Think about it. Babies have the most delicate skin around, so after 6 months of age, using one of the safest sunscreens on the market should be mandatory. ThinkBaby Broad Spectrum Sunscreen (meaning both UVA and UVB protection) is free of nano-particles (particles which are less than 100 nanometres, and can be easily absorbed into the blood stream), PABA and parabens, and hormone disrupting chemicals. ThinkBaby SPF 30 contains a high-zinc content—but no titanium dioxide—and also has antioxidant vitamins C and E to ward off free radicals caused by sunlight. It's safe to say this sunscreen is good enough for your little sunshine.
