This product offers a good level of protection against both UVB and UVA rays.

This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

OctisalateEthylhexyl SalicylateUVBOctisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen~2.6–3.2%
EnsulizolePhenylbenzimidazole Sulfonic AcidUVB Photo-stable Ensulizole. A UV filter that is effective against UVB rays. Does not protect against UVA light. It is photostable and can be used to help stabilize other sunscreen ingredients. It is water-soluble meaning that it can help create lighter sunscreen formulations~1.4–1.7%
Uvinul TEthylhexyl TriazoneUVB Photo-stable Uvinul T. A UV filter. Effective against UVB rays. It is photostable. Can increase water resistance properties of the sunscreen. Unfortunately, not approved by the FDA (US) yet~0.6–0.9%
Tinosorb SBis-ethylhexyloxyphenol Methoxyphenyl TriazineUVBUVA Photo-stable Tinosorb S. One of the most effective broad spectrum sunscreen ingredients. Protects from both UVA and UVB rays. It is photostable. Approved by the US FDA in 2026 (listed as bemotrizinol on US labels).~1.9–2.3%

What the product description says
“Feuchtigkeitsspendende Wirkung, trocknet sofort und hat einen erfrischenden Effekt.”
Source: ISDIN

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: arginine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, coco-caprylate/caprate.

Coco-caprylate/caprateKey active· EmollientEffect: MediumHelps to soften the upper layer of the skin without creating a greasy texture~5.4–6.6%
UndecaneKey active· EmollientEffect: MediumHelps create a non-greasy finish on the skin~3.3–4.1%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.6–0.9%
ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.5–0.75%
Dibutyl adipate· EmollientEffect: LowHelps soften the upper layer of the skin and create a nice product consistency~4.6–5.6%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.25–0.5%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.15–0.25%
