System 2 sunscreen, with powerful Titanium Dioxide, features a unique two-layer system proven to protect skin in the most extreme conditions. One layer penetrates deep into the skin, while the second layer bonds closer to the surface. So while water, sweat or the occasional scratch may remove the top layer, the deeper layer will continue to provide effective UVA/UVB protection. PABA- and fragance-free formula is perfect for sensitive skin. SPF 50. Sizes: 2-oz. tube, 8-oz. tube.
