FAQ

Q - Who is Project Reef’s Sunscreen suitable for?

A - All ages and all skin types are welcome to use our product to prevent sun damage.

Q - How should I apply it?

A - Warm the product between your hands and apply generously to your face and skin for ample protection. Reapply regularly, especially after swimming or sweating.

Q - What does “non-nano” mean? 

A - It’s big enough to not be absorbed into your body. It means not a nanometer, which is one billionth of a meter. A nanoparticle is a particle smaller than 100 nanometers. A non-nano particle is larger than 100 nanometers. For reference, there are 25,400,000 nanometers in an inch. Non-nano means that our tiny particles are not tiny enough to enter your bloodstream or the bloodstream of corals and fish. There are 25,400,000 nanometers in an inch.

Q - What’s the difference between Zinc Oxide and Non-Nano Zinc Oxide?

A - Non-nano zinc has larger particles that offer greater UVA protection than nanoparticles. Nano particles are so small that they can be absorbed by your skin and can penetrate the walls of your cells. Non-nanoparticle zinc oxide has large enough particles so they cannot be absorbed into your skin, instead, they sit on top of your skin to protect it.

Q - How is Non-Nano Zinc Oxide different from chemical sunscreens?

A - Non-nano zinc oxide protects against both UVA and UVB ultraviolet light and serves as a physical barrier between UV rays and your skin. It scatters solar radiation and is a great alternative for those who are sensitive to regular sunscreens. Chemical sunscreens are harmful to humans and marine life, non-nano zinc oxide is a safer alternative. Non-nano zinc oxide is also biodegradable.

Q - So is it actually reef/marine safe? 

A - There is no research that claims non-nano zinc oxide is damaging to marine life or coral, and it is not linked to coral bleaching. Nano-particles, on the other hand, are seen as threats. We claim that our products are “Reef-Friendly” because they contain the safest minerals to be used. The most reef-safe option is to use no sunscreen at all and instead opt to use SPF shirts and hats. 

Q - If you’re ocean-friendly why do you use plastic tubes?

A - We have opted to use ocean-bound plastic, which is plastic that would’ve otherwise ended up in our oceans, and our packaging is recyclable.
