Little Urchin is an Australian natural sunscreen range, all zinc based, reef safe, water resistant and free from UV absorbers, titanium dioxide, parabens, synthetic preservatives and synthetic fragrances. I discovered them when I met the founders on the Mark Bouris show, where they were being interviewed just before me. It's a beautiful clean range with some fantastic products for children. I stock everything they make, and my favourite is the Tinted Face Zinc Sunscreen SPF 50+. It works like a tinted moisturiser with broad spectrum sun protection, and it is titanium dioxide free.
