Z Blok's sunscreen's unique formula does not contain any fragrances or inexpensive petroleum based ingredients, which may cause your eyes to sting. Z Blok does contain zinc oxide, which helps protect against skin cancer and premature skin aging without eye irritation. Z Blok sunscreen also provides broad-spectrum sun protection from both UVA and UVB rays. It is highly water-resistant so it stays on your skin instead of coming off in the water. Try Z Blok and see the difference that quality ingredients make in a sunscreen.
