Kinder Corner’s Quick Sunscreen Summary for Preschool Parents: In sunscreens, high SPFs can be misleading. The safest approach is reapplication after 2 hours or as needed. Retinyl palmitate (vitamin A) can irritate skin and increase photo sensitivity and should be limited to 10% of the sunscreen’s ingredients. The safest bet is PLENTY OF SHADE and light clothing that covers more of a child’s sensitive skin. Have a safe and happy summer!
