Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You have a baby, toddler, or child with sensitive or eczema-prone skin and want the gentlest formula available.
You want a fully disclosed, fragrance-free ingredient list with nothing to second-guess.
You prefer a lotion you can see going on rather than a spray you have to worry about breathing in.
You need real protection in the water and want the full 80-minute water resistance.
You want the safest possible mineral sunscreen for a baby or young child
You prefer fragrance-free formulas because of sensitive or reactive skin
You are comfortable reapplying every 40 minutes when your kids are in and out of the water
You want zinc oxide protection that sits on the skin instead of absorbing into the body
The main thing to know
Because the protection rests on titanium dioxide alone, it gives less reliable coverage against deeper UVA rays than a zinc-based formula. For most families this is a fine everyday choice, but if maximum UVA defense is your priority, a zinc option is the stronger pick.
It is water resistant for 40 minutes, not 80, so set a timer to reapply around water and right after toweling off to keep protection from slipping.
Skip this if you...
You want the strongest, most reliable UVA protection available and should choose a zinc-based option instead.
A visible white cast is a dealbreaker for you and you would rather have a tinted or sheer finish.
You are shopping primarily on price per ounce and want a budget-friendly bottle.
You need the longest 80-minute water resistance for all-day pool or beach days without frequent reapplication
An invisible, no-white-cast finish on deeper skin tones is a must-have for you
You want the cheapest sunscreen per ounce rather than the cleanest formula
Neither of these quite what you're looking for?
