We love Eco! We always recommend chemical-free, all-natural sunscreen and this hypoallergenic sunscreen actually absorbs into the skin easily and doesn't leave you looking chalky white. It is water-resistant and nourishing to the skin. This line is even biodegradable so it's earth friendly enough to not harm reefs and ocean life. This sunscreen is very affordable and competitive with conventional brands of sunscreen. There are no chemical UV-absorbers, synthetic preservatives, or titanium dioxide in any of the eco formulas. It is much safer than most sunscreens and free of Parabens, Phthalates, PEG’s (polyethylene glycols), Propylene Glycol, Phenoxyethanol (all of the scary chemicals that you didn't even realize are in most conventional sunscreens.) This is a great sunscreen that works well for sensitive skin as well as for kids and babies. We love that it won’t clog your pores, and it’s great even under makeup. Non-nano zinc oxide is the active ingredient. Eco skin care’s commitment to consumers and to a healthier planet runs throughout the production process. Be sure to read the instructions regarding application frequency.
