The main thing to know
Blue Lizard publishes no independent lab test screening this sunscreen for heavy metals or benzene. That does not mean it is contaminated, and the two filters are ones the FDA recognizes as safe. It is simply the one thing we could not verify on an otherwise very clean formula, and it matters a little more here because titanium dioxide is a mined mineral. No kids sunscreen we scored publishes that test.
Thinkbaby publishes no independent lab test screening this sunscreen for heavy metals or benzene. That does not mean it is contaminated, but it is one thing we could not verify, and no kids sunscreen we scored publishes that test. The other is that the formula is not fragrance-free, so reactive skin has a cleaner option elsewhere.
Skip this if you...
You want to see a published heavy-metal or benzene certificate of analysis before you buy
You want to avoid the white cast a classic mineral finish leaves on the skin
You need a won't-sting or tear-free promise for applying sunscreen close to a child's eyes
