral bleaching.
Plastic-Free Packaging
Winki Zinc ships every product in packaging free from single-use plastic. Cardboard, aluminium, and recyclable materials only.
Certified Palm Oil-Free
Winki Zinc holds certified palm oil-free status. Every ingredient is traced and verified, so the formula supports biodiversity from beach to rainforest.
Solar-Powered
Winki Zinc runs its operations on solar energy, cutting the carbon footprint of every bottle from production through to dispatch.
Toxin-Free Ingredients
Winki Zinc keeps the ingredient list short and honest. No parabens, no synthetic fragrance, no endocrine disruptors. Every ingredient earns its place.
Female-Founded in Australia
Winki Zinc is an Australian, female-founded brand built on the belief that protecting your skin and protecting the planet are the same decision.

The Ingredient Philosophy
If it doesn't belong on your skin, it's not in the bottle.
Winki Zinc builds each formula around non-nano zinc oxide, a physical UV blocker that sits on the skin surface and reflects UV rays without absorbing into the bloodstream. The ingredient list stops there in terms of actives.
The rest of each formula is equally considered: hydrating naturals, skin-calming plant extracts, and nothing else. Winki Zinc publishes the full ingredient list for every product in the range.
