Effective and natural sun protection, plastic-free, reef safe, and skin-caring. Doesn't exist? Oh yes, it does ;) Kapitän Ohlsen - Zinc Stick Sunscreen is an effective mineral sun protection that effectively repels UVA and UVB rays. We achieve this by adding non-nano zinc oxide. The included coconut oil and shea butter nourish the skin and, in combination with beeswax, provide extreme water resistance. Naturally, the sunscreen comes in a plastic-free push-up stick made from FSC-certified cardboard. I'd be happy to explain what reef safe means. Conventional chemical UV filters (octinoxate and oxybenzone) damage the marine ecosystem and destroy young cells, leading to coral bleaching. In some countries like Hawaii and Palau, these chemical UV filters are already banned. Besides, they are also suspected of causing allergies. But the solution is simple. Mineral sun protection.
