Myth: although waterproof sunscreens are more resistant to water than non-waterproof sunscreens, you (and your child!) still need to apply sunscreen onto your body once you’re out of the water. Even the most water-resistant sunscreen can be wiped out by water, sweat, clothes, and it can also just dry out. What about the Sunscreen SPF 30 or SPF 50 for baby & kids? Mineral filter vs chemical filter Our sunscreens have mineral filters. The benefit of this is that, compared to a sunscreen with a chemical filter, it works immediately when you apply the layer onto the skin. Always safety first!
