Water Resistant and non-whitening. The product comes in a non-spill stick formula. 74 oz SPF 25 Sunscreen glides on smooth without a greasy residue and travels easily in a diaper bag or purse. Star Naturals Baby provides natural broad-spectrum UVA/UVB protection without the use of chemical active ingredients or preservatives. Sun protection is created using Zinc Oxide (found in most diaper creams) as a physical blocker that stays on the skin’s surface. Physical blockers do not need to be absorbed by the skin and are effective immediately unlike chemical blockers. Coral Reef Safe.
