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.

Moisturizing

Good support

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: glycerin, glycine.

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: dimethicone, butylene glycol dicaprylate/dicaprate.

PolymethylsilsesquioxaneKey activeEffect: HighA silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss~0.45–0.65%

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~0.15–0.25%

Product summary

We assess that "Eucerin - Sun Protection Sun Fluid Face SPF 50" can provide reliable sun protection based on the ingredient list. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

It contains good moisturizing ingredients and can double as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

Sunscreen filters

This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. These are the sun protection ingredients in this sunscreen: tinosorb s 1.10% - 1.40%, avobenzone 1.90% - 2.40%, octisalate 0.80% - 1.20%, homosalate 0.70% - 1.10%, octocrylene 3.20% - 4.00% and ensulizole 1.40% - 1.70%.

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this product to be low. For a detailed overview of all potential irritants: click here
