Secret in-a-Tube organic anti-aging protection moisturizer sunscreen broad spectrum spf 32 provides true broad-spectrum uva and uvb protection. Uvb is stronger than uva having a greater ability to cause skin damage, and responsible for most sunburns and most responsible for skin cancers. Uva is responsible for most of the premature aging signs, penetrating deep into the skin where it destroys collagen and elastin. The organic sunscreen contains non-Nano uncoated zinc oxide, which is the most natural sunscreen available and protects the skin from the damaging uva, uvb and even uvc rays proven to be responsible for premature signs of aging and sunburns. Zinc oxide is the only sunscreen active ingredient fda-approved for children under 6 months of age. The Secret in-a-Tube sunscreen contains about 90% certified organic ingredients and is completely free of petroleum based chemicals. It is the healthiest and safest sunscreen available, free of toxic chemicals, synthetic fragrances and artificial colorings. It is suitable for all skin types and does not clog pores. The ingredients are biodegradable and do not harm reefs and aquatic environments. It is packaged in 100% recyclable tubes that are bpa and phthalate-free.
