Safe for the rashy-est of skin, Earth Mama’s creamy Uber-Sensitive Mineral Sunscreen Lotion (Broad Spectrum Sunscreen SPF 40) contains plenty of calming organic colloidal oatmeal and organic shea butter (much more than the amount of colloidal oatmeal than is required by the FDA to be in an eczema cream). Thoughtfully formulated so that it’s non-irritating and gentle for sensitive skin, this is a reef-friendly, non-toxic sunscreen with non-nano zinc — that sits on top of the skin rather than being absorbed, so it can scatter sun rays.
