Go for it if you...
You want a 100 percent mineral sunscreen, zinc oxide and titanium dioxide, with no chemical UV absorbers
You are shopping for sensitive or reactive skin and need a fragrance-free formula
You want broad-spectrum SPF 50 with full 80-minute water resistance for pool and beach days
You like the color-changing cap that reminds kids to reapply when the sun is strong
You want an all-mineral, zinc-only sunscreen with no chemical UV absorbers
You are shopping for eczema-prone or uber-sensitive skin and need a fragrance-free formula with organic colloidal oatmeal
You are comfortable reapplying every 40 minutes when your kids are in and out of the water
You want broad-spectrum protection that clears the dermatologist SPF floor and sits on the skin instead of absorbing in
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.
Earth Mama publishes no independent lab test screening this sunscreen for heavy metals or benzene. That does not mean it is contaminated, but it is the one thing we could not verify on an otherwise very clean formula, and no kids sunscreen we scored publishes that test.
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
You want to see a published heavy-metal or benzene certificate of analysis before you buy
You need the longest 80-minute water resistance for all-day pool or beach days without frequent reapplication
An invisible, no-white-cast finish is a must-have for you
Neither of these quite what you're looking for?
