Sun protectionSPF 50 · 4 UV filtersBroad spectrum
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.
Anti-agingTocopherol, Ascorbyl palmitateStrong evidence
“P20 Urban Shield SPF50+ protects the face and neck from UV-induced skin damage and premature skin aging.”
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.

MoisturizingNot advertised by the brand · Glycerin, Squalane + 9 moreGood evidence
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, butylene glycol.
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: squalane, caprylyl caprylate/caprate.

Product summary
Based on the ingredients included, we believe that "Riemann - P20 Urban Shield Face SPF 50+" can offer reliable sun protection. We love that it can protect from both UVA and UVB rays (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).

They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. The UV filters in this sunscreen are: tinosorb s 3.60% - 4.40%, uvinul a plus 6.90% - 8.40%, uvinul t 1.50% - 1.80% and tinosrob a2b 1.70% - 2.10%.
