We love the Sun. It’s amazing. We believe limited, smart exposure is actually pretty o.k. for the skin. But for those long exposure times, Hurraw! SPF 15 Sun Balm will give your lips the extra protection they need. It glides on silky smooth *(and virtually clear) like the regular balms but they formulated it to be extra thick and creamy for longer staying power while out in those shining rays!Active Ingredient: Non-Nano Uncoated Zinc Oxide 10% Here’s the deal with Zinc Oxide. We use non nano Zinc Oxide in our Sun Balm. Zinc Oxide is the only all natural, broad spectrum (blocks both UVA and UVB) sun screen available today. Zinc Oxide is a mineral. It protects your lips by sitting on top of them and thus, provides a physical barrier against UVA and UVB rays. It actually deflects the rays away from the skin to prevent any harm. For adequate protection it must be applied often.
