Mom & World Baby Sunscreen SPF 50 is specially formulated to be non-irritant and ideal for baby's sensitive skin. It is non-greasy, non-allergenic and can be used anywhere on the body where the sun is going to shine. It is designed especially for babies, though it is an excellent and safe choice for all ages! Our active ingredients Zinc Oxide and Titanium Dioxide are the safest, broad-spectrum sun protection ingredients available. Tips for Application Be sure to apply sun cream all areas that will be exposed to sunlight, including behind the ears, neck, hands, feet, and scalp 15 minutes before sun exposure. Reapply after 80 minutes of swimming or sweating, immediately after towel drying, at least every 2 hours. While the sunscreen applies very easily, we recommend not spreading it too thin. Otherwise you will decrease the effectiveness of the sunscreen. We continue to expand our products to offer alternatives to existing products on the market. Our efforts are energized by working with leading child advocacy partners & like-minded individuals seeking alternative products. We approach each product with the same criteria: safe, functional, & sustainable.
