Although sunscreen protects your skin from UV damage, it doesn't protect the coral reefs; many mainstream sunscreen formulas contain chemical ingredients that are harmful to aquatic life, which they are exposed to when your sunscreen wears off in the water. Stream2Sea has created an eco-friendly, biodegradable formula with all natural ingredients to give your skin the UV protection it needs without harming our beloved coral reef. EcoTested and proven formula, this special Sunscreen for Body is highly water resistant and has SPF 30 protection with a mineral base.
