Designed for precious and snuggly-soft skin, baby gentle mineral-based formula provides 40-minute water resistance without adding fragrances, parabens or other harsh chemicals. With our Smart Bottle Technology, the BPA-free bottle turns pink in the presence of harmful UV rays to remind you to apply sunscreen. The deeper pink the bottle becomes, the more UV rays are present. Blue Lizard Australian Sunscreens have been dermatologist recommended for over 20 years and are trusted by moms who know a thing or two.
