For those long exposure times, Hurraw's SPF15 Sun Balm will give your lips the extra protection they need. It glides on silky smooth (and virtually clear) like our regular balms but yet it is formulated it to be extra thick and creamy for longer staying power while out in those shining rays! Juicy Tangerine, Roman Chamomile and a hint of Vanilla make it nourishing and calming for your lips. Packed full of amazing cold pressed oils to moisturize, protect and heal. Red Raspberry Seed oil: Exceptionally high in tocopherols, this lovely oil nourishes the lips, is anti-inflammatory and proven to help in the absorbance of the Sun's rays. Sea Buckthorn oil: Super rich and off the charts in essential fatty acids, carotenes, tocopherols, and phytosterols which are great for healing sun-damaged lips. Pomegranate Seed oil: Deeply penetrating and an anti-oxidant powerhouse; remarkable for the outer epidermal layer of the lips. Here's the deal with Zinc Oxide. Hurraw uses 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. As an interesting side note, to get theHurraw SPF 15 factor verified,the balm was laboratory tested on...Humans!
