Natria Sun Screen SPF 30 supplies broad-spectrum UVA and UVB protection. It contains titanium dioxide, considered one of the best forms of sun protection because it works immediately and acts as a physical barrier. Natria Sun Screen is fortified with DNA defense enzymes to protect skin and help improve the look of visible signs of sun-aged skin. Plant extracts soothe and condition, while vitamins A, B, C and E provide antioxidants to counteract the free-radicals caused by sun exposure. Adults and children 6 months of age or older, apply evenly over face and body before sun or water exposure. Reapply after swimming, excessive perspiration or after towel drying.
