Going to the beach means sunscreen for us – and usually not just once. But while we do something good for ourselves with sunscreen and protect our skin from the damaging rays of the sun, we could unknowingly harm the oceans. Many sun creams protect us with chemical UV filters such as oxybenzone and octocrylene, which are quickly absorbed by our skin and therefore do not leave a white film. Here it becomes problematic for the ocean. While we are having fun in the water freshly sunscreened, some of the sunscreen dissolves and the chemical UV filters get into the water. If these settle on corals, they damage them enormously. Corals get their beautiful bright colors from algae, which live in symbiosis with the corals. These algae are killed by the chemical UV filters found in many sunscreens. The chemical UV filters also influence the DNA of the corals. As a result, the corals bleach and die. Corals are not only an incredibly important habitat for fish and sea plants, but also protect us from some natural disasters.
Another problem for the environment can be nanoparticles in sun creams. In order to reduce the whitening effect with mineral UV filters, the mineral particles are often comminuted to nanosize. The harmlessness of this is still disputed on sensitive skin and children's skin. If the nanoparticles get into the sea, they can harm fish and impair the growth of important microorganisms.
But there our Naseweiss a real Naseweiss is, he knows how to do it better. We deliberately do without chemical UV filters and instead use really good UVA & UVB protection from titanium dioxide & zinc oxide in the non-nano* range - simply because we want to be on the safe side that our products do not harm the environment or people . There is currently still a need for research on other chemical sunscreens and also on the subject of nanoparticles in sunscreen. Even if the bfR comes to the conclusion that nanoparticles are not a problem for the time being, we prefer to play it safe. Despite mineral UV filters, ours whitens Naseweiss Hardly, only on parts of the body with thicker body hair can a slightly visible white film possibly appear, since the cream cannot be absorbed as well there. But we think that's a small price to pay for protecting the oceans.
We are not only concerned with the UV filters Naseweiss thought, but also otherwise rely on few and natural ingredients, and deliberately avoid fragrances.

*The non-nano UV filters we use comply with Regulation (EC) No. 1223/2009 of the European Parliament and Council of November 30, 2009 on cosmetic products. Nanomaterial in this case means that it is an insoluble or biopersistent and intentionally manufactured material with one or more external dimensions or an internal structure on the scale from 1 to 100 nm.
