The physical blockers zinc oxide and titatnium dioxide safely reflect away more than 99 percent of UVA light from baby's delicate skin. It's extremely water resistant and provides more than 30 times the skin's natural protection against UVB rays. Baby Lizard is PABA-, chemical- and fragrance-free. The Smart Bottle packaging turns pink when harmful UVA rays are present, then reverts to its original white under incandescent light. A 5-ounce bottle is also available for $12.50.
