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~3.2–3.9%
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~2.5–3.1%
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~1.7–2.1%
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).~2.2–2.6%
AvobenzoneButyl MethoxydibenzoylmethaneUVA1Avobenzone. An organic, or so-called "chemical" UV filter. Protects against both UVA and UVB rays. Needs to be combined with other filters in a formulation to be stable.~2–2.4%

What the product description says
“Kehrt die sichtbaren Zeichen der Hautalterung um, fördert die Kollagenproduktion, reduziert Falten und verbessert die Strahlkraft der Haut.”
Source: ISDIN

This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.

These ingredients in the product might also be helpful for reducing and preventing fine lines, wrinkles, and skin elasticity, even though there is no conclusive evidence for their effectiveness: lysine.

LysineKey activeEffect: MediumAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.05–0.15%

What the product description says
“Spendet intensive Feuchtigkeit , zieht sofort ein und bietet eine dreifache Anti-Photo-Aging-Wirkung.”
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, dimethicone.

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~6.3–7.8%
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~0.65–0.95%
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~0.5–0.75%
Peg-10 dimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that works to soften the upper layer of the skin and reduce its water loss~0.3–0.55%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.25–0.4%
Porphyridium cruentum extractKey activeEffect: MediumA red algae extract. Can help attract water to the upper layer of the skin and might have an antioxidant effect~0.2–0.4%
LysineKey activeEffect: HighAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.05–0.15%
Dibutyl adipate· EmollientEffect: LowHelps soften the upper layer of the skin and create a nice product consistency~4.5–5.5%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.65–1%
