Unlike chemical-based sunscreens, P4O and other mineral sunscreens are safe to use on children under 2 years old and while pregnant or nursing. P4O products are designed for all skins, even the most sensitive. At P4O, we believe all skins deserve the best mineral sun protection. They use natural and organic ingredients and exclude all nasties such hormone disruptive ingredients. They include ceramides such as Shea Butter and natural waxes for water resistance, so our sunscreens don't run or sting the eyes. However, they do recommend keeping new-borns (<6 months old) out of the sun or to consult your doctor. Also keep in mind that P4O sunscreens contains essential oils.
