Stream2sea is plain and simply awesome! Starting off it is biodegradable in under 28 days! It doesn’t absorb into your body causing any health concerns, and majority of the ingredients are plant based. Third party tested safe for all aquatic life. Tested on bait fish it had zero effect on eating behavior! Where typical sunscreen either caused them to stop eating or die. It will leave a slight film on your body which is unnoticeable if you have pale skin. I prefer the tinted, blends with my skin tone the best. If I’m out on the water I will use the untinted(this one). Unlike typical sunscreen it acts as a shield and stays on your skin vs absorbing into your body like typical sunscreen. Which has been found that some of the main ingredients are endocrine disruptors. 3oz bottle with daily application will last one person around 2 months if applied correctly! Makes it cheaper than the typical sunscreen. All tubes are made with sugarcane resin and bottles out of recycled milk jugs. Neither the containers or products contain any petroleum products!
