It refers to the particle size of the zinc oxide. Non-nano particles are larger, which means they sit on the skin's surface rather than being absorbed. Some people prefer this because it means the active ingredient stays where you put it.

No. This is a clear zinc formula, so it blends in without the chalky white layer that older zinc sunscreens were known for.

Yes. It's fragrance free, dermatologically tested, and uses zinc oxide as the active ingredient, which is generally well tolerated by reactive skin. If you're someone who breaks out or stings with chemical sunscreens, mineral is worth trying.

Yes. The formula is gentle enough for facial use and it goes on clear, so it works under makeup or on its own. If you want a sunscreen specifically designed for the face, we also have a dedicated face sunscreen.

Both filter UV effectively. The practical difference is in how they feel and how your skin reacts. Mineral formulas use zinc oxide, which tends to be better tolerated by sensitive or reactive skin. Chemical filters use synthetic actives that some people find irritating.

Yes. It's also fragrance free and contains no animal-derived ingredients.

Every 2 hours as a general rule, or straight away after swimming, sweating, or towelling off. The formula is water resistant for up to 2 hours, but reapplication is what keeps the protection consistent.

For most people it comes down to skin tolerance. Zinc oxide is one of the gentlest UV filters available, which is why it's commonly recommended for sensitive and reactive skin. It's also considered very stable, meaning it doesn't break down as quickly in the sun.

Yes, like all sunscreens. Check the expiry date on the tube. Zinc oxide itself is very stable, but the other ingredients in the formula do break down over time. If it's changed colour, texture, or smell, replace it.
