NSP^© stands for "natural sun protection" - and is free from harmful sunscreen chemicals.

The NSP^© technology forms a micro-protective film in the skin that naturally protects the skin against UV-A, UV-B and UV-C radiation.

NSP^© strengthens the skin's cell membrane complex and is free from conventional and often very harmful mineral or organic sunscreen ingredients.

Generally, the human skin adapts to natural radiation exposure to radiation based on the respective skin type and reacts to UV radiation exposure using protective mechanisms such as increased production of eleidin (indication: increased pigmentation/tanning) and increased light callosity (indication: thickening of the skin). However, the body's own protective mechanisms are limited and sometimes need a very long time to react and build-up.

The NSP^© technology fills this gap and uses a special chitosan biopolymer complex that directly assimilates UV radiation with application.

Chitosan itself does not assimilate UV radiation - but its UV-sensitive complexes used in NSP^© technology do. These are able to assimilate UV radiation and convert it into heat before it reaches the skin.

DYNADIONproducts with NSP^© technology form a wafer-thin, barely perceptible micro-protective film in the skin, which acts like a protective shield to keep UV radiation away from the skin.

This micro-protective film is also breathable, (salt) water-resistant and abrasion-resistant - and can maintain its sun protection factor (SPF 60 or 65+) over the long term.

The film is removed only by intense rubbing - e.g., when drying the skin with a towel - and needs to be reapplied afterwards.

The NSP^© technology is extremely sweat-resistant - even with intensive, alkaline sweating.

DYNADION sun protection products are extremely waterproof.

The European Cosmetics Association Colipa(https://colipa.eu) and DIN ISO 24442-2011 provide for two categories of water resistance information:

Water-resistant means that at least half of the sun protection factor of a product must still be measurable after two 20-minute standardized bathing sessions. Standardized bathing in this sense is a stay in moving water.

Extra waterproof means that the products still provide this protection after four 20-minute baths.

In addition to these in vivo tests, DIN ISO 24443-2021 also requires in vitro tests.

DYNADION sun shading products significantly exceed these requirements:

The objectives according to DIN ISO 24442-2011 (water resistance in vivo), DIN ISO 16217-2020 (water resistance in vivo) in praxi as well as the objectives according to DIN ISO 24443-2021 (UV protection in vitro) on a laboratory basis were far exceeded, the upper action range was exceeded. This also applies to the requirements of the Food And Drug Administration (FDA) according to U.S. standards.

As part of internal tests in cooperation with the Biological Institute Helgoland (BAH) and the Fraunhofer Institute UMSICHT, daytime sun protection has even been proven.

In addition to its extraordinary sun protection potential (Shield Spray Skin UV 60, Shield Lotion Skin UV 65+ against UV-A, UV-B and UV-C radiation), DYNADION's sunscreen has been confirmed to be extremely durable.

The protection is retained even during sporting activities that go beyond swimming - whether in fresh or salt water. DYNADION sun protection is therefore more than just "extra waterproof" - it is extremely waterproof.

DYNADION sun protection is also extremely sweat-resistant, sand-resistant and friction-resistant.
